Agricultural R&D Input and Agricultural Total Factor Productivity: An Explanation and Evidence from the Perspective of Spatial Spillover

Abstract

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
