摘　　要：为深入探究土地资源错配的碳排放效应及区域差异,基于2009-2020年中国省份面板数据(不含西藏自治区及港澳台地区数据),通过构建系统GMM模型和双向固定效应模型分析土地资源错配对碳排放的动态影响效应及机制。结果表明:①土地资源错配显著促进碳排放量,土地资源错配程度每提高1%,碳排放量将显著增加0.462%,且影响具有长期性,滞后一期、二期和三期的影响效应分别通过了5%、1%和5%水平检验。②产业结构合理化、高级化在土地资源错配影响碳排放中起中介作用。③与我国东部、中部地区相比,土地资源错配对西部地区碳排放量的促进作用更显著。④市场分割在土地资源错配与碳排放量之间起正向调节作用,其调节效应呈商品市场>资本市场>劳动力市场的特征。因此,建议地方政府克服“以地谋发展”的短视行为,减少过度或错误干预土地资源配置,推动地区产业结构升级,并充分发挥市场机制在土地资源配置中的决定性作用。To explore the impact of land resource misallocation on carbon emissions and its regional variations,this study constructed a system GMM model and a two-way fixed effect model based on the panel data from Chinese provinces from 2009 to 2020(excluding data from Xizang Autonomous Region,Hong Kong,Macao and Taiwan),and analyze the dynamic effects of land resource misallocation on carbon emissions and the underlying mechanism.The results show that:(1)Land resource misallocation significantly increases carbon emissions.A 1% increase in the degree of land resource misallocation leads to a 0.462% rise in carbon emissions in the long run.The impact effects of the first,second,and third lag periods are significant at 5%,1% and 5%,respectively.(2)The rationalization and upgrading of industrial structure serve as mediating factors in the relationship between land resource misallocation and carbon emissions.(3)Compared to the eastern and central regions,the role of land resource misallocation in promoting carbon emissions in the western region is more significant.(4)Market segmentation plays a positive moderating role between land resource misallocation and carbon emissions,with the moderating effects ranked in the following order:commodity market>capital market>labor market.Therefore,local governments should avoid the short-sighted practice of‘using land for development’,reduce excessive or inefficient interventions in land resource allocation,promote the upgrading of regional industrial structures,and fully leverage the decisive role of market mechanism in the allocation of land resources.
