Report Says China Puts Growth at Risk Unless It Eases Grip on Economy.

SHANGHAI -- A new study by the World Bank and a Chinese government research organization warns that the country's economic growth is likely to diminish over the next few decades unless China alters its development model and rethinks the role of government in managing the economy. The report, called ''China 2030,'' and produced by the bank and the Development Research Center, the government research organization, calls on Beijing to complete the transition to a market economy, scale back the power of state-owned companies, encourage private enterprise and confront rising inequality and environmental degradation.
