Construction of regional integrated transportation networks in Qinghai province under circular economy model

Circular economy is a new concept of development and an economic growth model. This paper studied the relationship between the integrated transport network and circular economy; the characteristics of traffic flow developed by circular economy in Qinghai province, and constructed the regional integrated network mating with circular economy in Qinghai province. Results showed that passenger and cargo transportation capacity has obvious positive correlation with economy development, but the growth rate of passenger and cargo transportation does not match smoothly with that of Qinghai provincial GDP growth in some periods, their significant differences imply that the increase of passenger and cargo transportation is strongly affected by other factors. Traffic flow has positive correlation with road network levels. The development of Qinghai province circular economy mainly relies on the Qaidam areas and the east circular economy area as the core of Xining now. On the above basis, also put forward the suggestions of construction regional integrated network mating with circular economy in Qinghai province to the development of the regional circular economy in the future. © 2011 IEEE.
