环境友好农业技术创新与农业经济增长关系研究

Research of Relationship Between Environmentally-friendly Agricultural Technology Innovation and Agricultural Economic Growth

推进环境友好农业技术创新是实现农业增长模式转型、农业可持续发展和农业经济增长的重要途径。本文首先从理论角度分析了环境友好农业技术创新与传统农业技术创新的区别,认为二者本质相同但在创新驱动要素、知识供给源等方面存在差异,在此基础上理清环境友好农业技术创新与农业经济增长的关系。其次,引入环境友好农业技术推广程度为过渡指标,运用VAR模型从实证角度分析环境友好农业技术创新与农业经济增长之间的长期动态关系。结果表明:在整体上,环境友好农业技术创新每增加1%,引起农业经济增长增加0.375%,而环境友好技术推广程度每增加1%,则引起农业经济增长增加0.542%;在短期内,环境友好农业技术创新在滞后2期与滞后3期才缓慢地显现出来对农业经济增长的促进作用,具有滞后性;在长期内,环境友好农业技术创新和技术创新推广程度对经济增长的推进作用是缓慢且长期有效的,而农业经济增长是环境友好农业技术创新持续的动力,对技术创新的推广起到先强后弱的促进作用。最后建议从促进环境友好农业技术创新成果转化、完善环境友好农业技术创新政策机制、改革环境友好农业技术创新资金投入制度等方面进行政策调整,使得环境友好农业技术创新更有效地促进我国农业经济可持续增长。

Promoting environmentally-friendly agricultural technology innovation is an important way to transform agricultural growth pattern, achieve agricultural sustainable development, and accelerate agricultural economic growth. This paper at first studied the difference between environmentally-friendly agricultural technology innovation and traditional agricultural technology innovation from the perspective of theory, found that they have the same essence hut have such differences as innovation driving factor and knowledge supply source, and analyzed the relationship between environmentally-friendly agricultural technology innovation and agricultural economic growth. Secondly, the writer introduced environmentally-friendly agriculture technology extension as interim index, and researched on their log-term dynamic relationship by means of VAR model from an empirical view. It was found that 1% growth of environmentally-friendly agricultural technology innovation will cause agricultural economic growth increasing 0. 375% as a whole, and 1% growth of environmentally-friendly agriculture technology extension will resultin agricultural economic growth increasing 0. 542% ; In the short term, the promoting effect of environmentally-friendly agricultural technology innovation for agricultural economic growth appears at the second and the third lag phases, while in the long term, the promoting effect takes much longer, and agricultural economic growth is the driving force for environmentally-friendly agricultural technology innovation, and the promoting effect for technical innovation decreases progressively. Finally, it is recommended to promote achievement transformation, improve innovation policy mechanism, and reform funding institutions in order to making environmentally-friendly agricultural technology innovation promote agricultural economic sustainable growth more effectively.
