Research On Influencing Factors Of Energy Efficiency And Promoting Countermeasures In Dalian

Energy problem is one of the greatest challenges of Chinese economic development.Energy development is faced with dual pressure that meets the demand of economic and social development and reduces environmental pollution.Energy efficiency will alleviate these problems, bring economic benefit and enhance overall competitiveness.Therefore,energy efficiency has become an effective way and an important guarantee for sustainable development all over the world.Entering the 21st century,as an old heavy-industry city,Dalian has undergone rapid economic development.It is clear that energy problem constraints the economic development of Dalian.Based on the background combined with the economic development of Dalian and the actual situation of energy consumption,We systematically recall the study of concept,measuring indicators as well as appraising methods and influencing factors of energy efficiency at home and abroad.Then,we collect the data of influencing factors of energy efficiency of Dalian and extract the main factors using the method of stepwise regression analysis.The results indicate that R&D input accounted for the proportion of GDP,industrial structure and informatization are the three main influencing factors of energy efficiency of Dalian.Subsequently,we make a model of influencing factors of energy efficiency by virtue of Ewiews.According to the model,we make a comparative analysis between Dalian and Shanghai.The results show that R&D input accounted for a lower proportion of GDP,less adjustment of industrial structure and lower level of energy informatization constraint promotion of energy efficiency of Dalian.Based on regression model, we forecast the energy consumption per 10000 yuan GDP of Dalian in 2010-2020 using the method of scenario analysis and make scientific analyses of predicted results.Finally,according to the key constraint factors as well as the predicted results,we make a proposal of raising R&D input accounted for the proportion of GDP,promoting the optimization and upgrading of industrial structure,perfecting informatization of energy industry in order to reduce energy consumption of Dalian and increase energy efficiency which provide a scientific basis for the concerns of saving energy and reducing consumption,enhancing the capacity of scientific and technological innovation as well as taking the road of new industrialization.
