Green Development Level Evaluation of Urban Engineering Construction in the Mid-Low Reaches of Yangtze River, China

Abstract

Urban engineering construction represents the physical construction aspects of urban areas and is recognized as an important carrier for green city. With the rapid pace of urbanization, the conventional construction mode is no longer sufficient to meet the requirements of achieving a beautiful China. As a result, promoting the green development for urban engineering construction (GDUC) has become an vital initiative to facilitate the green transformation and sustainable development of cities. This paper adopts the comprehensive evaluation model and super-efficiency slacks-based measure model to evaluate and demonstrate the status and efficiency of GDUC in the Mid-Low reaches of Yangtze River (MLRYR) from 2011 to 2020. The results show a consistent increase in both the status and efficiency of GDUC in the MLRYR during the study period, with a more noticeable changes observed in status than efficiency. In addition, the development of status exhibits distinct phases on the time scale, while the development of efficiency shows prominent differences on the spatial scale. The level stages and significant factors of GDUC are analyzed through a comprehensive evaluation considering two dimensions: status and efficiency. Given these results, in order to further promote the level of regional GDUC in China, several countermeasures and suggestions are put forward from the following aspects: perfecting the status of urban physical construction, enhancing the efficiency of engineering economic production, and strengthening communication and collaboration within urban regions.
