制度质量与高技术产业集聚——基于面板门槛模型的实证研究

The Institutional Quality and High-tech Industry Agglomeration——An Empirical Research based on Panel Threshold Model

文章从新制度经济学的视角,采用面板数据门槛模型对中国142个城市2001-2017年制度质量与高技术产业集聚水平之间的非线性关系进行了研究,并根据制度质量门槛值进行了分组回归。研究结果发现:由于城市所处的制度质量发展阶段不同,制度质量对高技术产业集聚水平提高的推动作用呈现显著的门槛效应。具体来看:制度质量的提高与高技术产业集聚水平提高之间呈显著正相关;在制度质量的不同发展阶段,制度质量与高技术产业集聚水平之间呈非线性关系;从分区间统计看,中国大部分城市处于高技术产业集聚水平提升的制度质量红利阶段。

Based on the theory of new institutional economics,this paper uses the panel threshold model to study the non-linear characteristics relationship between institutional quality and high-tech industry agglomeration level in 142 cities from 2001 to 2017,and the group regressions are carried out according to the thresholds of institutional quality.The results are found,due to the different stages of the institutional quality of different cities,the institutional quality has a significant threshold effect on the promotion of high-tech industry agglomeration level.Specifically,there is a significant positive correlation between the improvement of institutional quality and the improvement of the level of high-tech industry agglomeration.There is a non-linear relationship between institutional quality and the level of high-tech industrial agglomeration in the different stages of development of institutional quality.From the statistics of partitions,most of Chinese cities are in the stage of institutional quality dividends in which the level of high-tech industry agglomeration is improved.
