摘　　要：再生资源利用的碳减排效应对推动形成适合中国国情的差异化减排路径和实现“双碳”目标具有重大意义。在此背景下,深入探讨和评估再生资源利用的碳减排效应及作用机制,是学界亟待厘清的重要课题。文章作者首先将再生资源对原生资源的替代利用看作是一种环境反污染活动,并构造社会效用函数,基于最优控制理论模型,推导再生资源利用对碳减排效应的影响机制。理论推导结果表明:再生资源利用碳减排效应是否存在取决于再生资源利用过程消耗资源的系数,当再生资源替代减少的碳排放大于再生资源回收利用过程中新消耗资源的碳排放,即再生资源替代减碳的“收益”大于“成本”,此时存在再生资源的碳减排效应。其次,运用2005—2019年中国省级面板数据,实证考察再生资源利用水平对碳排放的综合影响,并进一步开展了作用机制分析、门槛效应检验以及异质性讨论。实证检验结果表明:从总体上看,我国再生资源的利用水平与二氧化碳排放表现为负相关关系,再生资源利用能够有效抑制碳排放强度,再生资源减碳的“收益”是大于“成本”的。从作用机制上看,绿色技术创新效应和产业升级结构效应是再生资源利用影响碳排放的重要作用渠道,再生资源替代可以通过推动绿色技术创新和提升产业结构高级化水平抑制区域碳排放强度。门槛效应检验发现,选取再生资源利用水平和经济发展水平作为门槛变量时,再生资源利用水平在影响碳排放时存在一定门槛效应,超过特定门槛值时再生资源利用的碳减排效应越明显,结果表明再生资源替代与碳减排之间的关系并非线性的。进一步通过异质性分析发现地理区位特征和循环经济发展水平的差异使再生资源利用碳减排效应呈现异质性特征。东部地区(相较于西部地区)、南方地区(相较于北方地区)、�It is of great significance to study the carbon emission reduction effect of renewable resources utilization in promoting the formation of differentiated emission reduction paths suitable for China’s national conditions and achieving the double-carbon target.Against this background,in-depth exploration and assessment of the carbon emission reduction effect and mechanism of renewable resources utilization is an important issue that urgently needs to clarify.This study regards the alternative utilization of renewable resources to primary resources as an environmental pollution-control activity,and constructs the social utility function to derive the influence mechanism of renewable resources utilization on carbon emission reduction based on the optimal control theory model.The theoretical derivation results indicate that carbon reduction effect of renewable resources utilization depends on the coefficient of resources consumption in the process of renewable resources utilization.When the carbon emissions reduced by renewable resources substitution exceed the carbon emissions caused by the new consumed resources during the recycling process of renewable resources,that is,when the benefit of carbon reduction from the renewable resources substitution is greater than the cost,the carbon reduction effect exists.Secondly,using Chinese provincial panel data from 2005 to 2019,this paper empirically examines the comprehensive impact of renewable resources utilization on carbon emissions,and further analyzes the effect mechanism,threshold effects,and heterogeneity.The empirical test results indicate that:(1)Overall,there is a negative correlation between the level of renewable resources utilization and carbon dioxide emissions in China.Renewable resources utilization can effectively inhibit carbon emissions intensity,and the benefit of carbon reduction from renewable resources utilization exceeds the cost.(2)From the perspective of mechanism,green technology innovation and industrial structure upgrading have important inte
