Research On The Evaluation Of Servitization Level Based On Grey Slope Correlation

The research of servitization is an important and forward-looking topic in the development strategy of manufacturing enterprises and urban industrial upgrading strategy,which involves the intersection between enterprise strategic management,geo economics,political economy and so on.The research on industrial conditions and development level of servitization is the basic problem in empirical researches of servitization and the primary combination point of theoretical and empirical research.The result of servitization evaluation provides important and basic information for formulating the development strategy of regional manufacturing servitization.Due to limitations of the input-output table,the evaluation of industry-related conditions for servitization in specified city is one of the most difficult issues.At the same time,there are many shortcomings in the evaluation index system and the evaluation method for the comprehensive service level of enterprises due to the problem complexity,insufficient data and mixed information.Based on previous theoretical researching results,this paper put forward using grey correlation degree and value-added growth rate to evaluate industrial correlation and industrial relative growth in specified city and develop the grey slope correlation degree in order to solve the result instability problem in earlier model,by which the lack of analysis tools on industry-related condition for servitization of specified city is filled.The comprehensive index system of evaluating manufacturing enterprises' service level is established through the integration of relevant researches and the improved slope correlation degree is extended and used in calculating the weight assignment vector of the grey comprehensive evaluation method.Finally,the comprehensive evaluation system is taken to analysis the industry-related conditions and actual development level of the major cities of Hu-Ning-He Region,through which the overall characteristics and horizontal distribution of regional industrial relations and servitization level are preliminarily analyzed.
