Abstract:

Traffic convenience and informatization have an important impact on the gathering of high-end service industries. Traffic convenience changes the spatial layout of elements aggregation physically, and informatization changes the layout and connection of elements in an intangible and tangible way. Therefore, are the two factors of transportation efficiency and informatization level that are extremely important to the flow of factors affect the gathering of the high-end service industry? What is the mechanism of action between them? Is there a difference in the impact of traffic convenience and informatization level on the gathering of high-end services in the different gathering levels of the high-end service industry? These problems have certain research significance. This paper theoretically analyzes the positive mechanism，negative mechanism and the interaction mechanism of traffic convenience and informatization level on the gathering of the high-end service industry. This paper also conducted an empirical analysis. Based on the panel data of 28 provinces and cities in China from 2005 to 2014.This paper empirically studies the mechanism of transportation convenience,informatization level and interaction on the gathering of the high-end service industry by using panel data model and quantile regression model. The result shows that the general elasticity is negative for traffic convenience to the gathering high-end service industry; Under the low and middle level of high-end service industry gathering, traffic convenience has no significant effect on the gathering of high-end service industry; Under the high level of high-end service industry gathering, traffic convenience has a positive effect on the gathering of high-end service industry which positive effect is still increasing. The general elasticity of informatization level to high-end service industry gathering is positive; under the low and middle level of high-end service industry, the positive effect of informatization level on the gathering of high-end service industry increases progressively; under the high level of high-end service industry gathering, the positive effect of information technology on the gathering of high-end service industry weakens and unapparent. The general elasticity of interaction to high-end service industry gathering is positive; under the low and middle level of high-end service industry gathering, the positive effect of interaction on high-end service industry gathering increases progressively; under the high level of high-end service industry gathering, the positive effect of interaction on high-end service industry gathering is lower progressively. Therefore, this paper proposes to improve the transportation convenience between urban areas by increasing the construction of transportation infrastructure, strengthen the construction of high-end service industry clusters in underdeveloped areas and pay more attention to the coordinated development of traffic convenience and informatization level in underdeveloped areas. The strengthening and improvement of the above three aspects may promote the development of China′s high-end service industry.
