Research On Competitiveness Evaluation Of Highway Listed Companies Based On ESDA

The highway occupies an important position in the social and economic development.Highway business companies breaking the limitations of traditional investment and financing push the highway construction management to the market.China's highway business is the product of market economy and the result of reform and exploration in the process of China's planned economy to the market economy.The research on the competitiveness of highway enterprises is only studied from the general statistical method,ignoring the influence of location factors and the change of spatial competitiveness.The theoretical basis of this paper mainly includes the theory of competition,the theory of spatial competition,the expansion of spatial competition theory.Based on the theories and the induction analysis of highway company competitiveness influencing factors,this paper puts forward theoretical index system of highway company competitiveness evaluation.First of all,this paper summarize the basic theory and the form the highway listed company competitiveness evaluation index system.The factor analysis is used to classify the indicators,and get the scores of each factor,which can judge the importance degree of each competitive evaluation index and the sorting of the competitiveness of listed companies.According to the listed company scores of factor for three years,the spatial correlation analysis of the three-year data was carried out by GeoDa and get the global Moran index and the local Moran index.And the GIS map can show the local Moran index and the competition center of gravity change within three years of change.According to the analysis results,most of China's highway industry listed companies at a low level of competitiveness,while only three listed companies above the average level;spatial correlation measure found that the highway competitiveness is in the trend of spatial decline.ESDA spatial exploratory analysis method has a high applicability to the competitiveness of highway companies,and it can analyze the spatial changes of competitiveness in combination with the general statistical methods.
