| Since the late 1980’s,after nearly 30 years of rapid development,China’s highway mileage jumped from zero to 12.35 Thousands of kilometers at the end of 2015.It is longest than any other country.The large and convenient highway network not only meets the needs of social and economic development of transportation,but also plays an important role in promoting economic development and improve people’s quality of life.But because of the need to consume large amounts of resources in the highway construction,so as the important content of highway planning,the research on reasonable scale along with the development of the highway.Especially in the present stage,China is implementing supply-side structural reform,so it is great significant for the sustainable development of social economy to continue study the highway reasonable scale.In the study of highway reasonable scale,factors affecting research is one of the main content.Reasonable and sufficient to determine the factors which influence,not only can improve the scientific and reasonable scale research integrity,at the same time also can improve the uniformity of research conclusion.In this paper,the influencing factors of the reasonable scale of Highway is the object,based on the transportation and related economic theory,firstly the author analysis the economic attribute of the highway and the relationship between the social economic and highway.Then the exploratory factor analysis method was used to study the common features between various influencing factors,and on this basis,combined with the theory and practice experience built the index system of all kinds of influencing factors.Finally I use the structural equation model to deeply study the influence degree and the path,found that social economic development level and the transportation demand level has significant positive influence to the reasonable scale of highway,and social economy is the primary factors affecting highway reasonable scale,followed by traffic demand factors. |
