Research On Key Industry Recognition And Matching Between Key Industry And Spatial Distribution In Hainan

Since the economic reform,Chinese economy has achieved a radical development and the level of industrialization and resident income have greatly improved.However,the economic growth rate has declined slightly in recent years after maintaining growth for more than 30 years at the rate of 8%.Some economists believe that China has fallen into'middle-income trap'.How to avoid it and create high income society has become the essential issue of economic increasing.According to the successful experience of advanced economies,the adjustment optimization and upgrading of industrial structure is the only way to overcome 'middle-income trap'.As the only province which is located in the tropics,Hainan not only has rich and unique natural resources,but also has a lot of preferential policy.But economic development level of Hainan has lagged far behind other special economic zones,and the total amount is even comparable to that of the backward regions in the west.The reasons for the economic development lagging are extremely complicated.Investment,consumption and exports have severely restricted the economic development of Hainan.The root of these problems lies in the low industrial structure level on the island which is hard to produce structural effects to improve economic development.Industrial restructuring and optimization in such a region with special geographical,historical,cultural and policy backgrounds can be completely borrowed without successful experience.We need to combine the various successful experiences from different advanced economies with the actual situation in Hainan to find out the most suitable model for Hainan.We think that it's quite crucial to recognize the key industries before exploring the industrial structure optimization and adjustment path.We should analysis the situation and problems of key industries which will be benefit to promote technological innovation,reduce production and operating costs,change the way of development.These meanings will improve the level of industries structure and achieve economy develop efficiently and sustainability in Hainan.We need to solve the following problems specifically.Whether the current industrial structure of Hainan is reasonable?How to choose region key industries scientifically?Which are the key industries in Hainan?Does the development of key industries match their spatial distribution?What is the path to optimize industrial structure through key industry upgrades?We conducted an in-depth analysis for these issues from chapter 3 to chapter 9.First of all,we analyzed the rationality of industrial structure in Hainan from the perspective of three industries' output structure,employment structure and comparative labor productivity and improved that its evolution process was different from traditional developed areas.The secondary industry was always the sector with the lowest proportion of output value.It had formed an industrial structure in which the tertiary industry is the largest and the first and second industries coexist.Then we measured industrial internal correlation,industrial extensibility,industrial stability,industrial centrality,industrial agglomeration and industrial circulation in the concept of industrial structure by the method of industry complex networks.We analyzed the influence of industrial structure to economic growth by the spatial econometrics model.The results showed that spatial factor had significant impact to economic growth.The centrality and circulation had little impact.The impact of agglomeration had the strongest effect while the inner-linkage had inhibiting effect to economic growth.So,improving economic outward,perfecting industrial chain,enhancing industrial stability and promoting industrial agglomeration were the most important structure effect indicators to choose key industries.Secondly,based on the input-output tables of China,Hainan and Taiwan in 2012,the industrial complex network models were given under the theory of complex network in chapter 4.We analyzed industrial structure of these regions from two dimensions:the whole indicators and individual indicators.The industrial structure of Hainan had high similarity with the whole country.Although the service industry and agriculture had stronger impetus to economic growth than the national average,their output value was in low level.Compared to Taiwan,which is a famous island tourist destination with complete industrial structure,the service industry still had large gaps.We proposed new mothed to choose key industries based on structure effect indicators and individual indicators then recognized the key imdustries of Hainan are agriculture,construction industry,tourist industry and financial industry.Thirdly,we analyzed the development,spatial distribution and industry-space matching of the four key industries one by one in Hainan from chapter 5 chapter 8 and verified its matching mechanism and economic growth effect.The agriculture was highly developed and its distribution had the feature of "north stronger than south","east stronger than west" and "periphery stronger than core".The development of agriculture is more dependent on the labor,capital,technology spillover effects and scale effects from industrial agglomeration than efficient and rational use of water and soil resources.The development trend of the construction industry has always been highly consistent with the real estate industry.Its spatial matching mechanism was the matching between city scale and industrial linkage.The city with lager population had stronger construction industry economic growth effect.An effective operating system has been initially formed between the various elements in tourist industry.The tourist industry in east was more developed than that in center and west.At present,the layout of tourism in Hainan had not yet reached the optimal state,and there was still room for adjustment in match quality.The scale of the modern financial services industry and its contribution to the service industry continued to expand.Hainan had gradually formed a relatively complete diversified financial organization system.Influenced by the degree of matching between factor supply structure and industrial linkage,the financial industry in Haikou and Sanya were more developed.The status quo of the island's financial industry gathering to the two places would continue in the future.Sanya would form second financial core city due to the stronger agglomeration effect.Finally,based on the above analysis,the overall policy recommendations for industrial structure optimization were proposed from the four perspectives of improving economic outward,perfecting industrial chain,enhancing industrial stability and promoting industrial agglomeration.Then we put forward policy recommendations for the development of key industries according to the characteristics of resources and environment in Hainan.We creatively proposed the strategy of "global education island" to promote tourism economic growth strategy and put forward construction path from the perspectives of government support,cooperation model and infrastructure construction.
