基于哈肯模型下“才富”与“财富”对绿色技术创新的共轭效应研究

A study on the covariate effects of talent and wealth on green technology innovation based on the Harken model

摘要:

以绿为首，低碳先行的发展模式离不开“才富”与“财富”的创新赋能。选取2007—2020年我国30个省份样本数据，利用熵权法测度科技人才集聚与绿色金融发展水平，识别二者间共轭关系，判断共轭效应存在性，并利用哈肯模型将其量化纳入回归模型，分析对绿色技术创新水平的作用。最后，探析影响共轭效应水平的因素以期提升绿色创新赋能。主要研究结论如下：（1）科技人才集聚与绿色金融发展两系统内部相互促进且各自直接及以对方为中介间接促进绿色技术创新，即存在共轭效应。（2）异质性分析发现，共轭效应对绿色技术创新水平的赋能作用在中部和信息化水平高的地区更明显；而环境规制水平高、人口规模小的地区赋能作用却难以发挥。（3）绿色经济发展水平、交通水平、外商直接投资对共轭效应呈现积极作用；能源结构的贡献显著为负；城镇化水平、环境规制水平存在不显著正影响。从“才富”与“财富”两大要素非独立性角度，本文回答了二者在共轭驱动下能否赋能绿色技术创新这一问题，为各省兼顾“聚才”与“积财”，实现绿色低碳提供经验证据与政策参考。

Abstract:

The development model of green as the first, low-carbon first cannot be separated from the innovative empowerment of "talent wealth" and "wealth". We select the sample data of 30 provinces in China from 2007 to 2020, measure the level of scientific and technological talent concentration and green financial development using entropy weight method, identify the conjugate relationship between the two, determine the existence of conjugate effect, and quantify it into the regression model using Harken's model, and analyze the role of the level of green technological innovation. Finally, the factors affecting the level of conjugate effect are explored with a view to enhancing green innovation empowerment. The main conclusions of the study are as follows: (1) The two systems of scientific and technological talent pooling and green financial development promote each other and each of them directly and indirectly promotes green technological innovation through the intermediary of the other, i.e., there is a conjugate effect. (2) Heterogeneity analysis reveals that the enabling effect of the conjugate effect on the level of green technological innovation is more obvious in the central region and regions with high informationization level, while the enabling effect is difficult to be exerted in regions with high level of environmental regulation and small population size. (3) The level of green economy development, the level of transportation, and foreign direct investment have a positive effect on the covariate effect; the contribution of energy structure is significantly negative; the level of urbanization and the level of environmental regulation have a non-significant positive effect. From the perspective of the non-independence of the two elements of "talent and wealth" and "wealth", this paper answers the question of whether they can empower green technological innovation under the conjugate drive, and provides a good solution for the provinces to take into account both "talent accumulation" and "wealth accumulation". This paper provides empirical evidence and policy references for provinces to realize low carbon greening by taking "talent accumulation" and "wealth accumulation" into account.
