摘要:粮食作为人们生活中必不可少的组成部分,是经济发展和社会稳定的重要基础。在素有“鱼米之乡”之称的江苏省常熟市,近年来由于城市化和工业化进程的加快,耕地面积逐渐减少,但其粮食产量仍保持着较好的发展水平,因此,研究常熟市的粮食生产情况以及可能影响产量各个因素,对于如何进一步提高产量有一定的现实意义。本课题准备以江苏省常熟市为例,将常熟市的粮食产量作为研究对象,并收集了常熟市1996-2013年的农业生产数据,打算运用计量经济学的方法,通过建立线性回归方程来分析常熟市的粮食生产情况,希望通过分析能够提出一些具有针对性的政策建议,来完善常熟市的粮食生产。66933

Abstract: As the indispensable part in our daily life, Grain is also an important foundation for economic development and social stability. Changshu City, which in Jiangsu Province, is known as the "land flowing with milk and honey ".In recent years, due to the urbanization and the industrialization, the farmland has decreased gradually, but its grain’s output still developed well. Therefore, to study on the grain production of Changshu City and its influencing factors, is meaningful for further improvement of grain’s output. In this paper, it plans to take Changshu City, Jiangsu Province for example and takes the grain production of Changshu as research object. Using already-collected agricultural statistical data of Changshu City during 1996-2013, the paper plans to use the method of econometrics by establishing the linear regression equation to analyze the Changshu’s grain production situation, and hope that through the analysis, some targeted recommendations can be put forward to improve the Changshu’s grain production.
