创新驱动下城市产业生态转型升级研究——基于城市空间杜宾模型的实证

由工业化初期向工业化中后期转变的关键时期,我国的产业增长方式将经历从资源和资本驱动转变为创新驱动的过程。以创新为驱动力,延长产业价值链,实现产业结构的合理化与高度化,已然成为研究的重点。本文基于空间杜宾模型,利用2002-2017年272个城市的面板数据,研究了城市创新驱动与产业转型升级的关系,得出了以下结论：城市产业转型具有正的空间溢出效应,创新驱动能显著提升城市产业转型升级的水平,并且城市的创新驱动水平对周边城市的产业转型升级有明显的促进作用。进一步研究,发现城市群的出现能有效加强城市创新驱动对周边城市产业转型升级的促进作用。本文通过替换指标、邻接关系矩阵替换、分组检验等方式进行稳健性检验,实证结果保持稳健。

Research on urban industrial ecological transformation and upgrading driven by innovation -- an empirical study based on urban space durbin model

from the early stage of industrialization to the middle and late stage of industrialization, China"s industrial growth mode will experience the transformation from resource and capital driven to innovation-driven process. It has become the focus of research to take innovation as the driving force, extend the industrial value chain, and realize the rationalization and upgrading of industrial structure. Doberman model of this article is based on space, using the panel data of 272 cities in 2002-2017, to study the driving force of urban innovation and industry transformation and upgrading, draws the following conclusion: positive spillover effects of space city industry transformation, innovation drive can significantly enhance the level of city industry transformation and upgrading, and the city"s innovation drive level of the surrounding city industrial transformation and upgrading has obvious role in promoting. Further research shows that the emergence of urban agglomeration can effectively strengthen the role of urban innovation drive in promoting the industrial transformation and upgrading of surrounding cities. In this paper, the robustness test is carried out by means of substitution index, adjacency matrix substitution and grouping test, and the empirical results remain robust.
