Economies of scale and mechanization in Chinese corn and wheat production

ABSTRACT As the growth in Chinese farm productivity slowed down between 2000 and 2010, modernizing agriculture has become a priority of the Chinese government. Given the important role of mechanization and land reform policies in that context, this study investigates farm production in China with a specific emphasis on the potential role of mechanization as well as land and farm consolidation. A production function is estimated using farm household data on corn and wheat production in the Shandong and Hebei provinces. The results allowed us to explore the potential economies of scale across a range of farm size, the impact of land fragmentation, and assess the impact of machinery usage. Our findings suggest that, taken in isolation, the prospect for efficiency gains from mechanization and land reforms appears limited.
