我国粮食产量影响因素分析

Analysis of the Influencing Factors of Grain Production in China

摘要: 本文基于2015年我国31个省或自治区的横截面数据以及柯布–道格拉斯生产函数，建立了多元回归模型，通过几个模型的比较分析，认为我国当前粮食产量主要影响因素为播种面积和有效灌溉面积。为了我国的粮食安全，国家应当积极保护耕地，减少耕地占用，其次科教兴国，努力提高我国农业生产力。

Abstract: Based on the cross-sectional data of 31 provinces or autonomous regions in China in 2015 and the Cob-Douglas production function, the multivariate regression model is established. Through the comparative analysis of several models, it is concluded that the main factors affecting the current grain production in China are sowing area and effective irrigation area. For the sake of our country’s food security, the country should actively protect cultivated land, prevent the occupation of arable land, then rejuvenate the country through science and education, and strive to improve China’s agricultural productivity.
