| Southwest China is rich in natural resources,including mountains,canyons,lakes,rivers,forests,grasslands and other natural landscapes,among which karst landforms,plateau landforms,canyon landforms and other unique landforms are the most famous.The southwest area has a beautiful ecological environment,rich animal and plant resources and unique ecological landscape.At the same time,the southwest is also a region inhabited by China’s ethnic minorities,with unique ethnic cultures and customs,including the Yi,Tibetan,Dai,Hani,Miao and other ethnic minorities.These ethnic cultures add a unique color to the tourism resources.At the same time,there are many kinds of tourism products in southwest China,such as Lijiang Old Town,Dali Old Town and Shilin in Yunnan Province.Guizhou Huangguoshu Waterfall,Zhenyuan Ancient City,etc.;Sichuan Jiuzhaigou,Mount Emei,Dujiangyan and so on,these tourism products have unique characteristics and attraction.At present,the epidemic has just ended,and the domestic tourism industry has shown a booming trend.However,in comparison,the four provinces and cities of Sichuan,Chongqing,Guizhou and Yunnan have an unbalanced development trend,and the economic development of tourism is not stable.Tourism income structure is an important index to measure the development and consumption of tourism economy in a country or region.Therefore,it is of great significance to analyze the development trend of domestic tourism income in southwest China,reveal its shortcomings and problems,and then adjust the structure of domestic tourism income,promote the development of tourism in Southwest China towards the direction of high quality and quantity,and improve the service level and quality of tourism.This paper firstly uses quantitative analysis methods such as dynamic change of domestic tourism components,income structure upgrading index and location entropy in the four provinces and cities in southwest China to compare and analyze the dynamic evolution and change rule of domestic tourism revenue structure in the four provinces and cities.In addition,this paper collected and sorted out relevant data of domestic tourism income in Southwest China from 2010 to 2019.Combined with ELES model,it further empirically analyzed the influence of prices of different consumption items on domestic tourism income in Southwest China from three aspects,namely marginal income tendency,income elasticity and price elasticity.Finally,this paper uses the panel fixed effect model and the data of domestic tourism revenue in Southwest China from 2005 to 2019 to make an empirical analysis of the influencing factors.The main research results of this paper are as follows:1.In 2019,transportation,catering,accommodation and shopping ranked first among provinces and cities in Southwest China;The four provinces and cities have great differences in catering and transportation,but small differences in the proportion of tourism.During the ten years from 2010 to 2019,the four provinces had very similar changes in the components of domestic tourism revenue;The maturity of domestic tourism income structure in Yunnan Province is the highest,followed by that in Sichuan Province.However,there is an obvious gap between Yunnan Province and regions with high quality tourism development level.The structure of domestic tourism income in these four provinces and cities in Southwest China is not up to the standard,and the proportion of non-basic tourism income in tourism economic income is insufficient.The traffic income belongs to the specialized income item in the domestic tourism income of Chongqing and Yunnan Province,but it lacks stability.Guizhou Province and Chongqing Municipality should strengthen the development and construction of scenic spots,Yunnan Province should increase the investment and construction of catering industry,and further explore the food culture and food culture tourism products of Yunnan Province.The relevant departments of Guizhou Province should further explore the shopping income demand of domestic tourism earners in Guizhou province;The non-basic consumption demand in Chongqing is insufficient,so the rationalization of Chongqing tourism income structure should be further adjusted.2.By analyzing the marginal propensity to consume of each income item,structurally,the lodging industry has the largest increase in income,followed by the shopping industry;From the level,if the domestic tourism income in Southwest China increases by 10 billion yuan,the basic income demand of domestic tourism in Southwest China will increase by 5.83 billion yuan,and the non-basic income demand will increase by 4.17 billion yuan.The analysis of demand income elasticity shows that the demand income elasticity of catering,accommodation,shopping and sightseeing are all greater than 1.Changes in domestic tourism income will certainly lead to changes in the demand for consumption items such as catering,accommodation,shopping and sightseeing.Keeping other conditions unchanged,the results of price elasticity of demand show that in southwest China,the price rise of various tourism income items will lead to the corresponding reduction of the demand,and the income demand of various items is more affected by their own prices,but less affected by the prices of other products.3.According to the previous analysis results,the influencing factors are selected and the regression analysis is carried out.The results show that the resident income price index,fixed assets in the accommodation industry and fixed assets in the catering industry have a negative effect on the tourism consumption of domestic tourists in southwest China,and have a inhibitory effect on the domestic tourism income.And the number of national nature reserves and highway mileage have promoting effect on domestic tourism income.In order to better stimulate the development potential of domestic tourism in southwest China,based on the above analysis results,this paper puts forward some suggestions such as strengthening the development and construction of non-basic tourism consumption projects,improving the domestic tourism consumption environment,raising the level of residents’ income and strengthening the development of nature reserves. |
