要素禀赋、有偏技术进步与区域创新空间收敛

Factor Endowment,Partial Technological Progress and Spatial Convergence of Regional Innovation

在我国经济发展模式由要素驱动转向创新驱动的高质量发展背景下,加快要素市场化改革是激发全社会创造力的关键。文章基于CES生产函数构建具有异质性特征的两地区三部门内生增长模型,从理论上分析了要素禀赋差异和有偏技术进步对区域创新空间收敛的影响机理,并从城市层面进行了实证检验。研究发现:要素集聚促进了区域创新,要素禀赋的空间非均衡性导致了区域创新空间差异。我国城市资本和劳动呈互补关系,技术进步方向总体上偏向资本。在有偏技术进步作用下,价格效应引致稀缺要素向发达地区集聚,技术进步方向的非同向性造成创新极化效应大于扩散效应,加剧了我国区域创新空间差距。研究结论为提高区域要素配置效率、促进创新空间收敛提供了重要启示。

Under the background of high-quality development of China's economic development mode from factor driven to innovation-driven,accelerating the market-oriented reform of factors is the key to stimulating the creativity of the society.Based on CES production function,this paper constructs a heterogeneous endogenous growth model of two regions and three sectors,analyzes theoretically the influence mechanism of factor endowment difference and biased technological progress on the spatial convergence of regional innovation,and makes an empirical test at the city level.The findings are as follows:factor agglomeration promotes regional innovation,and the spatial disequilibrium of factor endowment leads to the spatial difference of regional innovation.Urban capital and labor are complementary to each other,and the direction of technological progress is biased to capital as a whole.Under the influence of partial technological progress,the price effect leads to the agglomeration of scarce elements in developed areas,and the non-homogeneity of technological progress leads to the innovation polarization effect greater than the diffusion effect,which exacerbates the regional innovation spatial gap in China.The conclusions provide important implications for improving the efficiency of regional factor allocation and promoting the spatial convergence of innovation.
