摘要/Abstract

摘要： 在运用空间经济学理论构建理论分析框架,对农业R&D投入促进农业全要素生产率增长的作用机制进行分析的基础上,以中国31 个省份2000—2018年的数据,采用空间杜宾模型实证检验农业R&D投入对农业全要素生产率的空间溢出效应。结果表明,农业R&D投入与农业全要素生产率均存在明显的空间正相关性。农业R&D投入促进了农业全要素生产率提升,且其空间溢出效应在东部各省份表现得更加充分,中西部地区间的差异则不明显;经济发展水平、人力资本、对外开放以及财政支农等因素均呈现不同程度的空间外溢和区域异质性特征。这一结论为促进农业研发要素的合理配置,提升农业全要素生产率和促进农业经济增长提供了政策启示。

Abstract: On the basis of building a theoretical analytical framework by employing the theory of spatial economics to analyze the influencing mechanism of agricultural R&D investment on the promotion of the growth of agricultural total factor productivity, this paper adopts the spatial Dubin model to empirically test the spatial spillover effect of agricultural R&D input on agricultural total factor productivity with the data of 31 provinces in China from 2000 to 2018. The results show that there is a significant spatial positive correlation between agricultural R&D input and agricultural total factor productivity. Agricultural R&D investment has promoted the increase of agricultural total factor productivity, and its spatial spillover effect has been more fully exhibited in eastern provinces, while the differences between the central and western regions are not obvious. Such factors as economic development level, human capital, opening to the outside world, and fiscal support for agriculture also exhibit different degrees of spatial spillover and regional heterogeneity. This conclusion can provide policy inspiration for promoting the rational allocation of agricultural R&D elements, improving agricultural total factor productivity and promoting agricultural economic growth.

Key words: agricultural R&D input, agricultural total factor productivity, spatial spillover effect
