中国农业基础设施的规模效应及其区域差异研究

基于动态性视角,运用系统性广义矩估计方法,构建经济增长与财政支出规模理论模型,依据2000-2013 年中国农业基础设施的省级面板数据,考量中国农业基础设施对农业经济增长的规模效应.结果显示:中国农业基础设施存在规模效应,北方地区规模效应明显强于南方地区,南方地区农业基础设施正由规模经济向规模不经济转变.鉴此,应转变农业基础设施重点区域投向与农业基础设施的项目投向,促进农业经济增长.

Research on the Scale Effect and Region Difference Existing in Chinese Agricultural Infrastructure

Using the System GMM and constructing economic growth and fiscal expenditure scale theory model, this paper considers the scale effect of the contribution of the agricultural infrastructure to the agricultural economic growth with the provincial panel data of Chinese gricultural infrastructure collected from 2000 to 2013. The results show that the scale effect exists in the Chinese agricultural infrastructure,and that effect of the northern region is much stronger than that in the south, and the agricultural infrastructure in South China is transforming from the scale economy to the diseconomies of scale. In view of this,the investments in the key area of the agricultural infrastructure and the project investment should be transformed to improve the agricultural economic growth.
