Abstract:

An evaluation index system was established based on the green development and its efficiency in the construction industry.The static and dynamic efficiencies of green development in the construction industry at the national and provincial levels were estimated using the super efficiency SBM-ML model from 2008 to 2021. The results demonstrate that the static efficiency of green development in the construction industry in China is fluctuant rising. The efficiency value is greater than 1 for nine years. This implies that the green development in the construction industry is relatively effective. The green development efficiency in the construction industry has increased by an average of 1.7% annually, but the stability of dynamic efficiency in different years needs to be improved. The static efficiency of green development in the construction industry in each province shows a distribution of "high in the southeast and low in the northwest", and the efficiency value in each province shows an obvious differentiation of "high, medium and low". While there are fluctuations in the dynamic efficiency levels of green development in the construction industry in each province, there is no obvious manifestation of specific geographical distribution patterns. Through analyzing the calculation results, relevant suggestions are put forward from the aspects of policies and enterprises to optimize the green development efficiency and promote the high-quality development in the construction industry.

Key words: construction industry, green development efficiency, super efficiency SBM-ML model, evaluation, optimization
