The slowing of China’s economic growth has many causes. In my view, it is a healthy development, resulting from a necessary change in China’s growth model. Since the beginning of China’s growth miracle, a large part of the country’s development has been directed from the center. This top-down approach has focused on heavy industry, infrastructure, and the promotion of exports. This growth model had its roots in central planning, but China also encourages market liberalization and openness to international competition, thus making significant gains in productivity and technological upgrading. This strategy has been incredibly successful: The Chinese economy is two-and-a-half times bigger today than a decade ago.
   However, the top-down strategy has its limits. The share of economic output going into manufacturing, infrastructure, and exports is too large to be sustained, and there is overemphasis on investment and exports rather than on consumption. Recognizing these limits, China is working to make the transition to a bottom-up growth model, focused on the development of service industries, that is, retail trade, health, education, finance, and transportation. Services currently make up about half of the Chinese economy, compared to about four-fifths of the economy of the United States. As productivity in services generally does not grow as quickly as in manufacturing, this transition will involve slower economic growth.
   The experience of some old American industrial cities like Pittsburg offers useful lessons to China as it goes through this crucial economic transition. The economy of Pittsburgh was built on heavy manufacturing, a model that eventually reached its limits. And heavy industry took a heavy toll on its environment. Pittsburgh and other industrial American cities that succeeded in reviving their economies did so primarily by turning from manufacturing to services. In these cities, the government and the private sector worked together to revitalize downtowns, develop tourist attractions and conference facilities, clean up the environment, and improve transportation links and other critical infrastructure. They then attract businesses in clean sectors like medicine, technology, finance, and retail.
   Strengthening education was the key, as it has benefits like attracting and maintaining skilled workforces and setting up high-tech companies. Pittsburgh’s redevelopment was greatly helped by hosting several major universities, particularly the University of Pittsburgh, which led efforts to build research facilities where old factories had once stood. A symbol of Pittsburgh’s transformation is the former U.S. steel building in downtown Pittsburgh, the headquarters of a steel company. It is now the University of Pittsburgh Medical Center, which is the largest employer in the whole region. How can China make a transition to a more service-oriented economy, like Pittsburgh has done? Reducing subsidies to exports and heavy industry, while continuing reforms to make it easier to start new businesses is a critical step. China can also enter into partnerships with foreign companies that can bring essential expertise in various fields.
   Reviving old American industrial cities like Pittsburg offers a useful lesson to China, which is the building of a strong middle class. Middle-class households are the primary market for a wide range of services, from education to healthcare to retail to entertainment. For American cities like Pittsburg, attracting middle-class consumers involved improving public infrastructure and education, reducing crime, and increasing job opportunities. In the case of China, to build a strong middle class, it needs to strengthen the social safety net, as this will give households income security so that they can save less and spend more. It also needs to reduce excessive government regulations and provide more consumer choices. A strong Chinese middle class will stimulate the development of new services and give the bottom-up approach a chance to succeed.
