城市紧凑度与区域创新能力——以江苏省为例

The City Compactness With Innovation Ability:A Case Study of Jiangsu Province

城市规划作为城市发展过程中不可避免的问题,成为影响城市长远高效发展的重要因素。而创新能力作为城市竞争力的内在表现,也日益成为城市向前发展的重要推手。基于此背景,本文首先从理论机制层面分析城市紧凑度与创新能力之间是如何发生作用的,然后构建衡量城市紧凑度的指标体系,并通过极值熵值法对江苏省各城市的城市紧凑度进行测度,最后利用双向固定效应回归方法对城市紧凑度与创新能力发生作用的理论机制进行实证检验。结果显示:城市紧凑度对创新能力具有非常显著的影响作用,城市紧凑度的提高可以促进创新能力的增加。因此政府应该采用紧凑型城市规划,提高城市紧凑度进而推动创新能力的提升。

As an inevitable problem in the process of urban development,urban planning has become an important factor affecting the long-term and efficient development of cities. As the internal performance of the city’s competitiveness,innovation ability has increasingly become an important driver of the city’s development. Based on this background,this article first from the aspect of theoretical mechanism analysis between urban compactness and the innovation ability is how to interact,then build the measure index system of urban compactness,and through the mechanism of entropy value method to measure urban compactness of the cities in Jiangsu province. Firstly,the use of bidirectional fixed effects regression method on the compact city with innovation ability the theoretical mechanism of empirical test,this paper analyzes how city compactness and innovation ability function from the theoretical mechanism level. Then,this article constructs index system to measure city compactness. Meanwhile,this article measures city compactness in Jiangsu province by the extremum entropy method. At last,this article uses the bidirectional fixed effects to test the mechanism of ctiy compactness and innovation ability. The results show that the city compactness has a significant effect on the innovation ability,and the improvement of the city compactness can promote the increase of the innovation ability through the knowledge spillover effect and the increase of human capital and social capital. Therefore,compact urban planning is adopted to effectively improve the city’s compactness and promote the improvement of innovation capacity.
