Some research institutions internationally determine the status of economic growth through the analysis of actual consumption. The power industry has an important impact on the development of basic industries of the national economy, the development of other sectors of various industries play an essential supporting role. Production of electricity supply for economic development improves people＇ s livelihood and social progress, it provides a necessary condition, and power shortages, in turn it seriously affects the country＇ s economic development and living. Therefore, the power and economic growth （GDP） is to study the relationship, it will be under conditions of scarce resources saving energy, electric power development plan to develop the scientific and industrial policy system, and promote the healthy and rapid economic growth.展开更多
