The pollution caused by the production activities in the construction industry has become one of the three major pollution sources in China.To reduce the pollution caused by the construction enterprises in the production process is the primary solution to achieve ecological civilization and realize the sustainable development of the society.By intensifying the Study on ecological efficiency,the current state of pollution within the industry could be better understood,thus offering both theoretical and practical solutions to change the mode of production,improve the production efficiency and to formulate relevant policies.Based on mentioned above,the ecological efficiency of construction industry in Chinese 30 provinces during 2003-2013 were calculated by using the super efficiency DEA model.Based on the convergence and divergence trend analysis of ecological efficiency in the national and three regional levels,the construction industry convergence is analyzed as follow:1.During the research period,ecological efficiency in most of cities and provinces failed to achieve the effective state of ecological efficiency owing to the huge gap between the efficiency and decision making units of the most effective production frontiers.As for individual region,the ecological efficiency in the eastern region is generally higher than the central and western regions,while the lowest ecological efficiency situated in western region.2.The convergence analysis shows that the ecological efficiency of construction industry in China has absolute convergence and beta convergence.However,after adding the control variables,the paper shows that the conditional convergence exists in the ecological efficiency of China's construction industry,i.e.there is decreasing trend as the time goes by.Itmeansthattheeasternregion should strengthen the use of resources,improve the efficiency of the allocation of the construction industry,so that to achieve a better level of management.As for the central and western regions,the authorities should narrow down the gap of technology and other aspects between ecological efficiency,which is conducive to the further development of the industry.Besides,while maintaining the ecological efficiency stable,it is suggested that the industry improve its own efficiency with the purpose of achieving the overall optimal ecological efficiency in domestic construction industry.
