我国农业信息化贡献率测算方法实证研究

Empirical Study on the Calculation Method of Agricultural Informationization's Contribution Rate in China

研究了农业信息化贡献率的测算方法,首先采用层次分析法构建了适合我国国情的农业信息化水平评价指标体系,并运用综合指数法测算出2007—2016年各年度的农业信息化水平指数。在此基础上,运用经济增长理论构建了加入信息化要素的C-D生产函数,通过回归分析研究了农业信息化与农业经济增长之间的相关关系,计算出近年来我国农业信息化对农业经济增长的贡献率。

This paper studied the calculation method of agricultural informationization's contribution rate. This paper firstly established an indicator system of agricultural informationization level evaluation for the situations in China by the analytic hierarchy process( AHP). Then this paper adopted synthetical index method to calculate the annual index of agricultural informationization level from 2007 to 2016. Based on the calculation,this paper used the theory of economic growth to build the C-D production function with adding the element of informationization index,and analyzed the relationship between agricultural informationization and agricultural economy development by means of regression analysis,and finally calculated agricultural informationization's contribution rate in China in recent years.
