中国建筑业高质量发展水平测度、区域差异及分布动态演进

Measurement of the High-Quality Development Level,Regional Disparity and Distribution Dynamic Evolution of China’s Construction Industry

以“新发展理念”为基础,结合建筑业自身发展特征,从8个维度构建了中国建筑业高质量发展水平综合评价指标体系,利用熵值法测度了2012—2021年30个省份的建筑业高质量发展水平,进一步利用Dagum基尼系数及其分解方法和Kernel密度估计法对建筑业高质量发展水平的区域差异和非均衡性进行分析。结果表明,中国建筑业高质量发展水平较低,测算结果均值处在0.122 9~0.586 0之间;基尼系数整体上涨了5.2%,说明我国建筑业高质量发展存在区域差异,且差异正逐年增大;全国及区域的建筑业高质量发展水平非均衡性显著,且东西部存在极化现象。

On the basis of the“New Development Concept”,combined with the development characteristics of the construction industry,a comprehensive evaluation index system has been constructed for the high-quality development level of China’s construction industry from eight dimensions.The entropy method is adopted for the measurement of the high-quality development level of the construction industry in 30 provinces from 2012 to 2021,followed by a subsequent analysis of the regional disparity and imbalances in the high-quality development level of the construction industry by using the Dagum Gini coefficient and its decomposition method,as well as the kernel density estimation method.The results show that the high-quality development level of China’s construction industry is relatively low,with estimated values ranging from 0.1229 to 0.5860;the overall Gini coefficient has increased by 5.2%,which indicates that there are regional disparity in the high-quality development of China’s construction industry,with the differences increasing year by year;there is a significant imbalance in the high-quality development level of the construction industry across the whole country and regions,with its polarization in the eastern and western regions of the country.
