结合PCA改进AHP-TOPSIS法对环京津四小城市建筑业竞争力评价研究

Competitiveness of Four Small-sized Cities around Beijing and Tianjin:an Improved AHP-TOPSIS Approach in Connection with PCA

从"国际竞争力方程"中"竞争力资产"和"竞争力过程"两个方面出发,选取了结合PCA (主成分分析法)改进的AHP-TOPSIS评价法,从产值规模、产业结构、建筑业企业实力、建筑业材料消耗情况、建筑业产值机构、建筑业发展潜力、建筑企业生产效益、建筑业经济效益八个方面32个细化指标,建立了区域建筑业竞争力指标评价体系。结合2017年相关数据,对4个环京津中小城市与北京、天津建筑业竞争力进行横向对比分析,找出环京津地区四个小城市建筑业发展的优势与不足,并为环京津四小城市建筑业未来发展提出了合理性建议。

According to the"competitive assets"and"competitive process"in the"international competitiveness equation",the present study used the improved AHP-TOPSIS evaluation method in connection with PCA to establish competitiveness indexes for regional construction industry.The evaluation system includes32specific indexes in8aspects.Based on the related data of2017,the study studied the competitiveness of4small-sized cities around Beijing and Tianjin to evaluate their construction industry,and offered suggestions for the industry's future development.
