市场分割、创新要素流动与省域创新效率的空间相关性研究

Spatial Correlation of Market Segmentation, Innovation Factor Flow and Provincial Innovation Efficiency

摘要:

本文运用动态空间计量模型对我国30个省（市、自治区）2003～2016年面板数据进行实证分析，旨在探究市场分割与省域创新效率的空间相关性，并揭示创新要素流动在两者中发挥的传导机制。研究发现：市场分割程度有下降的趋势，但其对创新效率依然有十分显著的抑制作用，这种抑制作用表现为中东西逐一递减。进一步探究发现创新要素流动的中介作用十分显著，其中市场分割通过阻碍R&D人员流动进而抑制创新效率的中介效应大于R&D资本；在东中西三大区域中，创新要素流动的中介作用具有差异性，呈现中-东-西的下降趋势。

Abstract:

This paper uses dynamic spatial econometric model to empirically analyze panel data of 30 provinces (cities, autonomous regions) in China from 2003 to 2016, aiming to explore the spatial correlation between market segmentation and provincial innovation efficiency, and reveal The transmission mechanism of innovation factor flow plays a role in both. The study found that the degree of market segmentation has a downward trend, but it still has a very significant inhibitory effect on the efficiency of innovation. This inhibition is manifested by the diminishing of Chinese and Western. Further exploration reveals that the mediating role of the flow of innovation elements is very significant. The mediation effect of market segmentation by inhibiting the flow of R&D personnel and inhibiting innovation efficiency is greater than that of R&D capital. In the three regions of East, Central and West, the mediating role of innovation factor flows is different. The downward trend of China-East-West.
