The Spatio-Temporal Evolvement Of Spatial Interaction Among Cities Of The Provincial Border Region

Space interaction is one of the most important topics in economic geography,and it is a promising field.For a long time,in the economic system of provincial,peripheral provinces border region,promote the coordinated development of provinces border region is the difficulty in the development of area as a whole.Therefore,the provincial border area is a very problem areas of research significance,the provincial boundary region related theoretical and empirical study,promoting the coordinated development,this is an area of special type of is a new proposition in the research of regional harmonious development in our country.Based on the shear effect as the breakthrough point,based on the gravity model and potential of the improved model,the analysis from two dimensions of prefecture and county Jin Shan Yu Yellow River Golden DeHa Regions for nearly 15 years of spatial interaction between city and city of potential,reveals the general rule of provincial border regions space interaction and the formation mechanism,and explore the Jin Shan Yu Yellow River Golden DeHa Regions of interaction between urban space and urban potential strength of main influence factors by analysis:(1)The urban comprehensive strength in the study area is weak and the quality of the city is low.(2)Interregional spatial elements flow pattern is the interactive type and weaker.(3)Research area from the prefecture level cities in the urban space contact strength scale,Jin Shan Yu Yellow River Golden DeHa Regions from city to city space connection with general contact is given priority to,the space between the city don't close,interaction strength is generally low,and the spatial relationship between city have been gradually ascending trend in the study area not highlight the center of the city.(4)Urban space contact from county scales,municipal districts and counties,spatial interaction between intensity is bigger compared with the values of various interaction within the sameadministrative region,smaller values of the function between counties and cities across the administrative areas.(5)Urban potential is generally weak,radiation ability is low dominant area not at the heart of the city.(6)Potential of urban space distribution imbalance,urban spatial distribution of potential is scattered,and the radiation range is small,the effect is not obvious,gathering ability is weak spatial variation of various potential difference to be markedly in the study area,present some regularity,the capability of space radiation of southwest from central to regional southeast,southwest area city potential strong and rapid change,expanding external radiation ability,wide radiation range,strong ability to gather,and shrinking area counties and cities in central China radiation ability,radiation capacity showed a trend of gradually fade,northern region is a potential weak areas of space radiation.On this basis,from the urban comprehensive strength industrial complementarity traffic administrative border effect factors as well as the historical and cultural factors of Jin Shan Yu Yellow River Golden DeHa Regions several aspects analyzes the influence factors of spatial interaction between cities and enrich the relevant theories of provinces border regional harmonious development,which will provide a scientific basis for the regional cooperation policy in the study area,more for the country to accelerate the process of regional integration has important reference meaning.
