【摘要】：粮食是关系国计民生的特殊商品和重要战略物资。近些年来,世界粮食供需矛盾日趋尖锐,粮食安全问题更加凸显。中国政府始终高度重视粮食安全问题,自2004年开始就在全国范围内实行粮食直接补贴政策来调动农民种植粮食的积极性。在国家政策的支持和刺激下,我国粮食产量实现了“九连增”。江苏省作为我国重要的粮食主产区之一,一直以来认真贯彻落实财政支农的各项政策。早在2003年,江苏省就率先在省内五个产量大县试点粮食直补政策,随着近几年的不断完善,江苏省粮食直接补贴体系逐渐形成,其促进农民增产增收的效应也日益显现。因此认真研究江苏省粮食补贴的现状以及粮食直接补贴政策对粮食产量的影响,对于完善江苏省的粮食补贴政策,确保本省粮食产量的自给,维护区域粮食安全具有重要的现实意义。本文在粮食直接补贴理论基础、粮食直接补贴产量效应的经济学分析以及粮食直接补贴产量效应作用路径等相关理论分析的基础上,对江苏省粮食直接补贴政策的演变历程和实施现状进行分析研究。然后本文采用扩展的C-D函数构建了包涵粮食直接补贴政策变量以及该变量与其他生产要素变量的交叉项在内的江苏省粮食生产函数,运用2004-2012年江苏省13市的面板数据对粮食直接补贴政策对江苏省粮食产量的总体影响以及对江苏省苏南、苏中、苏北三个地区粮食产量的影响进行了实证检验。研究结果表明粮食直接补贴政策在总体上对江苏省粮食产量有重要,并且比较显著的影响,其可以通过影响农民从事粮食生产活动的行为来影响粮食产量。但不同区域的粮食直补政策产量效果却表现出不同的特征,这取决于三个区域要素禀赋的差异以及经济发展的不平衡性。最后,本文针对这些结论提出了相应的政策建议,认为应该逐步提高粮食直接补贴的标准；并建立江苏省粮食直接补贴与粮食市场价格和农资价格三者间的联动机制；鼓励分地区、分品种实行不同的粮食直接补贴政策；鼓励农村土地承包经营权的流转,加快农村剩余劳动力的转移。
[Abstract]:Grain is a special commodity and important strategic material related to the national economy and people's livelihood. In recent years, the world grain supply and demand contradictions are increasingly acute, food security issues are more prominent. The Chinese government has always attached great importance to the issue of food security. Since 2004, the Chinese government has been implementing a nationwide policy of direct grain subsidies to arouse farmers' enthusiasm for grain cultivation. With the support and stimulation of the state policy, China's grain production has achieved "nine consecutive increases". As one of the most important grain producing areas in China, Jiangsu Province has been carrying out the policies of supporting agriculture. As early as 2003, Jiangsu Province took the lead in experimenting with grain direct subsidy policy in five large output counties in Jiangsu Province. With the continuous improvement in recent years, the direct grain subsidy system in Jiangsu Province gradually formed, and its effect on increasing farmers' production and income is also increasingly apparent. Therefore, a careful study of the current situation of grain subsidies in Jiangsu Province and the impact of direct grain subsidy policies on grain production will improve the grain subsidy policy in Jiangsu Province and ensure the self-sufficiency of grain production in Jiangsu Province. It is of great practical significance to maintain regional food security. Based on the theoretical basis of grain direct subsidy, the economic analysis of grain direct subsidy yield effect and the path of grain direct subsidy yield effect, This paper analyzes the evolution and implementation of direct grain subsidy policy in Jiangsu Province. Then the paper constructs the grain production function of Jiangsu province including the policy variable of grain direct subsidy and the cross-term between this variable and other factors of production by using the extended C ~ (?) D function. Based on the panel data of 13 cities in Jiangsu Province from 2004 to 2012, the overall effect of direct grain subsidy policy on grain output in Jiangsu Province and the effects on grain output in three regions of Jiangsu Province, Southern Jiangsu, Central Jiangsu and Northern Jiangsu, were empirically tested. The results show that the grain direct subsidy policy has an important influence on the grain yield in Jiangsu Province in general, and it can affect the grain yield by affecting the farmers' behavior to engage in grain production activities. However, the yield effect of grain direct supplement policy in different regions shows different characteristics, which depends on the difference of factor endowment among the three regions and the imbalance of economic development. Finally, according to these conclusions, this paper puts forward the corresponding policy suggestions, thinks that the standard of grain direct subsidy should be raised step by step, and establishes the linkage mechanism between grain direct subsidy and grain market price and agricultural price in Jiangsu Province, and puts forward some suggestions on the relationship between grain direct subsidy and grain market price and agricultural price. We should encourage sub-regions and varieties to implement different grain subsidy policies, encourage the transfer of rural land contractual management rights, and speed up the transfer of rural surplus labor force.
