Research On The Regional Economic Growth Brought By The Belt And Road

China proposes one belt and one road initiative in new era when facing new world pattern.From the perspective of complex network,countries?regions? along "The Belt and Road" are seen as a whole economic system,and international trade is a comprehensive result carried out by different countries?regions?.Using "The Belt and Road along the 65 nation international trade history data from 2006 to 2016,this article build a regional trade weighted network about countries?regions? along" The Belt and Road ".At the same time,based on complex network,this paper also uses the specific index to reflect the features about the trade weighted network.Finally,based on the new classical economic growth theory,a model is also built to reflect the influence on the regional economic growth,and the index is seen as trade network variables.besides,based on the theory of new economic geography,by introducing spatial factors,the traditional econometric model is extended to spatial econometric models.we can get following conclusion:Firstly,the trade of countries?regions? along "The Belt and Road" have an increase trend,but after 2014,it start to decrease.At the same time,the vertex intensity of the trade network plays a positive role in the economic development of the whole region.The output of the whole area will increase by 0.342% when the vertex intensity increases by 1%.This reflects the importance of international trade to the regional economy.Under the severe condition in 2014,only do countries?regions? work together and actively promote mutual trade,they can promote economic development.Secondly,the weight of entropy and entropy intensity network are showing a decrease of entropy trend.That means the node strength distribution and trade flow distribution appears more and more uneven trend between the countries?regions? along The Belt and Road,so the " the rich richer and the poor poorer " phenomenon exists nowadays.Finally,the average agglomeration coefficient of the network is on the rise,and the willingness of countries?regions? to establish trade relations with other countries?regions? has been strengthened.And actively participating in the establishment of trade relations in other countries?regions? has a positive role in promoting the regional economy.The regression results from the 5.5 show that when the aggregation coefficient of the vertex increases by 1%,the output in the whole region increases by 0.113%,which means the development of network trade has a significant role in promoting the regional economy.Therefore,in the process of implementation of the "The Belt and Road" policy,trade flow is the key point to implement and promote,and strengthening the whole area of trade is a good way to promote economic development.
