Correlation Analysis Of Tourism Industry In China Based On Complex Network

Nowadays,tourism has become one of the fastest growing economies in the word.Its size is expanding and its prospects are impressive.Tourism,as a kind of behavior,a kind of human life style,has entered the era of mass popularization.The tourist industry is not a common single industry,but an industry consisting of scattered by numerous“comprehensive industry”,which is composed of many economic sectors,restricted and affected by various economic sectors,and in turn to impact the other economic sectors.Therefore,the tourism industry is a highly correlated industry,its development through direct or indirect way to stimulate the development of various sectors of the national economy.Therefore,it is of great significance for the development of the economy and the optimization of the national economic structure to study the relevance of the tourism industry.In 2015,The National Bureau of statistics published the <2012 Chinese input-output table>.It was regard as the basic date source.Regarding the <China Statistical Yearbook(2013)> and <China Tourism Statistical Yearbook(2013)> as the complementary date.On the basis of the relevant activities of the tourism industry,select the corresponding industries from the 139 sectors,and from these industries by stripping extraction coefficient generalized tourism,with broad tourism industry as the research object of this dissertation.First of all,the dissertation studies the relationship between tourism itself and the other42 industrial sectors.And the spread effect in the national economy through the traditional input-output method.It is found that the structure of tourism consumption in our country has been optimized in recent years,and the proportion of non basic consumption structure in the whole tourism consumption structure has increased;The internal relationship of Chinese tourism industry is strong,and Chinese tourism industry has the obvious indirect relationship between the various industries of the national economy;The tourism industry plays a more and more important role in the national economy than the national economy.Secondly,to calculated,by input-output method,the direct consumption coefficient between the 140 sectors,with the industry as the node,the direct consumption coefficient for the right side,build an industrial association network.This dissertation makes a further study on the relationship between tourism industry and industry.It is proved that the network is a complex network and analyzes the characteristics of tourism in the network with the help of the static attribute analysis of the complex network.It found that the tourism industry has a large degree,point weight and large clustering coefficient in the industrial network.Thirdly,the dissertation makes use of the spectral bisection method in complex networks to divide into community structure,It is found that in the 140 sectors of the national economy,there is arelatively strong correlation between the 51 industrial sectors and the tourism industry,and the tourism industry has the strongest correlation with the 22 industrial sectors.Finally,this dissertation analyzes the importance of tourism industry in the industrial association network through the centrality of complex networks.According to the centrality of the three different algorithms from the network to determine the status of Chinese tourism industry in the national economic system is not the most important but it's position can not be ignored.This coincides with the conclusions drawn by the input-output method.
