Research On China's Inter Provincial Energy Efficiency From The Perspective Of Market Segmentation

The economy of China has made an unprecedented achievement during the 40 th anniversary of reform and opening-up.From 1990 to 2014,the economy in China maintained a rapid growth tendency.moreover,for several years,it supported growth with a double-digit;At the same period,there was a prominent problem on restricting the sustainable development of the economy because of China's high energy consumption which results environmental pollution and ecological damaged.China has been the world's second-largest oil consumer and third-largest oil importer since 2004,although it was an oil exported country completely at 10 years ago;In 2017,China has become the largest oil importer around the whole world,exceeded the United States.With the increasingly dependence of oil on the overseas,there was a great risk on sustainable development and security of energy.We have to realize that the short of energy and inefficiency resulted in serious problems in development,instead of abundant energy and low ratio of possession.In 2013,seven of the world's 10 most acute polluted cities were in China,according to the report “national environmental analysis of the People's Republic of China toward an environmentally sustainable future”released by the Asian development bank and Tsinghua university,which was the environmental cost of China's rapid growth driven by consuming energy.Since the 12 th Five-years plan,especially the 18 th CPC national congress,China has attached great importance to keep the balance between the speed of economic development and the effort of energy conservation and emission reduction.On November 30th2015,President Xi Jinping attended the opening ceremony of the Paris conference on climate change management,delivering a speech titled "Work together to build a win-win cooperation,fair and reasonable climate change governance mechanism".On behalf of the Chinese government promised that we will meet the requirement on peak Carbon dioxide emissions and strive to achieve it as soon as possible around 2030,Carbon dioxide emissions ratio unit of GDP will be reduced by 60-65% compared with 2005,and non-fossil energy at the proportion of primary energy consumption will account for about 20%.The concept of green development was also incorporated into one of the five development concepts of the 13 th five-year plan during the fifth plenary session of the 18 th CPC Central Committee.They emphasize reasonably control of energy consumption at the 13 th five-year energy plan,the total amount of primary energy consumption should be accounted for 4.5 billion tons of standard coal,and the total amount of coal consumption will be about 3.8 billion tons of standard coal by 2020.Meanwhile,the total energy consumption of 10,000 yuan of gross domestic product will be reduced by 15% compared with 2015;Caifang,vice-president of the Chinese Academy of Social Sciences,stated China's economic growth should maintain an interval between 6.2 per cent and 6.7 per cent during the 13 th five-year plan period.With the triple goals of sustainable economic growth,energy truth conservation and environmental protection,only realize these three goals can we improve energy efficiency.There are lots of literatures on how to improve energy efficiency and influence factors of energy efficiency.Some of them study from the aspects of industrial structure,level of foreign investment,international trade and level of urbanization.This survey,based on the previous literatures,provide a new point for energy efficiency improvement.There are three part in this survey from the perspective of market segmentation.Firstly,I sorts out the reasons and the calculation methods of China's market segmentation,using the price index method to measure the degree of market segmentation in each provinces,and make a detailed analysis of the measurement results;Secondly,on the basis of a comprehensive understanding of China's energy efficiency status,I analyze the mechanism of market segmentation affecting energy efficiency theoretically and three theoretical assumptions are proposed which are: market segmentation impacts the energy efficiency mechanism through technological progress,efficiency of scale and allocation;the panel data model is used to conduct quantitative empirical analysis on the theoretical hypothesis that market segmentation affects energy efficiency mechanism;the degree of market segmentation will reduce the scale efficiency,technological advance and the promotion of allocation efficiency on energy efficiency,moreover it will limit the improvement of energy efficiency.Lastly,there will be proposed suggestions according to the analysis of empirical results.
