China’s economy during the past 30 years has changed from a centrally planned system that was largely closed to international trade to a more market-oriented economy that has a rapidly growing private sector and is a major player in the global economy.

Reforms started in the late 1970s with the phasing out of collectivized agriculture, and expanded to include the gradual liberalization of prices, fiscal decentralization, increased autonomy for state enterprises, the foundation of a diversified banking system, the development of stock markets, the rapid growth of the non-state sector, and the opening to foreign trade and investment. Annual inflows of foreign direct investment rose to nearly $84 billion in 2007. China has generally implemented reforms in a gradualist or piecemeal fashion.

In recent years, China has re-invigorated its support for leading state-owned enterprises in sectors it considers important to “economic security,” explicitly looking to foster globally competitive national champions. After keeping its currency tightly linked to the US dollar for years, China in July 2005 revalued its currency by 2.1% against the US dollar and moved to an exchange rate system that references a basket of currencies.

Cumulative appreciation of the renminbi against the US dollar since the end of the dollar peg was more than 20% by late 2008, but the exchange rate has changed little since the onset of the global financial crisis. The restructuring of the economy and resulting efficiency gains have contributed to a more than tenfold increase in GDP since 1978. Measured on a purchasing power parity (PPP) basis that adjusts for price differences, China in 2008 stood as the second-largest economy in the world after the US, although in per capita terms the country is still lower middle-income.

The Chinese government faces numerous economic development challenges, including: (a) strengthening its social safety net, including pension and health system reform, to counteract a high domestic savings rate and correspondingly low domestic demand; (b) sustaining adequate job growth for tens of millions of migrants, new entrants to the work force, and workers laid off from state-owned enterprises deemed not worth saving; (c) reducing corruption and other economic crimes; and (d) containing environmental damage and social strife related to the economy’s rapid transformation. Economic development has been more rapid in coastal provinces than in the interior, and approximately 200 million rural laborers and their dependents have relocated to urban areas to find work – in recent years many have returned to their villages.
