The primary contradiction facing China's agricultural development has shifted from the previous undersupply to structural contradictions. This paper dissects these structural contradictions in terms of sectoral structure, product structure, organizational structure, technical structure, trade structure and spatial structure. Since reform and opening-up in 1978, China has followed a growth-oriented agricultural policy to ensure steady yield increase. Indeed, this policy has effectively increased the output of agricultural produce, safeguarded national food security, and enhanced agricultural production capabilities. However, China's agriculture is yet to become internationally competitive, increase efficiency and farmers' income, and improve the quality and safety of agricultural produce. As China's agricultural development enters into a new stage of comprehensive transition and upgrade, it is essential for China's agricultural policy to shift from the progrowth policy characterized by the dependence on chemical fertilizers and pesticides to an efficiency and quality-oriented policy that pursues green agriculture. 展开更多

The recent outstanding issues," puzzles of farmers, anxiety oflocal government and helplessness ofcentral government," facing Chinese grain security, depend on the lack of national food security strategy. Therefore, we must reconstruct our national food security strategy with a cornerstone of an integrated productivity, the focus control of market regulation forces and the protection of sovereignty. By analyzing the status of integrated productivity, market regulation force and sovereign control, this essay proposes that we should change the concept from " food production" to "foOd management", design the two systems of the interest coordination and the special safeguard, effectively improve the enthusiasm of the government' s undertaking work in grain-producing areas and farmers' farming work, firmly grasp the two initiatives of acquisition and processing of grain and operating inputs, and actively apply recommendations of the two regulators: food exports, processing and conversion. 展开更多
