In January I had the honor to present some ongoing research at the 2015 China Smart Energy Summit, at the invitation of the Energy Foundation. My presentation was cleverly called “Smart Energy in China.” It was a tremendously interesting day and there was a strong feeling of possibility in the overflow crowd about meaningful changes in China’s energy landscape.
I’m active on the Q&A social media site Quora, where I often take on questions on urban planning and economics, transportation, technology and China. From time to time I will share answers here.
Answer by Don Johnson:
To the extent all cities around the world throughout history are similar, Chinese and American cities are similar. But in pretty much every other possible way, they are different. I’ll hit only the big differences.
China has a highly centralized governmental organization chart that cities fit into. Most cities are governed by provinces, and in turn administer districts and rural county centers. (Beijing, Shanghai, Tianjin and Chongqing are independent of provinces and are administered directly by the central government.) Chinese cities are geographically huge and most include large hinterlands around their urban areas, which gives them a level of administrative control most American cities only dream of. On the other hand, Chinese cities are subservient to provinces and must follow their policies.
Within the areas they have power over, American cities are independent – counties and states can’t tell them what to do. (This often surprises Chinese people, who take it for granted that higher jurisdictions rule lower ones, like the army.) It’s actually quite common for cities to have policies in direct conflict with those of the state they’re in. American cities tend to be geographically small, and it’s extremely common to have many cities making up a single metropolitan area – sometimes hundreds of cities (e.g. Los Angeles.) At the metropolitan level there is often only a very weak association of cities to try and coordinate regional policy. So American cities are often bad at addressing regional problems like housing, schools, environment, transportation, economic development…
Urban Design and Development
Chinese cities are dense and tall. Here’s Shenzhen:
American cities are ridiculously low density – from the air many of them look like a few blocks of skyscrapers surrounded by forest. I give you Minneapolis:
From a historical point of view, a lot of Chinese cities are very old (although a surprising number are not) but from a construction point of view they are very young. It’s ironic that in China, which tends to go on about its 5,000 years of history, it can be difficult to find a building that’s more than 30 years old, outside a few preserved areas in major cities. Buildings from the 1980s or early 1990s are considered old and crappy – and they often look it. By contrast, it’s quite common for American cities to have large areas dominated by buildings from the late nineteenth and early 20th century, and cities on the east coast have (a few) neighborhoods of buildings that are over 200 years old.
The density gives Chinese cities an urbanity and bustle that only the largest American cities (really, only New York) can rival. Chinese visitors to America invariably mention that American cities seem empty – where are all the people? (Hint: They’re in cars, driving around.) Americans conversely are often put off by the physical crush of people on the streets. Even on quiet side streets, you will always see people going about their daily business.
Downtown Philadelphia: Where is everybody?
It should surprise nobody that America is the land of the car. With the big exception of New York, travel in American cities is heavily dominated by people driving, even in cities that have decent bus and subway systems, bike lanes, and other alternatives. (See Transportation: Which North American cities are the least dependent upon car ownership?) An American city that can get 20% of people traveling to work in anything other than their own car, alone, is considered a model. Urban development is heavily shaped by the need to provide parking for all those people driving.
Downtown Lousiville, KY: More parking than city
Transportation in China can vary a lot between cities, but nowhere is driving the most common mode (although it often feels like it in Beijing.) Chinese cities, even small ones, have excellent bus systems, and many Chinese cities are now building metros. Depending on the city, lots of people bike or take scooters, and electric scooters are a common choice that’s almost completely absent in American cities.
Even within this enormous difference there are differences; American cities’ bike share is low but (in places) growing rapidly, while in Chinese cities it’s generally high – but falling rapidly.
Maybe, with Chinese cities modernizing and American cities urbanizing, these differences will be slightly less prominent in future years. There are surely more cars in Chinese cities now, and more people on downtown streets in the US. But I don’t think you’ll have trouble telling them apart for some time.
The November issue of Planning, the magazine of the American Planning Association, includes this article of mine weighing the importance of China’s first national urbanization plan. If you’re an APA member, you can read it online as html or digital edition. If not, I reproduce it below – with a bonus image:
China Rethinks Urbanization
Its new plan is a big policy overhaul.
This spring, planners in China calling for a more sustainable model of urban development gained a surprising new ally: the State Council, China’s highest level of government. The National New-Style Urbanization Plan, released in March, is a comprehensive policy document based on the conviction that while China’s growing cities will continue to be the country’s main economic engine, the current model of urbanization has hit its limits and needs a complete overhaul.
The plan is part of a gradual but significant shift in planning practice in China, and planners working there say it is already making a difference. John Law, AICP, planning leader in Skidmore, Owings & Merrill’s Shanghai office, says, “We saw the document and realized it would be very beneficial to us, since client education in what makes up a quality urban environment forms a big part of what we do. Now we have a high-level government plan supporting us.”
For decades, China has been undergoing what may be the largest internal migration in history. About 260 million rural workers have left their farms for urban factories and construction sites, according to a recent World Bank report, “Urban China: Toward Efficient, Inclusive and Sustainable Urbanization.” The construction boom is visible in almost every urban area, with expressways, railroads, shopping centers, business parks, and massive blocks of high-rise apartments mushrooming out of cities and popping up across the countryside. Some 600 million people have worked their way out of poverty, and for millions more middle-class living standards are now a reality.
Far from running its course, China is now preparing for the next wave of urbanization, and the plan is testament to its intention to do it differently. China is still less urban than other nations at similar levels of development, like Malaysia, Mexico, and Brazil, let alone developed nations like the U.S. and Japan. China proposes to add a daunting 100 million additional residents to its cities by 2020, according to the World Bank, yet the economic and environmental landscape has completely changed since China’s urbanization was first unleashed in the early 1980s.
The current model of urbanization is the product of several high-level policies that maintain tight control over urban growth: the household registration or hukou system, which restrains labor migration; collective ownership of rural land, which keeps individual farmers from selling or leasing the land they work; a finance system that all but forces cities to take and sell rural land for development; and national urban codes that impose a rigid separation of land uses in superblocks.
These regulations have prevented some of the worst features of urbanization found across the developing world; there are no sprawling favelas or unmanaged slums surrounding China’s cities. But many agree that China’s model has also come with high environmental, social, economic, and (crucially) political costs that cumulatively are holding China back.
Already the compromises and contradictions of breakneck urbanization are apparent. The environmental costs are grim. In arid northern China, half of water resources can’t be used for drinking, and a quarter of them are so polluted they can’t be used at all. City dwellers across the country now routinely check the local air quality index along with the weather before going out.
Many migrants are jammed into substandard housing, poorly served by infrastructure and social services, while ubiquitous new districts of isolated superblocks provide a shallow and unsustainable urban life. China today is a socialist nation in which a third of the population has no social safety net, and the gap between rich and poor is growing. Local governments seize land from farmers to finance development but still face crushing levels of debt from quasi-
legal loans. The last wave of migration fueled China’s immense economic expansion, but the next wave threatens to overwhelm it.
If successful, the National New-Style Urbanization Plan will not only repair China’s cities but also reknit local government finances and social fabric and wean the economy off injections of urban infrastructure investment. If it fails, China risks falling into the “middle-income trap,” a cycle of low productivity and deteriorating demographics, unable to maintain its infrastructure and beset by worsening traffic, pollution, and housing problems. Either way the effects will be felt worldwide: China is big enough to affect the global economy and worldwide climate in the coming decades.
Evolution of the plan
The plan is widely understood to have the backing of Premier Li Keqiang, China’s second most powerful leader after President Xi Jinping and a long-time advocate of economic reform. Li took the unusual step of involving partners outside the Chinese government, proposing a research partnership on urbanization between the State Council’s Development Research Center, the Ministry of Finance, and the World Bank. Together they produced “Urban China,” an exhaustively researched policy white paper that serves as the plan’s foundation.
The ministries involved in urban development have all publicly signed on: Housing and Urban and Rural Development, Land and National Resources, Public Security (which oversees the household registration system), and the influential National Development and Reform Commission (NDRC, responsible for national macroeconomic planning.) This plan is not an advisory document, but one meant to embody policy and guide regulation.
Although the plan’s focus is urbanization, the real goal is economic transformation. Zhuo Xian, an associate researcher with the State Council Development Research Center and a member of the team that wrote the World Bank report, writes in an article in Shanghai Economic Commentary: “Unlike a specific city plan, the Urbanization Plan includes nearly all of the disciplines involved in China’s economic and social development. … How to break the systemic barriers preventing factor mobility and improve the efficiency of resource allocation, thus freeing the potential of economic development and propelling China’s modernization, is the logical chain behind the eloquence of the Urbanization [Plan].”
According to Zhuo, the plan’s focus is on three significant reforms: labor mobility, land controls, and local government finance.
Labor, land, and finance
Labor mobility in China is limited by the hukou system of household registration. Rural residents may move to the cities to find work, but it’s hard for them to settle permanently because their registered residence stays in the countryside. They can’t register for health insurance or social security in the cities, and despite legal guarantees their children often are blocked from local schools. They end up being “guest workers” in their own country, often disdained by city residents, and they are not full participants in the urban economy.
In these circumstances, migrant workers tend to live as cheaply as possible and save nearly all their wages. This is one driver of China’s abnormally high ratios of savings and investment, and a roadblock to developing a robust consumer economy. The urbanization plan calls for loosening hukou restrictions to reap the double economic benefits of workers moving from low-productivity rural work to higher productivity urban labor — and being confident enough in their new lives to spend their wages.
Meanwhile, as professor Chen Jie of the Institute of Public Policy and Governance at the Shanghai University of Finance and Economics said in an interview, “Land reform in the countryside is politically difficult, but it is the way to true urbanization.”
Currently, workers are tied to land rights in the countryside that they can’t capitalize if they move to the city. At the same time, with rural land held in collectives, it is easy for village leaders to cut deals with real estate developers; most of China’s demonstrations and riots involve taking land without villagers’ consent or adequate compensation.
Giving rural residents the ability to sell the right to work the land they farm — which the plan calls for, while it also carefully avoids the politically sensitive concept of outright land sales — would allow them to migrate and give them starting capital when they do. It also would make it easier for rural land, most of which is currently fragmented in tiny plots, to be assembled and farmed more efficiently.
The flip side of land reform is fixing public finance, which is distorting both the process and the form of urbanization. There is no property tax in China, so the primary way local governments finance future development — and even ongoing expenses — is by taking farmland at agricultural prices (with or without consent) and then selling it in large chunks to developers as urban land. Many times the peasants who previously worked the land are resettled on it in new apartment buildings, having gained only a fraction of its value and having lost the means to make a living.
This kind of false urbanization is made worse by the ongoing need for land sales, which tends to push urbanization to the edges of urban areas and even to disconnected pockets outside it. Combined with huge development plots and restrictive separated use urban codes, the result is “urban” development that is internally inefficient, unconnected to existing development, and lacking any underlying reason for existence. The plan calls for ending exploitative development practices and giving local governments sustainable sources of income.
Smart growth, Chinese style
The plan also takes on the physical model of development. The supporting World Bank report is firm in saying that improving the quality and efficiency of China’s cities must be an integral part of urbanization reform, partly because the average population density in China’s cities “has dropped by more than 25 percent in the last decade.” For American visitors, the notion that Chinese cities are not dense enough is almost laughable, but the World Bank is referring not to the city cores but to the wide swaths of newly developed land on the outskirts.China’s new urban districts are almost universally built on an “edge city” model: unconnected developments of high-rise buildings set among vast boulevards, gigantic setbacks, and isolated commercial centers. Because cities and districts compete for investments, China on average uses more than a quarter of its urban land for industry, compared with less than 10 percent in Seoul and Hong Kong, according to the World Bank report. The upshot is that Chinese cities have plenty of room to densify while increasing usable open space and improving quality of life.Consequently, the plan is groundbreaking for its explicit call to change the physical model of development. One development goal titled “scientific and rational urban development” calls for a “high density, mixed-use, intensive and compact transit-oriented development model to become dominant.” While this kind of language is now standard in the U.S., it is pioneering for an official policy plan in China.Justin Huang, AICP, the planning and urban design director of Sasaki Associates’ China office, says the concept of good urbanism is still a new concept in China: “We see a lot of generic principles, but planners need to get to the next level of applying them to specific sites.” He says China’s planning system, in which legal control plans must be drawn up and stamped by a local design institute in accordance with national codes, is a barrier to new approaches.
“Right now planning codes are a challenge; national and local codes are a powerful tool for control, but they are hard to change” at the LDI level, Huang says.
The importance of a plan — even one without detailed regulations or the force of law — is magnified in a highly regulated economy such as China’s, and the plan is already important as a statement of principles. But its lasting significance depends on how it is implemented: Real changes in how urbanization takes place will require supporting regulations.
In the plan, implementation and evaluation are left to the NDRC, although the document makes clear that ministries and local governments will have to cooperate. A common view among Chinese academics I spoke to is that the plan offers nothing truly new, and that its significance lies in the message that the government is intent on implementation. Given the complexity and political sensitivity of key elements in the plan, John Law of SOM says, “It may be that the plan takes longer than 2020 to fully implement. But we see the trend as more important than the timeline.”
There are challenges. Eliminating hukou restrictions is one of those ideas that everyone supports: Most cities already have some kind of a point system in place, in which residents with higher education, or those who invest in businesses or property, can eventually convert their temporary residence permits to an urban hukou. But bringing all rural migrants into the system immediately would cost trillions of yuan and break local governments. The plan calls for gradual expansion of residence permits and hukou benefits; it acknowledges that all migrants cannot be included by 2020.
To reform local government financing, pilot property tax schemes have been floated in Chongqing and Shanghai, but the number of properties they cover is minimal. Currently real estate is cheap to hold but expensive to sell, and upending this balance is a change that few municipalities are eager to take on even as their debt levels grow. Recently local governments have also been allowed to sell bonds, so they can theoretically get cheaper financing. But this may also have limited short-term effects.
“The immediate effect will be small, since local government finances are not transparent, and the market may not find them attractive,” says Chen Jie. “But in the long term, bonds will be another financing option for local governments.”
One challenge to reform is the assumption that the real purpose of the plan is to prop up growth through continuing infrastructure investment. It does contain specific service targets for the national high-speed rail and highway networks, and it advocates the widespread replacement of substandard housing. And several Chinese scholars I talked to, who asked not to be named, confirmed there is a widespread assumption that stimulus — an influx of government spending to boost economic growth — is a big part of the plan.
On the other hand, SOM’s Law says, “Beyond the economic driver for this plan, I think China’s leaders are interested in using smarter urbanization as an opportunity to also address issues of environmental quality, water and food safety, and urban livability.”
Finally, there are policy contradictions within the plan itself. While China wants rural workers to move to cities, the plan suggests small and medium-sized cities instead of the three megacities of Beijing, Shanghai, and the Pearl River delta region (Guangzhou, Shenzhen, and Hong Kong.) Already, urban hukou in small and medium-sized cities are often relatively easy to get — but of course these are not as desirable.
The World Bank’s work suggests that channeling migration this way is bucking economic history, and from an efficiency point of view China’s largest cities should be allowed to grow. The question is important because China’s smaller cities have sunk huge investments into infrastructure, housing, and new commercial and industrial districts. Real estate analysts say these have the greatest risk of becoming “ghost cities,” unsupported by real demand.
John Law says the market for SOM’s services started changing before the plan was released. “There has already been a shift from single-use projects to more mixed use, transit-oriented, and commercial,” he says. Justin Huang of Sasaki also foresees long-term reform, pointing to the evolution in urban development concepts in the U.S. in the past few decades, which were the result of efforts from both public and private sectors.
“Chinese leaders travel a lot and see the most cutting-edge designs in the world, and they adapt,” Huang says. “The planning mechanisms are still very conservative, but they may change very quickly once there is consensus from the government.”
Law also sees alignment with public opinion on the issue of protecting local culture. “This is a reaction to previous development replacing villages with endless high-rise towers in which everything looks the same,” he says. “One of the aspects of the plan that we are most excited about is that of cultural preservation. We are hoping to see projects with more aggressive preservation strategies by the local municipalities that will allow us to highlight and strengthen the region’s unique character and reflect local culture.”
The New Urbanization Plan marks a turning point in China’s development. Its message is that the old model of investment-led growth at city fringes needs to give way to a new focus on efficiency, resource protection, and quality of growth over quantity. If China’s leaders follow through with the difficult reforms necessary to see the plan realized, development will gradually shift from showpiece new districts to urban rejuvenation, and there will be a new focus on environmental and cultural resources and quality of life.

In an excellent article, Bloomberg highlights a glaring contradiction in China’s recent “New Urbanization” plan. The plan calls for a number of wide-ranging reforms in land reform, labor migration policy, urban planning and local government finance in order to fuel another decade of economic growth, in a more sustainable way.
But at the same time, the plan continues a long standing national policy of trying to steer growth away from the megacities of Beijing, Shanghai and the Pearl River delta in favor of small and medium-sized cities. It’s an understandable impulse – it seems natural to want to spread growth around the country, and boosting smaller cities would pull some of the pressure off the housing, transport and environmental pressures the big cities are fighting.
But it’s a mistake. The reason people are still flocking to the big cities in spite of those problems is that’s where the opportunity is. China’s (and every nation’s) biggest cities are also the disproportionate drivers of growth and innovation. The World Bank/State Council Development Research Center report behind the New Urbanization plan concluded that China was giving up significant economic growth by limiting the size of big cities. And while big cities’ environmental challenges are equally big, it’s much easier and more efficient to deal with them in concentrated form than spread all over the country. Beijing, Shanghai, Guangzhou and Shenzhen are enormous – but comparing China to other nations, you would expect them to be even bigger. There is a strong suspicion that an important reason why China’s leaders still try to channel urbanization to smaller cities is the tremendous sums that have been spent there on new urban districts that need residents and commercial tenants.
The examples of Tokyo and Seoul show that huge, very dense cities can still support a very high quality of life and environment. Instead of trying to cap its big cities, the State Council should be leading the effort to improve them.
I discuss these same issues at greater length (and, I hope, depth) in an upcoming article in Planning Magazine.
Cory Doctorow, courtesy of the New Statesman. Add this to the list of potential applications of smart city technology, under “Public Safety:”
Last month the security firm ESD America found dozens of “fake” mobile-phone towers across the US which were extracting data from users who unknowingly connected to them. Similar towers have been used at protests by police forces around the world to monitor activists. Doctorow argues that a government (he cites Ukraine as an example) could react to a protest by cross-referencing that data with information gleaned from domestic internet connections, because anti-digital piracy legislation often mandates “taps” on home web connections. Then it’s a simple job to establish protesters’ names and addresses. If they have a new smart thermostat, which is connected to the web, the state could even extract individual protesters’ thermostat ID. “Then they just cut off everybody’s heat that night,” he says. “Problem solved, done in one.”
Last week ULI Asia Pacific released its report (pdf download) on urban regeneration principles for Shanghai, with an afternoon forum and cocktail party.
Most of the principles – design for people, conserve cultural heritage, “vitalize” public spaces, etc. – are pretty general and will not be news to anyone who has been following smart growth ideas for the last decade or so. But of course a lot of government officials and developers don’t fall into that category, and I hope they may find this a mind-opening read. The report itself is readable and attractive; the numerous case studies from China and around the world, including several that are not on the most seen list, are particularly welcome.
The forum was short but more than usually interesting for events of its kind, as there was a good mix of experienced developers and forward-thinking city planners. There was a particularly good (in my opinion) discussion on whether existing codes inhibit good regeneration projects and what should be done about them.
To me the most notable thing about the report is that urban regeneration as a practice is steadily gaining notice and diversifying from the simple slum clearance role it has traditionally played in China. It’s not surprising that ULI has chosen to champion regeneration, as it’s a stronghold of international firms that are not competing for large-scale new “neighborhoods” being built wholesale at the urban fringes. But there is more than that going on – the number of good urban regeneration projects in all of China used to be countable on one hand, but now there is a dizzying range, and large cities have multiple examples of different types. I see a complementary market evolution going on, in which customer preferences (for rough-hewn workshop space and twee little tea rooms, for example) are changing just as fast as the industry is.
The next step is to provide more specifics at the project level, and more financing and policy support at the macro level. I’d like to see this get built into the “new-style urbanization” planning which is going on nationally and in cities, and I believe this is happening.
…although people seem a bit confused about exactly how, er, spooky they are. If you’ve been to one of them, the answer is easy: very spooky. Walking around a giant new development, full of fresh concrete but devoid of traffic and people, is strangely unsettling. But this is one instance in which your gut instinct that something is very wrong, might be wrong.
These places definitely exist. The question is, how many ghost cities are just new areas that will gradually fill in and take on life, and how many are colossal monuments to waste and fraud? The good news is that two recent studies have added a new level of rigor to the reporting, which previously has tended to be a more or less informed version of, “Wow, there are no people here!” The bad news is that even with the new data, it’s still not clear how big a problem ghost cities really are for China’s economy.
The two reports provide badly needed primary research on the conundrum of China’s real estate markets. The first, from real estate brokers CLSA in Hong Kong, looked at over 800,000 units in 12 cities. I haven’t been able to find the original report, but CNBC reports:
It estimates China’s vacancy rate at around 15 percent of property completed in the past five years… Among housing over five years old, units smaller than 90 square meters (968 square feet) and tier-one housing, the occupancy rate exceeds 88 percent, CLSA said…
While China’s vacancy rates may appear high compared with international standards, such as the average 10 percent rate in the U.S., oversupply is uneven, CLSA said. Tier-one cities’ vacancy rate is just 10 percent, while the rate is around 16 percent or higher in tier-three cities, it noted.
These results are further evidence that the Tier 1 markets of Beijing, Shanghai and the Pearl River Delta are in a completely different situation from smaller cities. CLSA’s Nicole Wong was quoted in other articles above saying that they see the primary danger of “ghost cities” as coming from tier three cities with much weaker overall demand. The overall picture it paints is that the ghost cities problem is real, but confined to specific smaller city markets.
Unfortunately the China Household Finance Survey at the Southwestern University of Finance and Economics is not nearly as reassuring. In a June 10 speech in Beijing Survey leader Li Gan estimated that the survey, which canvassed 8,400 households from 2011-2013, found much higher vacancy rates: 22.4% for all urban housing, and very troubling 23.3% for affordable housing. If so, there are serious problems in the housing development industry which can’t be explained away by focusing on particular sub-markets.
Like everyone else, I’d like to know which of these two pictures is the right one. Is China is wasting billions of yuan in investments that nobody can use, and amassing huge levels of debt in the process? Or will the additional 10 million new urban residents expected by 2020 make all of this moot? Or both?
My article, “Smart City Development in China” is in the China Business Review this week. It is in some sense a condensed and updated version of what I learned about China researching the “Smart Cities: Asia Pacific” report late last year. There is also more discussion of the challenges that international (especially American) technology firms face in the Chinese market, an issue which keeps returning with every flareup in the China-US relationship. After writing the article, here are the main ongoing questions I was left with:
To what extent is China’s smart city investment push a real attempt to solve urban problems, and to what extent is it just another way to package infrastructure investment and support GDP growth? I suspect the answer is that it depends on who you ask — The policy managers in Beijing are really looking to the benefits of the technology and the industry, and local leaders often are just packaging the investment they want in terms they think are most palatable to the center.
Can Chinese smart city projects move beyond a relatively simple “informatization” of systems to create really transformative connections between them? For example, putting sensors on buses to show arrival times is useful. But connecting the bus sensors to traffic prediction analytics, electric grid balancing systems, public safety cameras, and so forth will really change the way cities work. This question applies around the world, but I think especially in China, where officials are moving fast to implement simple projects without (so far as I have seen) much thought about larger systems. On the other hand, you could argue that getting simple systems in place as building blocks for more comprehensive ones is actually better than trying to design something that nobody yet really understands.
Will China’s extremely young open data and civic hacking movements be able to develop a healthy counterbalance to the collection of civic data (including personal data) in official hands? Feng Gao, the Open Knowledge ambassador for China, is a great person to follow on this question.
I’m active on the Q&A social media site Quora, where I often take on questions on urban planning and economics, transportation, technology and China. From time to time I will share answers here.
Answer by Don Johnson:
Yes, but not nearly as many as in other large developing countries.
Huge areas of informally built housing on the edges of cities that aren’t served by utilities or public services, like you see in India, Brazil and Africa, basically don’t exist in China. However, there areas in many Chinese cities called “城中村,” meaning villages in the city, which are slums: very crowded, very poor infrastructure (single water taps serving hundreds of people, no sewage treatment,) few or no parks, open spaces, schools or hospitals. They are almost completely populated by migrant workers.
These places are former villages that have been swallowed up by expanding cities. The former villagers usually live elsewhere in the city and are now landlords, renting out their old houses to migrant workers who need a very cheap place to stay. One big difference between these areas and typical developing world slums is that most people that live in them are employed, and don’t consider themselves permanent residents. They also don’t have the culture that slum areas in other countries have despite their poverty – more like temporary very cheap worker housing.
Many Chinese cities have made it a priority to demolish “villages in the city” and rebuild the areas with better quality. The problem is that this eliminates badly needed low-cost housing for migrant workers; replacement housing usually is more expensive, even if affordable housing is included.
I just read this very long and absolutely brilliant article (from which the above photo is lifted) on the housing crisis in San Francisco, in TechCrunch of all places. It’s completely worth it from the housing policy, governance, or simply good journalism angles, but it also had this very interesting bit to say about the intersection of tech and cities:
But the big wave [of Silicon Valley activity] of the last decade has been social networking. And every notable consumer web or mobile product of this wave has been seeded through critical mass in the “analog” world. Facebook had university campuses. Snapchat had Southern California high schools. Foursquare had Lower Manhattan. Twitter had San Francisco. These products favor social density.
People have been trying to figure out the connection between the virtual and physical worlds since at least Bill Mitchell’s 1996 book City of Bits, and this link between particular social media and particular physical environments is one I haven’t seen before. We already know great cities can be tremendously different – Paris and Seattle? Tokyo and Edinburgh? – but it’s interesting to think about how different kinds of cities might birth different kinds of social media. Perhaps physical places leave shadows on the web, after all.
