The Measurement Of Chinese Infrastructures’ Spatial Spillover Effects In Transportation And Telecommunication Areas

Three decades of reform and opening up, China has made remarkable achievements. GDP growth rate is kept at 9.7%, which is much higher than the 3.27% compared to the number achieved by the whole world during the same period, behind the sustained and rapid economic growth there comes an indispensable objective fact that the rapid development of China’s infrastructures are matters. In the long run, transport, telecommunications-as the the representitives of infrastructures-are social advance factors and solid foundations, and considered the necessary elements in fulfilling economic growth and social development.In recent years, the construction of transportation is no longer entirely confined to the transportation network nationwide coverage, transportation efficiency is now thought to be responsible for the limitation in constructing transportation, which means it pays more attention to the quality changes rather than the quantity changes, in the meanwhile, the development level in different areas in China should also be considered. Specifically speaking, the annual growth rate in high-speed railway mileage shows as high as 75%, and the number of highways in the period of 2010-2013 has also broke above 10, reaching to 12.1%. The intensity of the transport network also showed a decreasing trend from southeast to northwest. Similarly, the development in fixed, mobile and the promotion of broadband networks in the telecommunications infrastructure has been gradually turning to the Internet technically innovative stage, the public are showing higher requirements to the mobile communication devices including mobile phone, and these requirements are also pushing the 3G,4G network out.With the improvements in traffic and telecommunication infrastructure, its network and external properties lead to a inter action between areas and that phenomena has been caught by domestic and foreign scholars, and in recent years. In the meantime, the rapid development of regional economics, geography economics provides a good theoretical basis for the research in studying in the spillover effects. More and more studies have found that the infrastructure for economic growth do exist obvious spatial spillover effects, but this effect depends on the methods and variables taken in the research, of which the transportation infrastructure has more documents and relatively few studies on telecommunications infrastructure.Therefore, based on the above considerations, this article will take the transportation and telecommunication infrastructures as the objects to examine the spillovers effects of basic infrastructures on the economic growth by using 26 provinces and autonomous regions data start form 2003 to 2012 as the panel data. This paper tried to make a measurement of the spatial correlation in basic infrastructures by using the geographical proximity and economic distance between two spatial weights matrix., and decompose the economic effects by applying the Dubbin model, the outcomes is divided into a direct effects within the provinces and the spillover effects--called indirect effects as well, happened between two more provinces. The results come as follows:(1) No matter taking any one as the spatial weights matrix, the improvement of transportation infrastructure has a positive influence in provincial economy in the fixed and random effects in spatial SDM model, but it behaves negative to the neighboring provinces, that is to say, transportation infrastructures has positive and direct effects and negative spillover effects. And it partly true in communication infrastructures for being also positive in provincial economy, but when it comes to the neighboring provinces, its effects varies in different modes, in the fixed effect mode, the spillover effects behave negative while in random mode it points to a positive side.(2) From the perspective of total effect, the total effect that transportation infrastructure has to the economy growth shows negative in the fixed effect mode, which means that the improvement in transportation infrastructure area will Inhibit economic growth as a whole. In random mode, telecommunication infrastructure has a significant role in achieving economic growth, and this conclusion works in the whole nation.(3) The empirical results is significant and it is the background of the conclusion that the improvement in traffic and telecommunication infrastructures has more indirect impacts to neighbor provinces than the direct impacts to local province.(4) whether the transportation or telecommunications infrastructure, both has slight feedback effects on the economy.Based on the above analysis and the current situation of the development of infrastructure, this essay dedicated to supplying an theoretical basis of specification and policy suggestions for the government and related sectors in order to make an endeavor in making development plan.
