陕西省农业科技进步贡献率的测算与分析——基于C-D生产函数

Measurement and Analysis on Contribution Rate of Agricultural Science and Technology Progress in Shaanxi Province:Based on C-D Production Function

利用陕西省农业物资消耗、耕地面积以及农业劳动力投入三个指标,运用C-D生产函数模型对2001-2007年陕西省的农业科技进步率和农业科技进步贡献率进行了测算,得出此时间段陕西省的农业科技进步贡献率为49.6%。在此基础上,根据陕西省现代农业发展的趋势性规律,进一步预测出2011年陕西省农业科技贡献率有望达到55%。陕西省农业物资消耗、耕地面积以及农业劳动力投入等要素的平均增长率和贡献份额的测算结果显示,陕西省农业尚处于传统农业向现代农业过渡的阶段,低水平的农业科技成为制约陕西省现代农业发展的瓶颈。

This paper uses the data of agricultural goods and materials,the area of arable land and the input of agricultural labor to calculates the rate of agricultural technology progress and the contribution rate of agricultural technology progress in Shaanxi province in the period of 2001 to 2007 by the C-D production function model,and obtains the contribution rate of agricultural technology progress in Shaanxi province during this period is 49.6%.And then it forecasts the contribution rate of agricultural technology progress in 2011 which will be up to 55%.Finally,it gives some suggestion for improving the technological progress of agriculture in Shaanxi.
