Regional Difference Mechanism of Innovation in China——A Case Study from the Perspective of Gathering Interaction,Cumulative Causation and Spatial Relation
从集聚互动和累积因果视角，利用中国区域创新的投入产出差异比较，证明了集聚互动和累积因果对区域创新差异的作用，并通过空间计量模型检验了这些因素的实际贡献。
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.
