ABSTRACT
Government policies play a major role in crop diversity at the farm and aggregate levels in China. An examination of recent trends in the wheat economy in China reveals several significant policy changes that have altered outcomes in China’s wheat economy: decollectivization, market reform, and associated changes in incentives. Those impacts have affected both the quantity of production and the wheat diversity observed. This chapter examines various elements of policy change and their impacts on wheat diversity. Changes in the research and extension systems and the household responsibility system are found to be among the most important influences on wheat crop diversity in China.
