Research On The Impact Of Smart Grid Construction To National Economy

By consulting the relevant literature and applying the input-output analysis,this paper has studied the relationship between China's power industry and national economy,and then used the input and output prediction mathods to get the China's input-output tables in 2020. On this basis, Compared and analyzed the relationship between China's power industry and national economy Before and after the construction of smart grid. Finally got the influence of smart grid construction to the national economy.Through the analysis, this paper got the following conclusions:(1) comparing the Previous input-output tables and forecast input-output table in 2020,this paper found that by the constructing of smart grid the power industry's position in the national economy is rising and changing, the power industry's has gradually changed from the traditional basic industries into an important entity industry of national economy, The leading role in promoting the national economy has been significantly enhanced and was gradually becoming the backbone of the rapid development of national economy.(2) The direct consumption coefficient and the total input coefficients of national economic sectors to the electricity industry are in a high level, are higher. there are strong dependencies Between the various industries and the electricity industry. Especially with the extractive industries, machinery and equipment manufacturing, metal manufacturing, chemical and other industries rely on the highest level.(3) Power industry is an important basic industry in China, has played a very important role in the national economy. The development of power industry has a strong sense ability to the national economy, so the power industry needs to accelerate the development,especialy should strengthen the smart grid construction.(4) China's power industry can be developed into a leading industry. According to input-output theory, if the influence of an industry coefficients and sensitivity coefficients are greater, it can be used as leading industries. Whether in terms of influence or in terms of sensitivity of the power industry, it means that power industry have a strong impact on the national economy, the power industry should therefore be classified as national leading industries.
