Comparison and analysis of influencing factors on carbon emission efficiency of construction industry in Bohai Rim Economic Circle and Yangtze River Economic Belt
In order to explore the carbon emission efficiency of the Bohai Rim Economic Circle and the Yangtze River Economic Belt from the perspective of the construction industry,and realize the transformation from high carbon to low carbon in the two regions,16 provinces and cities in the Bohai Rim Economic Circle and the Yangtze River Economic Belt were taken as the research objects by means of SBM-DDF model,Tobit regression and other methods.The spatial and temporal pattern of carbon emission efficiency of construction industry in the two regions during 2010-2021 and its influencing factors were compared and analyzed.The results showed that the carbon emission efficiency of the construction industry in the Bohai Rim Economic Circle was lower than that in the Yangtze River Economic Belt,and the growth rate of the Bohai Rim Economic Circle was slower.As a whole,the median of the two regions showed an upward trend,the peak of the nuclear density curve shifted upward,and the carbon emission efficiency of the construction industry showed an overall growth trend.The characteristics of"double peaks"of carbon emission efficiency of construction industry in Bohai Rim Economic Circle were more obvious,and the regional differences of carbon emission efficiency of construction industry were more significant.The carbon emission efficiency of construction industry in the Bohai Economic Circle had strong differentiation characteristics.The economic circle around the Bohai Sea belonged to the internal and external coordinated development mode of urbanization level and production level.The carbon emission efficiency of the construction industry in the Yangtze River Economic Belt belonged to the development mode dominated by the external influence of economic development level and residents'consumption level.Residents'consumption level was an important factor common to the two regions,but it had a more significant effect on the Yangtze River Economic Belt.
