Study On Comprehensive Evaluation Of Development Capability Of Expressway Infrastrucure In Provincial-level Administrative Regions

China has attained internationally known achievements for it's developments in expressway infrastructure industry in more than 20 years until present. However, as the difference of development capacity of expressway in each province, the non-equilibrium in the expressway infrastructure industry in different provinces becomes increasingly evident while the size of the nation's expressway infrastructure is increasing rapidly. The non-equilibrium contradiction in expressway infrastructure industry roots in both theory and practice, but more from theory, especially the lack of systematic reasearching on the development capacity of regional expressway infrastructure. At present, the relevant theoretical researches mainly focus on the contribution from expressway infrastructure to the development of national economy and it's sustainable development. Although there are some studies on how to develop the expressway infrastructure from the aspect of it's financing, construction, operation and maintenance, they do not relate the mechanism of regional factors to the development capacity of expressway infrastructure and it's comprehensive evaluation.So the research of comprehensive evaluation on development capability of regional expressway infrastructure is still in the blank.For that reason, the dissertation researches on the development capability of expressway infrastructure from regional perspective.The paper expands around" provincial region", "expressway infrastructure", "development capability" and"comprehensive evaluation". In order to explore the main factors impacted the development capacity and the reasons for forming the difference of development capability of expressway infrastructure in different provices,the paper gives the development capability a comprehensive evaluation based on the analysis of the mechanism of regional factors to the development capability of expressway infrastructure.From the view of difference of development capability of expressway infrastructure,the paper reveals the main reasons for forming the non-equilibrium in expressway infrastructure. For the aim of improving the development capacity of regional expressway and leading the regional expressway infrastructure to develp in a healthy way, the research uses the methods of both normative and empirical analysis. While the qualitative analysis and quantitative analysis methods are used, the reasearch more focuses on qualitative analysis.The basic idea in this paper is using the qualitative analysis and quantitative analysis methods, but more focusing on qualitative analysis, emphasising on theory and application at the same time, more inclineing to theoretical reasearch, between the research methods and results, paying more attention to the rationality of the method.The dissertation is mainly comprised with three parts, the contribution mechanism of expressway infrastructure to regional economic development, the development capacity of expressway infrastructure in provincial-level administrative regions, the comprehensive evaluation on the development capacity of expressway infrastructure.With the forming process of expressway infrastructure for an entry point, the first part breaks the expressway infrastructure into flow assets and permanent assets from the view of assets and makes a scientific definition of their connotations. After that, this part researches on the contribution mechanism of both flow assets and permanent assets of expressway infrastructure to economic development along the expressway chiefly.The second part, including chapter 3 and 4, studies the development capacity of expressway infrastructure in provincial-level administrative regions from the qualitative point of view. Based on making a scientific connotation definition of development capacity of expressway infrastructure, this part firstly breaks development capacity of expressway infrastructure down into financing, construction, operation and maintenance of such sub-capacity. Secondly, this part researches the mechanisms of some factors in provincial-level administrative regions, such as level of economic development, local government's decision-making, management system and the natural environment, to the sub-capacity of expressway infrastructure. Thirdly, based on the prerequisite of characterizing the connotation of development capacity of expressway infrastructure, the evaluation specific indices for comprehensive evaluation of expressway infrastructure is put forward in this part. Lastly, using relevant economic theory, the optimal investment scale of regional expressway infrastructure based on development capacity of expressway infrastructure is derived, which is one important components of this part.The third part researches the development capacity of expressway infrastructure from the perspective of qualitative and empirical, including chapter 5 and 6. Firstly, using the relevant theory of comprehensive evaluation as a guide and based on the attribute of the development capacity of expressway infrastructure, the index system for comprehensive evaluation, formed of 4 hierarchical levels, is constructed in. this part. Secondly, from two aspects, the development level and development potential of the expressway infrastructure in provincial-level administrative region, the factor analysis method is used to analyze the development capacity of expressway infrastructure in most provinces in China. The quantitative study, based on comprehensive evaluation indexes, proves the research conclusions from qualitative perspective. At last, according to the related research conclusion from both qualitative and quantitative way, some suggestions are put forward to government administration for their decision-making.
