| Because of the particularity of industry status, tourism industry is well-known as the "sunrise industry", "low-carbon and environmental-protection industry" and "leading industry". With the development of society and economy, the world-wild tourism has already become an indispensable important component in the process of modern economic and social development. In recent years, the rapid development of tourism industry around the world has driven the rapid development of related industries in the surrounding area, the high correlation of the tourism industry can not only optimize the structure of regional economy, but also can effectively promote the process of urbanization area, further more, it can effectively alleviate the situation in areas with high employment pressure. Many potential advantages of tourism industry have been proved in practice and gradually accepted by the other countries and regions in the world. Since China formally identified the policies of reform and opening-up in 1978, vigorously develop the national tourism has become an important way to promote regional economic development in China. During the period of October 1978 to July 1979, comrade Deng xiaoping had five times speech, he stressed that the potential development space of tourism industry is huge, we must develop tourism as soon as possible. Tourism industry has played a positive role in various aspects and quickly became the pillar industry of economic development and social progress of a country or a region. Development of the tourism industry, not only can it practice the party’s concept of scientific development to the actual situation(that is the "the harmonious development of man and nature"), also it can realize win-win situation of economic development and social progress. At present, the development of tourism industry is in a critical period of transformation and upgrading in China, as the tourism development planning in various provinces and cities or regions of the country’s is picking up, the tourism’s industry status has been improved rapidly in different provinces or regions of its social and economic. In order to achieve a better development of tourism, China has formulated and implemented the tourism industry “fifteen” plan and “Vision 2015 development plan”. With the development of provinces and cities or regional tourism is carrying on like a raging fire, there are some provinces and areas have put the development of tourism as a key industries and pillar industries". Under the influence of this kind of situation, the Guangxi zhuang autonomous region tourism industry attached great importance and vigorously promotion from the relevant departments, and eventually won the leap type development. As a big provinces of ethnic tourism, the rapid development of Guangxi’s tourist industry has maken an important contribution to the growth of China’s GDP, but in the rapidly developing process of Guangxi’s tourism industry, there also is a problem that is low efficiency of input and output of tourism, which can cause great harm to the sustainable development of tourism industry of Guangxi zhuang autonomous region.As a new research field in Date Envelopment Analysis, it’s a good method which can objectively evaluate the relative effectiveness of decision-making units with more multiple similar input and output indicators(DUM). Due to the input index of the tourism industry involves multiple factors, using the DEA model to analysis the efficiency of tourism’s input and output of Guangxi, it will have a great significance in promoting the sustainable development of Guangxi’s tourism industry, narrowing the gap between rich and poor regions significantly, balancing the level of development between urban and rural, constructing a harmonious and beautiful China.First of all, consulting a large number of literature which related tourism’s input and output efficiency in national regions at home and abroad, then combed the related research results carefully and to find out the writing starting point and the breakthrough point of this article, namely the innovation of this article. Second, laying a solid theoretical foundation from the angle of Economics of tourism, regional economics and development economics for that we can study the problem of Guangxi zhuang autonomous region’ s tourism input and output in different years and the deep reason for analysis of the fore problems in this paper. Then, using the DEA model of Guangxi zhuang autonomous region tourism input and output efficiency of the empirical analysis, from the different factors of five tourism inputs to explain the reasons for low efficiency of Guangxi’ s tourism input and output of in different years. Finally, combining with the actual situation of the tourism development in Guangxi zhuang autonomous region, we put forward seven pieces of measures for improving the input and output efficiency of Guangxi’s tourism according to the above section of reason analysis. |
