Infrastructure investment plays a key role in steady economic growth. Investment in infrastructure is gradually increasing; however, large-scale infrastructure investment is also associated with efficiency problems and environmental problems, which need to be carefully examined. The entropy weight method and the Super-SBM model are implemented to measure environmental regulation and infrastructure investment efficiency, respectively; and the spatial Durbin model is applied to analyze the influence mechanism and spatial effects of environmental regulation on infrastructure investment efficiency. The results show that spatial agglomeration characteristics exist in both environmental regulation and infrastructure investment efficiency. Besides, environmental regulation can promote infrastructure investment efficiency in general, but it develops an inverted U-shaped relationship as the intensity increases. Lastly, the spillover effects of environmental regulation on infrastructure investment efficiency present a U-shaped relationship. The conclusion is that both environmental regulation and infrastructure investment efficiency in China increased from 2008 to 2020. Besides, moderate environmental regulation is beneficial to infrastructure investment efficiency and restrains spatial spillover, but strict environmental regulation appears to be the opposite. This research expands the literature on environmental regulation and production efficiency and provides a reference basis for formulating effective policies to improve infrastructure investment efficiency from the perspective of the ecological environment.
基础设施投资在稳定经济增长中发挥着关键作用。基础设施投资在逐步增加,但大规模的基础设施投资也伴随着效率问题和环境问题,需要仔细研究。采用熵权法和 Super-SBM 模型分别衡量环境规制和基础设施投资效率,并应用空间杜宾模型分析环境规制对基础设施投资效率的影响机制和空间效应。结果表明,环境规制和基础设施投资效率均存在空间集聚特征。此外,环境规制通常可以促进基础设施投资效率,但随着强度的增加,二者呈现出倒 U 型关系。最后,环境规制对基础设施投资效率的溢出效应呈现出 U 型关系。结论是,2008 年至 2020 年期间,中国的环境规制和基础设施投资效率均有所提高。此外,适度的环境规制有利于基础设施投资效率,并抑制空间溢出,但严格的环境规制则相反。本研究扩展了环境规制和生产效率方面的文献,为从生态环境角度制定提高基础设施投资效率的有效政策提供了参考依据。
