Abstract: The harmonious coexistence between man and nature requires efficient use of land resources and development of green economy. From the perspective of the dual constraints of economic growth target and environmental protection target, it is significant to analyze the impact of land resource misallocation on urban green total factor productivity. This paper conducts an empirical study based on the panel data of 284 prefecture cities of China from 2007 to 2019. The findings show that land resources misallocation significantly inhibits the improvement of urban green total factor productivity. After a series of robustness test and endogenous analysis, such as changing explanatory variables, shrinking tail treatment and so on, the conclusions still hold. Specifically, the inhibitory effect of land resource misallocation is realized by promoting urban sprawl and reducing urban green innovation, and the inhibitory effect is more obvious in the central and western cities, non-resource-based cities and medium-sized cities. Further analysis reveals that economic growth target will strengthen the inhibiting effect of land resources misallocation on green total factor productivity, and that strong environmental target constraint will significantly weaken the inhibiting effect of land resource misallocation on green total factor productivity, while the regulating effect of the weak environment target constraint is not significant. Therefore, it is necessary to further promote the market-oriented reform of land factor, build a market-oriented green innovation technology system, strengthen the environmental target constraints of official assessment, alleviate the degree of land resource misallocation, so as to improve the efficiency of urban green development.
