Based on China's political governance sys-tem and land system,this paper systematically analyzed the in-ternal logic of the impact of land resource misallocation on car-bon emission efficiency,calculated the carbon emission efficien-cy of 273 cities in China by using Super-SBM model,and then empirically analyzed the impact of land resource misallocation on urban carbon emission efficiency and its mechanism by using panel Tobit model and fixed effects model.The results show that land resource misallocation inhibits the improvement of urban carbon emission efficiency,and this negative effect is more pro-nounced in central and western cities,small and medium-sized cities and resource-dependent cities.Mechanism tests reveal that inhibiting upgrading of industrial structure,distorting fiscal expenditure structure,hindering social responsibility and impe-ding green innovation of enterprise are four important transmis-sion channels.Further analyses indicate that local governments'economic growth target and financial pressure reinforce the in-hibitory effect of land resource misallocation on urban carbon e-mission efficiency,while the green performance assessment mechanism weakens the negative impact.
