“…From the perspective of current environmental protection practices in China, local governments mainly formulate and implement EG policies (Pan and Tang, 2021;Wang et al, 2021), environmental audits (Patriarca et al, 2017;Cao et al, 2022) and EGI (Basoglu and Uzar, 2019;Li and Ramanathan, 2020) to improve environmental quality, and achieved certain effects (Xiong et al, 2020;Jiang et al, 2020). However, some scholars pointed out that due to imperfect legal systems (Moshiri and Daneshmand, 2020), the unreasonable allocation of fiscal environmental protection expenditures (López et al, 2011), the existence of corruption Zhao et al, 2022) and spatial spillover effect (He et al, 2018;Zhao et al, 2021), the EG measures implemented by local governments cannot effectively reduce pollution emissions.…”
