Abstract
Rapid urbanization has provided a strong impetus for the economic growth of China, but it has also caused many problems such as inefficient urban land use and environmental pollution. With the popularization of the concept of green and sustainable development, the Environmental-Social-Governance (ESG) assessment concept is widely accepted. The government and residents are paying more and more attention to environmental issues in urban development, and environmental protection has formed an important part of urban development. In this context, this study takes 26 cities in the Yangtze River Delta as examples to build an evaluation system for urban land-use efficiency under green development orientation. The evaluation system takes into account the inputs of land, capital, labor, and energy factors in the process of urban development. Based on emphasizing economic output, the social benefits and undesired outputs brought about by urban development are taken into account. This paper measures urban land use efficiency by the super-efficiency SBM model, and on this basis, analyses the spatial-temporal evolution characteristics of urban land-use efficiency. Further, this paper measures urban land use efficiency without considering undesired outputs and compares the two evaluation methods. Again, the comparison illustrates the rationality of urban land use efficiency evaluation system under green development orientation.
Highlights
In recent years, the whole world has been in a rapid wave of urbanization [1]
The urban land useefficiency without considering the undesired outputs and the urban land use- efficiency considering the expected outputs have extremely similar development trajectories, and the urban land-use efficiency considering the undesired outputs is generally lower than the urban land use efficiency without considering the undesired outputs
From the results, when we control the cross-section after effect and time effect, all of the regression coefficients is more than 5% of the significant level is negative, it shows that in the Yangtze River Delta urban agglomeration and the three provinces, within the scope of the urban land use efficiency is conditional β convergence, that said, Yangtze River Delta urban agglomeration and the three provinces of urban land-use efficiency
Summary
The whole world has been in a rapid wave of urbanization [1]. In the long term, this wave of urbanization still has strong growth potential. As the largest developing country in the world, China has made remarkable achievements in the process of urbanization in the past decades. Energy consumption and industrial pollutant emission increased sharply [8,9] Such high input, high consumption, and high emission economic development mode lead to low urban land-use efficiency, serious energy waste, and great pressure on the ecological environment, which is not conducive to the sustainable development of China’s social economy [10,11]. To achieve sustainable development of the national social economy and land management, it is very important to improve urban land-use efficiency [13]
