数字经济赋能生态产品价值实现机制研究

The Value Realization Mechanism of Digital Economy Enabled Ecological Products

作为新质生产力的重要载体,数字经济是落实“两山”理念,持续赋能生态产品价值实现的重要驱动力。本研究采用2011—2021年中国245个地级市面板数据,引入“金山银山”系统与“绿水青山”系统的耦合协调度作为生态产品价值实现的代理变量,从“有为政府”和“有效市场”两个维度实证评估了数字经济对生态产品价值实现的影响效应及渠道机制。结果表明:数字经济对生态产品价值实现的赋能效应显著,在经过一系列稳健性检验后该结论依然成立;异质性检验表明,数字经济对生态产品价值实现的赋能效应存在区域异质性,呈现出东、中、西部皆为正向影响的格局且对资源型城市的影响效应更加显著;从作用机制看,数字经济分别通过“有为政府”的环保治理优化效应和“有效市场”的科技创新驱动效应两条路径赋能生态产品价值实现。基于此,本研究提出结合不同地区资源禀赋,加强数字基础设施建设赋能生态产品价值实现等政策建议。

As an important carrier of new quality productive forces,the digital economy is an important driving force for implementing the concept of"two mountains"and continuously enabling the realization of the value of ecological products.Based on the panel data of 245 prefecture-level cities in China from 2011 to 2021,this study introduces the coupling and coordination degree of"two mountains"conversion as the proxy variable for the value realization of ecological products,and empirically analyzes the impact effect and mechanism of digital economy on the value realization of ecological products from the two dimensions of"a well-functioning government"and"an efficient market".The results show that the enabling effect of digital economy on the value realization of ecological products is significant,and the conclusion is still valid after a series of robustness tests.The heterogeneity test shows that the enabling effect of digital economy on the realization of the value of ecological products has regional heterogeneity,showing a positive impact pattern in the East,Middle and West,and the impact effect on resource-based cities is more significant.From the perspective of action mechanism,digital economy is enabled to realize the value of ecological products through two paths:the optimization effect of environmental protection governance of"a well-functioning government"and the driving effect of scientific and technological innovation of"an efficient market".Based on this,this study proposes policy suggestions such as strengthening the construction of digital infrastructure in combination with the resource endowment of different regions to realize the value of ecological products.
