| 为评估当前中国建筑业的投入产出效率,利用信息熵和交叉效率分析建筑业效率并排序是一种有效手段。通过最小化当评省份自评效率与他评效率间的距离熵,以及最小化所有省份自评效率与他评效率间的距离熵两个角度,确定各省份及区域建筑业的效率发展水平,并进行分析和排序。结果表明：用信息熵集成交叉效率可有效区分各省份及区域建筑业的效率发展水平,提供一个客观合理的建筑业效率排名。中国建筑业呈现出较强的区域性特点,不同区域间建筑业的发展水平呈现出不均衡的态势,总体表现出长江中部地区效率高,沿海地区效率次之,而西北、东北部地区效率较低的特点。 |

| To assess the current efficiency of China"s construction industry, the use of information entropy and cross-efficiency to analyze and rank the efficiency of the construction industry is an effective means. By minimizing the distance entropy between individual provincial self-assessed efficiency and peer-efficiency, as well as minimizing the distance entropy between self-assessed efficiency and peer-efficiency across all provinces, ascertain the efficiency development levels of each province"s and each region"s construction industry, and conduct analysis and ranking. The results indicate that integrating cross-efficiency with information entropy can effectively differentiate the efficiency development levels of the construction industry in various provinces and regions. This approach provides an objective and reasonable basis for the efficiency ranking of the construction industry. The construction industry in China exhibits strong regional characteristics, with significant disparities in development among different areas. Overall, the central Yangtze region demonstrates the highest efficiency, followed by the coastal areas, while the northwest and northeast regions show lower efficiency levels. |
