摘　　要：本文以2009—2018年沪深两市A股制造业企业作为研究对象,利用双重差分法研究了固定资产加速折旧政策对企业碳排放的影响研究。首先,在控制其他条件不变的情况下,通过排除混杂效应,使用PSM-DID估计、安慰剂检验以及其他稳健性检验,发现固定资产加速折旧政策和企业碳排放之间存在显著的负向关系。其次,加速折旧政策通过投资规模、投资结构与技术创新能产生碳减排的效应。最后,加速折旧政策具有一定的异质性。加速折旧政策对高污染行业企业、高科技行业企业、非亏损企业以及高融资约束企业的碳减排作用更大。本文证实了企业采用固定资产加速折旧政策带来的减排效应,为税收优惠政策降低企业碳排放提供了微观证据,也为中国实现“双碳”战略提供了政策启示。Based on a sample of listed industrial enterprises of A-share in Shanghai and Shenzhen from 2009 to 2018,this paper used the Difference-in-Difference Model as the method for empirical research to explore the effects of the policy of accelerated depreciation of fixed assets on carbon emissions.The research conclusions are as follows:In the case of other conditions are controlled,by excluding hybrid effect and using PSM-DID model estimation,Placebo Effect and other Robustness Tests,this paper finds the relationship between the policy of accelerated depreciation of fixed assets and carbon emissions is negatively correlated.Then,this paper proves that the policy of accelerated depreciation of fixed assets has a significant negative influence on carbon emissions through affecting corporations’size of investment,investment structure and technological innovation.Finally,there exists different heterogeneity of the policy of accelerated depreciation of fixed assets,corporations in high polluting industries,corporations in high-tech industries,non-defective corporations and corporations with higher financial constraints have significant effects in cutting carbon emissions.This paper implies that the policy of accelerated depreciation of fixed assets in corporations claiming for the effects of emission reduction,supplying the microscopic evidence of tax incentives in reducing carbon emissions in corporations and further putting forward policy inspirations for implementation of the national strategy of Carbon Peak Carbon Neutrality.
