Measurement of City's Science and Technology Talent Flow and Its Impact on Green Total Factor Productivity:Based on Spatial Regression Model
摘要
Abstract
This paper revises the gravity model based on the entropy weight method,defines and calculates the flow level of science and technology talents in 283 Chinese cities from 2003 to 2019.Also,the multi-scale geographical weighted regression model is combined with the spatial error model to analyze the global and local impact of the flow level of science and technology talents in Chinese cities on green total factor productivity.The findings indicate the flow level of science and technology talents between cities has gradually increased,and the siphon phenomenon of scientific and technological talents in big cities has become more obvious,showing a trend of polarization.On the whole,the influence of the flow level of science and technology talents on the green total factor productivity is the promotion effect of diminishing marginal effect.From a regional perspective,the spatial differences of local effects are increasing,gradually forming a distribution feature of"strong in the south and weak in the north".The flow level of science and technology talents has a negative impact on green total factor productivity in some cities in the central and western regions.关键词
