Abstract
Spatial coupling analysis, cointegration, and the Granger causality test model were adapted from a geographical perspective to analyse the relationship between sci-tech talent and economic growth, as well as their spatial differences in the Pan-Yangtze River Delta from 1998 to 2019. The results demonstrate that the sci-tech talent centre of gravity and economic centre of gravity are close to each other, showing as two parallel chains, and there is higher spatial overlap and variation consistency between centres of gravity. Sci-tech talent and economic growth are in a long-term relationship of equilibrium, showing a better fitting cointegration equation, in which the latter affects the former. Shanghai has the greatest elasticity, with a 2.119 coefficient of sci-tech talent, while Zhejiang has the smallest elasticity with a coefficient of 0.859. There are differences in the causal nexus between sci-tech talent and economic growth. Economic growth has a unidirectional effect on sci-tech talent in Shanghai and Jiangsu while sci-tech talent has a unidirectional effect on economic growth in Zhejiang. There is a bidirectional effect between sci-tech talent and economic growth in Anhui. There is also a unidirectional effect from economic growth to sci-tech talent in the entire Pan-Yangtze River Delta.
Highlights
With social development and progress, science and technology have increasingly become a decisive force for economic growth, and sci-tech talent, as carriers of scientific and technological innovation, have played an increasingly prominent role in economic development [1,2]
From the perspective of geography, this study measures the relationship between sci-tech talent and economic growth in the Pan-Yangtze River Delta from 1998 to 2019, and the results reveal the following
The spatial overlap between the centre of gravity of sci-tech talent and the economic centre of gravity in the Pan-Yangtze River Delta showed a low fluctuation trend; from the perspective of variation consistency, the spatial coupling of the sci-tech talent centre of gravity and the economic centre of gravity in the Pan-Yangtze River Delta presented a wavy trend of first moving in the same direction steadily, moving away in the opposite direction
Summary
With social development and progress, science and technology have increasingly become a decisive force for economic growth, and sci-tech talent, as carriers of scientific and technological innovation, have played an increasingly prominent role in economic development [1,2]. Economic growth has become an important factor in the location choice of sci-tech talent [4], as many scholars have found that sci-tech talent are more inclined to flow into high-grade cities with advanced economic development in location selection [5,6]. Existing studies mainly focus on the agglomeration of regional scitech talent and its role in knowledge spillover or innovation promotion, which can promote regional economic growth [7,8,9,10]. As a specific part of human capital, sci-tach talent is effective with the increasing of human capital, and more varied quantitative measures are aimed at the direct influence of human capital on regional economic development
