Abstract

This paper makes an empirical analysis of the spatial spillover effect of regional economic growth by using Moran’s I and Spatial Durbin Model to study the input and output of technological progress, with the panel data of 21 prefecture-level cities in Guangdong Province from 2008 to 2017. The empirical results show that the spatial autocorrelation exists in the economic development of Guangdong Province, and both the input and output of scientific research innovation have a significant positive effect on the regional economic growth. Under the spatial contiguity weights matrix, the output of scientific research and innovation has a more obvious spillover effect on the economic growth of neighboring cities than the input of scientific research and innovation.

Highlights

Since Economic Reform and open up, China’s regional economic development is mainly concentrated in the eastern coastal areas
The empirical results show that the spatial autocorrelation exists in the economic development of Guangdong Province, and both the input and output of scientific research innovation have a significant positive effect on the regional economic growth
This paper focuses on the effect of the input and output of technological innovation on regional economic growth, taking into account the practical role of scientific and technological innovation on social production, so the R & D expenditure of the whole society of the city in that year is taken as the index of input, and the number of urban patent authorization in that year is taken as the index of output

Summary

Introduction

Since Economic Reform and open up, China’s regional economic development is mainly concentrated in the eastern coastal areas. Scientific and technological innovation is the internal driving force for the further growth of regional economy. The existing literature mostly takes the input of scientific and technological innovation and economic growth rate as the research focus, ignoring the competition of scientific and technological innovation between neighboring regions will increase the investment of funds. The space spillover effect makes it easy to underestimate the impact of technological innovation on the quality of regional economic development. This paper takes 21 cities in Guangdong Province as an example, uses the panel data from 2008 to 2017, and adopts the Spatial Durbin Model to study the spatial spillover effect of input and output of scientific and technological innovation on regional economic growth
