While Chongqing’s model is the most influential, there is an alternative. Chengdu, Sichuan’s largest municipality, with a population of 14 million — half of them rural residents — is less heavy-handed. It is the only city in China to enjoy high economic growth while also reducing the income gap between urban and rural residents over the past decade.

Chengdu has focused on improving the surrounding countryside, rather than encouraging large-scale migration to the city. The government has shifted 30 percent of its resources to its rural areas and encouraged development zones that allow rural residents to earn higher salaries and to reap the educational, cultural and medical benefits of urban life.

I recently visited a development zone composed of small firms that export fiery Sichuan chili sauces. Most farmers rented their land and worked in the development zone, but those who wanted to stay on their plots were allowed to. So far, one-third of the area’s farmland has been converted into larger-scale agricultural operations that have increased efficiency.

More than 90 percent of the municipality’s rural residents are now covered by a medical plan, and the government has introduced a more comprehensive pension scheme. Rural schools have been upgraded to the point that their facilities now surpass those in some of Chengdu’s urban schools, and teachers from rural areas are sent to the city for training.

Empowering rural residents by providing more job opportunities and better welfare raises their purchasing power, helping China boost domestic consumption. And in 2012, Chengdu is likely to become the first big Chinese municipality to wipe out the legal distinction between its urban and rural residents, allowing rural people to move to the city if they choose.

Chengdu’s success has been driven by a comprehensive, long-term effort involving consultation and participation from the bottom up, as well as a clear property rights scheme. By contrast, Chongqing has relied on state power and the dislocation of millions to achieve similar results. If Chengdu’s “gentle” model proves to be more effective at reducing the income gap, it can set a model for the rest of the country, just as Shenzhen set a model for market reforms.
