Empirical Analysis and Research on Urban Energy Efficiency Measurement Based on Computer Technology and Total Factor Framework

The utilization rate of energy can reflect the economic development quality and technical level of a country and a region, which directly affects the sustainable economic development. With the rapid progress of China's urbanization, the total energy consumption is constantly rising, among which the urban energy consumption accounts for more than two thirds of the total energy consumption. Therefore, the urban energy utilization efficiency largely determines the overall level of China's energy utilization. The results show that the growth rate of energy efficiency and the growth rate of energy use technology efficiency decrease under the constraint of environment. At the same time, due to the neglect of energy emission reduction technologies, the growth rate of technological progress in energy use decreases. As is known to all, carbon dioxide emitted by energy consumption causes a surge in greenhouse gases, leading to global climate anomalies, and China's carbon dioxide emissions have now surpassed the United States as the number one carbon dioxide emitter. Energy efficiency is an important "energy source". Drew Warren (1982) regards energy efficiency as the "fifth energy source" alongside coal, oil, natural gas and electricity. Energy efficiency needs to play a major role as a "source of energy" as it can reduce reliance on energy. Based on the analysis of the urban energy research framework, the article of urban energy efficiency measures are divided into broad sense and narrow sense two aspects, combined with domestic and foreign research results, respectively, the energy efficiency at home and abroad to use comparative evaluation index, energy consumption data acquisition method, from two aspects of theory and practical application discusses the applicable scope of different measure methods and its advantages and limitations in the urban energy efficiency analysis, and points out how to enhance the applicability of the overseas related research methods and clear policy boundary scope of relevant research conclusion.
