Abstract

Abstract: Hebei's mountainous counties develop ecological industries under dual pressure of fragile ecology and lagging economy, which is not only a demand for realizing national “dual carbon” objectives, but also a strategy for green development. This paper uses panel data of Hebei's mountainous counties from 2010 to 2021 to establish a comprehensive evaluation index system of ecological industrial development and technical innovation, applies bi-directional fixed effect model to verify the direct impacts of technical innovation on ecological industries, constructs a mediation effect model to testify the transmitting mechanism of informatization level and industrial structural upgrade, and applies panel threshold model, taking internet penetration rate as threshold variable, to explore the non-linear impacts and heterogeneity of technical innovation on ecological industries. Technical innovation is positively related to ecological industrial development, suggesting it can largely promote ecological industrial development in Hebei's mountainous counties. Such impacts vary in counties and economic development, most in key ecological function zones and in developed areas. Technical innovation can promote ecological industries in Hebei's mountainous counties through increasing informatization and advancing industrial structural upgrade. As internet penetration rate is rising, technical innovation impacts ecological industries in Hebei's mountainous counties in a non-linear manner of first-constraining-then-promoting. Technical innovation is the core drive to mountainous counties' ecology-economy conflict with its functions limited by areas with positioned functions, economic basis and digital conditions. This paper puts forward suggestions on boosting research and development investment, optimizing technical innovation system, advancing industrial structural upgrade and increasing internet penetration rate so as to promote ecological industries in Hebei's mountainous counties.

Key words: technical innovation, ecological industrial development, informatization level, industrial structural upgrade, Hebei province

摘要： 河北省山区县在生态脆弱与经济滞后的双重挑战下推动生态产业发展，既是落实国家“双碳”目标的必然要求，也是实现区域绿色崛起的战略选择。基于2010—2021年河北省山区县的面板数据，分别构建生态产业发展水平与科技创新水平的综合评价指标体系，通过双向固定效应模型实证检验科技创新对生态产业发展的直接影响，并进一步构建中介效应模型，验证信息化水平与产业结构升级的传导机制，最后利用面板门槛模型，以互联网普及率为门槛变量，探究科技创新对生态产业发展的非线性影响并分析其异质性特征。结果表明：1）科技创新与生态产业发展水平存在正相关关系，即科技创新能够显著促进河北省山区县生态产业发展；2）科技创新对山区县生态产业发展的影响在不同的区县或不同经济发展水平的地区存在差异，促进作用最大的为重点生态功能区和经济发达地区；3）科技创新可以通过提高信息化水平、推进产业结构升级来促进河北省山区县生态产业发展；4）随着互联网普及率的提高，科技创新对河北省山区县生态产业发展的影响呈现出先抑制后促进的非线性特征。结论表明，科技创新是破解山区县“生态-经济”矛盾的核心动力，但其效能受区域功能定位、经济基础与数字化条件约束。因此，提出通过加大科技研发投入、完善区域科技创新体系、推动产业结构升级及提高互联网普及率来促进河北省山区县生态产业发展。
