我国区域创新差异的形成机制研究——基于集聚互动、循环累积与空间关联视角的实证分析

Regional Difference Mechanism of Innovation in China--A Case Study from the Perspective of Gathering Interaction, Cumulative Causation and Spatial Relation

受创新集聚互动的空间报酬递增效应影响，由集聚形成的创新互动是创新发达区域的主要优势所在，并且由于集聚的路径依赖特性，发达区域的创新发展本身还是一个循环累积过程。文章摒弃了仅从要素投入角度分析我国区域创新差异问题的研究传统。通过比较我国区域创新的投入产出差异，及检测我国区域创新发展的循环累积特点，不仅证明了集聚互动、循环累积对我国区域创新差异形成的可能作用；同时还在说明区域创新具有空间组团分布特性的基础上，证明了空间关联因素与我国区域差异形成的可能关系。最后，运用空间计量经济学模型，实证检验了这些因素对我国区域创新差异产生的实际贡献作用。

Innovative interaction formed by the agglomeration can be said that the main advantage of the innovation of developed regions because of the increasing returns in the spatial level from concentrative interaction, and innovation development of developed region is a cumulative causation process as a result of gathering path-dependent. Proceeded from the realization of importance of gathering interaction, the paper abandoned the studying tradition which is only from the perspective of elements put into regional innovation development. With the help of the input-output difference comparison of China＇s regional innovation and the cumulative causation process of regional innovation development, the paper has proved the possible role of gathering interaction and cumulative causation to the China＇s regional innovation differences. By breaking the one-way flowing assumptions of innovation elements, the paper has also proved the role of spatial interaction on the basis of affirming the spatial interdependence in the development of China＇s regional innovation. And finally by using of the spatial econometric models, this paper examines the actual contribution of these factors on the difference of regional innovation.
