Interactions Between The Various Regions Of Beijing, Tianjin And Hebei Based On DAG

The regional development issues of Beijing,Tianjin and Hebei have been raised formany years, but due to various factors, the regional coordination has been lower than theYangtze River Delta, The coordination of Yangtze River Delta regional is at a high degreeof integration, Beijing and Tianjin region should learn from Yangtze River Delta. Thisarticle will use directed acyclic graph (DAG) technology to causal relationship betweenthe economy over the same period of quantitative analysis among Beijing, Tianjin andHebei, and the Yangtze River Delta regions with the interaction between the relationshipfor comparative analysis.Accordingly, the corresponding measures to improve theintegration of Beijing,Tianjin and Hebei.First, the paper describes the relevant economic theory of regional relations and directedacyclic graph method, and then analysis the problems in the development zone of Beijing,Tianjin and Hebei.Compared with the Yangtze River Delta, the overall economic strengthof Beijing Tianjin and Hebei is weak, internal development is imbalance, and thedevelopment of Beijing,Tianjin and Hebei is relatively independent. The future researchwill be based on the theoretical and empirical basis for analysis.Secondly, through the vector autoregressive (VAR) model, obtained the disturbancecorrelation matrix, prepare for the future analysis of DAG.Again, based on the correlation between variables of the disturbance coefficient matrix,use directed acyclic graph method, obtained the same period causal relationship among thevarious regions of Beijing, Tianjin and Hebei.Then, based on the DAG results, variancedecomposition reflects the dynamic interaction relationship between Beijing, Tianjin andHebei. And comparative analysis of the Yangtze River Delta, it can be seen more clearly ofthe shortcomings of economic relations between the coordinated development of thecenter city of Beijing, Tianjin and surroundings, learn experience from Yangtze RiverDelta, and then proposed to promote the integration measures between Beijing,Tianjin andHebei.The DAG results show that Beijing as the first city, its radiation has not been fullyexploited, and Beijing,Tianjin region highlighted the phenomenon of independent development, regional integration of Beijing, Tianjin and Hebei is lower than the level ofYangtze River Delta region. At the same time, based on DAG,the variance decompositionanalysis showed that the radiation of Beijing and Tianjin for Hebei is much smaller thanthe impact of Beijing and Tianjin from Hebei.Finally, all of above analysis, propose the corresponding proposals.Joint developmentof Beijing and Tianjin, Beijing and Tianjin dislocation development, Hebei Perspectivethinking of integration countermeasures.
