中国农业能源偏向型技术创新测度及结构优化研究
Measurement and Structure Improvement of Agricultural Energy Biased Technical Innovation in China

近年来全球气候变化及农业生产所引发的环境问题和食品安全问题频发，客观上引起了人们对农业能源偏向型技术创新的重视。基于CES生产函数模型与实证分析，本文测度了2005年至2015年间我国农业技术创新的能源偏向性及其效率。研究结果表明：2005年至2015年，我国农业技术创新总体上是偏向非能源要素的使用，即资本和劳动，但能源要素偏向型技术的效率高于非能源要素偏向型技术的效率，非能源要素与能源要素是互补的。因此，要减缓全球气候变暖、改善生态环境、保障食品安全必须开展农业能源偏向型技术创新,进一步优化能源结构。
The trouble of environmental pollution and food safety caused by global climate change and agricultural production happened frequently in recent years,which has drawn people's attention to the energy biased technical innovation of agriculture.Based on the CES production function and empirical analysis, studying the energy bias and efficiency of agricultural technique in China from 2005 to 2015.The results show that the agricultural technical innovation more relies on the use of non-energy factors such as capital and labor, but the efficiency of energybiased technique is higher than the non-energy biased technique, they are complementary. Therefore, it is necessary to promote the agricultural energy biased technical innovation and improve the structure of energy, in order to decrease the emission of CO2,improve the ecological environment and ensure food safety.
