Abstract

Declining arable land and yield stagnation pose serious challenges to food security in China. Since 2004, the Chinese government has introduced rice support policies to stimulate rice production. A bundle of incentives, including a minimum procurement price, were introduced. Whether they were effective? Rice acreages have increased since the start of this policy, which could also result from rising rice price levels both nationally and globally. Using a natural experiment created by the minimum procurement price policy being introduced in a selected set of Chinese regions, we use a dynamic fixed effects model to perform a difference-in-differences analysis on the effectiveness of these rice support policies. We find that indica rice acreages do respond to changes in the rice prices, and, controlling for rice prices, that China’s rice support policies were effective in increasing rice acreages of both early and late indica after 2004. The paper concludes with policy implications.

中国水稻扶持政策对水稻种植面积的影响

耕地面积减少和产量停滞不前给中国的粮食安全带来了严峻挑战。2004 年以来，中国政府出台了水稻扶持政策，以刺激水稻生产。出台了包括最低收购价在内的一系列激励措施。这些政策是否有效？自该政策开始实施以来，水稻种植面积有所增加，这也可能是国内和全球大米价格上涨的结果。通过在中国部分地区推行最低收购价政策这一自然实验，我们使用动态固定效应模型对这些水稻扶持政策的效果进行了差异分析。我们发现，籼稻种植面积确实对稻米价格的变化做出了反应，而且在控制稻米价格的情况下，中国的稻米扶持政策在 2004 年后有效地增加了早籼稻和晚籼稻的种植面积。本文最后提出了政策启示。

期刊介绍： Food Security is a wide audience, interdisciplinary, international journal dedicated to the procurement, access (economic and physical), and quality of food, in all its dimensions. Scales range from the individual to communities, and to the world food system. We strive to publish high-quality scientific articles, where quality includes, but is not limited to, the quality and clarity of text, and the validity of methods and approaches. Food Security is the initiative of a distinguished international group of scientists from different disciplines who hold a deep concern for the challenge of global food security, together with a vision of the power of shared knowledge as a means of meeting that challenge. To address the challenge of global food security, the journal seeks to address the constraints - physical, biological and socio-economic - which not only limit food production but also the ability of people to access a healthy diet. From this perspective, the journal covers the following areas: Global food needs: the mismatch between population and the ability to provide adequate nutrition Global food potential and global food production Natural constraints to satisfying global food needs: § Climate, climate variability, and climate change § Desertification and flooding § Natural disasters § Soils, soil quality and threats to soils, edaphic and other abiotic constraints to production § Biotic constraints to production, pathogens, pests, and weeds in their effects on sustainable production The sociological contexts of food production, access, quality, and consumption. Nutrition, food quality and food safety. Socio-political factors that impinge on the ability to satisfy global food needs: § Land, agricultural and food policy § International relations and trade § Access to food § Financial policy § Wars and ethnic unrest Research policies and priorities to ensure food security in its various dimensions.
