摘要:

以“宽带中国”试点城市的推行作为政策冲击,使用多期三重差分模型研究数字基建水平是否降低了省际行政边界地区企业的污染排放,并探究两者间的作用机制。研究发现,数字基建水平能够抑制边界地区企业污染排放,该结果经过一系列稳健性检验后依然成立。机制分析结果表明,数字基建水平通过发挥内部资源效应和外部监管效应抑制边界地区企业排污,倒逼企业绿色转型,并且具有对地理屏障的突破效应。异质性检验结果表明,对于非高科技企业或处于资源型城市边界地区的企业而言,数字基建的减污效果更加显著。文章拓展了边界效应及数字基建的环境效益研究,为促进边界地区高质量发展提供了经验证据和思路启示。

Abstract:

Taking the implementation of the pilot cities of "Broadband China" as a policy shock, and taking the inter-provincial border counties and non-inter-provincial border counties as the treatment group and the control group, a multi-period triplet difference model was used to study whether the level of digital infrastructure reduced the pollution emissions of enterprises in the inter-provincial administrative border areas, and to explore the mechanism of action between the two. The research finds that compared with the central area, enterprises in the border area have more severe pollution emissions. The level of digital infrastructure has an inhibitory effect on this effect. This result still holds after a series of robustness tests. The results of the mechanism analysis show that the level of digital infrastructure restrains the pollution discharge of enterprises in border areas by exerting the internal resource effect and the external regulatory effect, and forces enterprises to undergo green transformation, promoting the sustainable development of enterprises. The heterogeneity test results show that for non-high-tech enterprises and those located in the boundary areas of resource-based cities, the pollution reduction effect of digital infrastructure is more significant. This article expands the research on boundary effects and the environmental benefits of digital infrastructure, providing empirical evidence and inspiration for solving the problem of unbalanced regional environmental development in China and promoting high-quality development in boundary areas.
