产业集群对江苏粮食比较优势的影响研究

The Influence of Industrial Clusters on the Comparative Advantage of Grain in Jiangsu Province

本文基于江苏1985-2016年粮食生产的相关数据,对江苏粮食产业的集群集聚效应与粮食生产的比较优势进行实证分析,发现粮食的产业集群集聚效应对其规模优势产生正向影响,但江苏粮食产业集群并不明显,亟待促进农业产业集群;江苏粮食生产效率优势指数一直下降,亟待加大农业机械投入并健全农田设施;产业集群能提高江苏粮食生产规模优势,存在提升规模效应空间;产业集群未能充分提高江苏粮食生产效率优势,亟待提升产业集群度。

Based on the relevant data of grain production in Jiangsu from 1985to 2016,the paper makes an empirical analysis of the clustering effect of the grain industry in Jiangsu and the comparative adVantages of grain production.The results show that theindustrial cluster agglomeration effect of food can have apositiveimpact on its scale advantages.However,Jiangsu's grain industry cluster is not obvious,and it urgently needs to promote agricultural industrial clusters;the index of Jiangsu's grain production efficiency has been declining.It is urgent to increase investment in agricultural machinery and improve farmland facilities;industrial clusters can increase the scale advantages of grain production in Jiangsu Province.The space for increasing the scale effect;the industrial cluster fails to fully improve the advantages of Jiangsu's grain production efficiency,and it is urgent to increase the degree of industrial clusters.
