Research On The Spatial Spillover Effect Of Tourism Economy-taking Guangxi As An Example

The development of tourism economy has become a new growth point of guangxi’s national economy and society,a series of contradictions and problems have arisen.Many cities focus too much on the development of local tourism industry while ignoring the overall grasp of guangxi’s tourism development,resulting in repeated infrastructure construction,unbalanced tourism economic development between cities,mismatch between market supply and market demand,insufficient structural benefits of tourism development and other problems.Therefore,it is necessary to measure the spillover effect of tourism economy and put forward corresponding policy suggestions for the optimization of the spatial distribution of tourism industry in Guangxi.The basic test of agglomeration of tourism growth is analyzed by using global spatial autocorrelation and local spatial autocorrelation.Then,the impacts of different variables on tourism growth as well as spatial spillover effect and its accurate measurement are discussed.The routes of spillover between cities were revealed by clustering analysis method,vector autoregressive model and impulse response function,and the transmission network of tourism economic spillover in Guangxi Zhuang Autonomous Region was constructed.Finally,according to the research results,the corresponding policy basis and research prospects are put forward.The main conclusions of this study are as follows:Firstly,tourism growth in Guangxi Zhuang Autonomous Region has significant spatial heterogeneity and spatial correlation.From the perspective of the spatial pattern of tourism economic development in Guangxi Zhuang Autonomous Region,both the per capita tourism income and the proportion of total tourism income to GDP are higher in northern cities and southern coastal cities,and lower in eastern cities and western cities.The spatial correlation analysis of tourism growth shows that the tourism growth of all cities in Guangxi presents a significant positive correlation,and the correlation gradually increases with time.The local autocorrelation also indicates that the degree of tourism growth is increasing,and the imbalance of regional tourism economy will further intensify.Secondly,by analyzing the tourism data of Guangxi from 2010 to2019,it can be seen that there is a significant spatial spillover phenomenon in the tourism growth of Guangxi.On average,every 1%growth of local tourism economy will promote 0.3618745% growth of tourism economy in surrounding cities,bringing obvious spatial spillover and negative spatial spillover effect.Most of the variables play a significant role in promoting the growth of tourism economy,among which the urbanization level and economic development level have the greatest impact on the development of tourism economy,promoting the rapid growth of tourism economy.However,regional openness and year-end savings balance of urban and rural residents restrain the growth of tourism economy to a certain extent.The above results show that the development of tourism economy in neighboring cities is not only competitive on the whole,but also has a certain benign interaction,forming scale effect.The increasingly close connection between different cities has a significant spatial spillover effect on tourism economy.In the analysis of spatio-temporal evolution of spillover effects,it is found that the overall positive spillover effects show a declining trend through the spatial spillover studies from 2010 to 2014 and from 2015 to2019.When it comes to specific variables,regional openness is always an important factor inhibiting tourism growth,and the inhibiting effect is increasing.The tourism economic growth effect brought by the urbanization level in the latter stage is significantly greater than that in the former stage.Thirdly,through the tourism spillover transmission network,the spillover effect of tourism economic growth in core cities is analyzed.It is found that there are certain economic interaction relations in cluster areas,mainly in the weak competitiveness cluster areas,which are mainly one-way interaction relations,and two-way interaction relations only exist between Wuzhou and Hezhou.Guilin has a strong positive spatial spillover effect,which can significantly promote the growth of tourism economy in surrounding cities.Nanning also has a certain spillover effect on the surrounding cities,which is also promoted by the tourism growth of Baise.The spatial spillover effect of Beihai city is not significant,while wuzhou city has a strong interaction with the tourism economy of surrounding cities.Major policy recommendations: Firstly,build tourism industry with regional characteristics on the basis of tourism resource endowment;Secondly,coordinate the spatial distribution of tourism industry and strengthen regional tourism cooperation;Thirdly,promote urbanization and economic development and construction,and tap new driving force of tourism economic growth;Fourth,carry out reasonable industrial coordination to promote high-quality transformation of tourism economy development.
