摘要
在C-D生产函数的基础上引入科技投入因素,构建新的生产函数模型,采用2003～2014年山东省数据估计山东省小麦产量的生产函数,从而确定科技投入对小麦产量的贡献率.结果表明:科技投入对山东省小麦产量增加具有显著的正向作用,贡献率为0.178 543,已超过劳动力的贡献率.
Abstract
Based on the C-D production function,science and technology investment factors were introduced to construct a new production function model.By using data of 2003-2014,the production function of wheat yield in Shandong Province was estimated,the contribution rate of technology input on wheat output was determined.The results showed that science and technology investment has a significant positive effect on the increase of wheat production in Shandong Province with the contribution rate of 0.178 543,which has exceeded the contribution rate of labor force.
