Why do provincial governments change policy, even when those policies have proven successful? This paper explores a debate regarding the determinants of provincial policy choice and the degree of discretion provinces are permitted in this area. It does so by scrutinizing the shift in Guizhou's development policy from a poverty reduction orientation to a wholehearted pursuit of economic growth, urbanization and industrialization. In contrast to those who argue that central experience, prospects for promotion or local conditions are key factors explaining policy choice, the paper concludes that Guizhou's shift in policy had more to do with the backgrounds and experiences of top provincial leaders. The result has implications for our understanding of central–local relations and local government decision making.
