摘要
文章运用空间杜宾模型,度量创新要素集聚及其空间溢出活动对地理邻近城市生产率的影响程度,同时关注政府用于创新支持的公共支出与这种效应的关系。研究结果证明了空间自回归效应的存在,因此传统的OLS方法大大低估了创新要素的集聚效应。研究表明创新要素集聚程度对于城市生产率具有显著贡献,可以有效提升本城市以及周边地区的劳动生产率。政府用于创新支持的公共支出,强化了发达地区的虹吸效应,在促进当地生产率的同时,对周边地区产生了负向影响。
The paper applies the spatial Durbin model to measure the impacts of innovation elements Region agglomeration and their spatial spillover activities on productivity of geographically adjacent cities, and also focuses on the relationship between the government' s expenditure on innovation support and the impacts. The results prove the existence of spatial autoregressive effect, thus the traditional OLS method greatly underestimates the accumulative effect of innovation elements. The study shows that the degree of innovation elements agglomeration has a significant contribution to city productivity, which can effectively promote the productivity of both local and adjacent cities.The government's expenditure on innovation support has strengthened the siphon effectin developed areas, which improves the local productivity, but has had a negative impact on the surrounding areas.
