科技创新对农业高质量发展的影响及区域差异

Impact of scientific and technological innovation on the high-quality development of agriculture and its regional differences

加快核心科学技术创新对驱动农业高质量发展极具重要性。本研究基于2010-2020年省级面板数据,利用熵值法、固定效应模型和空间杜宾模型探究科技创新对中国农业高质量发展的影响和区域差异以及空间溢出效应。研究结果表明,2010-2020年,中国科技创新水平和农业高质量发展水平整体上升;科技创新对农业高质量发展的影响存在区域异质性,对中部地区和粮食主产区作用效果较明显,对东部地区和非粮食主产区的作用次之,而对西部地区的作用不显著;科技创新对农业高质量发展存在正向空间溢出效应,且对毗邻省份的间接影响高于对该省的直接影响。所以应继续加大科技投入,统筹规划各地区农业发展,充分发挥科技创新的辐射作用,实现农业整体高质量发展。

Accelerating core scientific and technological innovation is of great importance to driving high-quality agricultural development.Based on the provincial panel data from 2010 to 2020,this paper used the entropy method,fixed effect model and spatial Durbin model to study the impact of scientific and technological innovation on China’s high-quality agricultural development,as well as regional differences and spatial spillover effects.The results showed that the level of China’s scientific and technological innovation and high-quality agricultural development in 2010-2020 rised as a whole.Scientific and technological innovation showed influence of regional heterogeneity in the development of high-quality agriculture,the effect was obvious on the central region and major grain producing areas,and the effect on the eastern region and non-major grain producing areas was the second,while the effect on the western region was not significant.Scientific and technological innovation had a positive spatial spillover effect on the high-quality development of agriculture,and the indirect impact on adjacent provinces was higher than the direct impact on the province.Therefore,we should continue to increase investment in science and technology,make overall plans for agricultural development in different regions,give full play to the radiation effect of scientific and technological innovation,so as to achieve overall high-quality development of agriculture.
