基于正态云模型的广东省港口产业发展水平综合评价

Comprehensive Evaluation on the Level of the Development of Port Industry in Guangdong Province Based on Normal Cloud Model

摘要:

为解决广东省港口产业发展水平评价过程中存在的模糊性与随机性问题,先从港口产业发展规模、效率、潜力和结构四个方面构建由14个指标组成的港口产业发展评价体系,应用正态云模型方法,再对反映广东省港口产业发展水平的14个指标进行单因子评价,找出其发展存在的问题,最后结合熵权法对港口产业总体发展水平进行评价,揭示其发展水平的演变状况。从单因子隶属度分析表明,广东省港口产业存在着劳动力、固定资产投入不足、资金周转效率低及临港工业建设缓慢等问题。从综合隶属度分析表明,广东省港口产业总体发展呈波动上升趋势,2012-2013年由低水平快速发展到高水平,2014-2015年回落到一般水平,2016年再次快速发展到高水平,并超过了2013年的发展水平。

Abstract:

In order to solve the problem of fuzziness and randomness in the evaluation process of Guangdong port industry development level, the port industry development evaluation system composed of 14 indexes is constructed from four aspects of the scale, efficiency, potential and structure of the port industry development, and the normal cloud model is applied to reflect the development of the port industry in Guangdong province. The 14 indexes of the flat are evaluated by single factor, and the problems of its development are found. Finally, the overall development level of the port industry is evaluated by entropy weight method, and the evolution of its development level is revealed. From the single factor membership analysis, it shows that there are some problems in port industry in Guangdong Province, such as labor force, insufficient investment in fixed assets, low efficiency of capital turnover and slow construction of port industry. From the analysis of the comprehensive membership degree, the overall development of the port industry in Guangdong shows a fluctuating trend, which has developed from a low level to a high level in 2012-2013 years and 2014-2015 years back to the general level. In 2016, it was rapidly developed to a high level and exceeded the level of development in 2013.
