【摘要】：依据广义的绿色产业内涵,通过信息显著性差异与信息冗余分析定量筛选指标,建立了包括绿色生产指标层、绿色生态环境指标层、绿色消费方式指标层的大连市绿色产业评价指标体系。本文的创新与特色一是通过负载系数大小差异进行信息显著性分析,删除负载系数小、对综合评价结果影响弱的指标。克服了现有研究先进行相关分析剔除冗余指标,再利用负载系数大小差异筛选出反映信息显著性大的指标的弊端。事实上,指标间较高的相关性是计算负载系数的必要前提。因此,利用负载系数筛选指标前是不可进行指标的相关分析降低指标间的相关性的。二是通过结合专家知识经验辨析指标的实际含义,仅对反映信息可能重复的指标使用相关分析,剔除同指标层内相关系数较大的两个指标中反映指标层信息能力相对较弱的指标。克服了仅仅通过相关系数不能准确衡量指标间信息重复程度的弊端。研究结果表明,最终建立的指标体系通过25.68%的指标反映了97.09%的原始信息。通过与同类的指标体系进行对比,对大连市绿色产业评价指标体系的合理性做了进一步的分析。
[Abstract]:According to the connotation of green industry in a broad sense, the index layer of green production index and the index layer of green ecological environment are established through the quantitative screening index of information salience difference and information redundancy analysis. The innovation and characteristic of this paper is to analyze the significance of information through the difference of load coefficient, and delete the load coefficient is small. In order to overcome the disadvantages of the existing research on eliminating redundant indexes by correlation analysis, and then using the difference of load coefficient to screen out the indexes that reflect the great significance of information, we can overcome the disadvantages of the indexes with weak influence on the comprehensive evaluation results. In fact, A high correlation between the indicators is a necessary prerequisite for calculating the load factor. The correlation analysis of indicators can not be carried out before the load coefficient is used to screen the indicators. Secondly, by analyzing the actual meaning of indicators by combining expert knowledge and experience, we only use correlation analysis for indicators that reflect the possible repetition of information. The index which reflects the relatively weak information ability of the index layer is eliminated from the two indexes with larger correlation coefficient within the same index layer. It overcomes the shortcoming that the degree of information repetition between the indicators can not be accurately measured by the correlation coefficient alone. The results show that, The established index system reflects the original information of 97.09% through the index of 25.68%. The rationality of the evaluation index system of green industry in Dalian is further analyzed by comparing the index system with the similar index system.
