The Study On The Coordinating Development Of Hydropower Exploitation And Regional Economy

Hydropower projects have strong regional functions and regional economic characteristics. This lies in the fact that apart from the function of generating electricity, hydropower projects have the social effects such as flood prevention, irrigation, water supply, environmental protection and communication. Threfore, when exploiting hydropower projects, we have to not only evaluate its function and economic benefit, but also keep an eye on their social value, and make a comprehensive evaluation by integrating the regional economic development. In addition, we need to pay attention to their promotion on the development of regional economy.There are many industries related to hydropower exploitation. Hydropower exploitation oriented in "polar nucleus" can form an industry conglomeration of promoting regional coordinating development, helps to bring along the development of regional economy, improves the infrastructure, and pushes forward the development of regional economy. As a combination of primary and secondary energy, hydropower can form a system of its own, with cheap and stable cost which can enhance the competitiveness of regional economy.Hydropower exploitation characterizes in capital intensiveness and long construction cycle. Slow and small-scale development of hydropower will lead to waste of resources. However, fast and large-scale development will make the supply of electricity surplus and the development of regional economy unbalanced.The article makes a quantitative analysis on the correlation of economic development of large-scale hydropower projects in the southwest area as Yunnan, Guizhou, and Sichuan provinces in 1990s, to show that hydropower project can bring about comprehensive benefits and push forward the development of regional economy, apart from its contribution of generating electric power.The study does not mainly focus on the relationship between the development of a specific hydropower project and regional economy, but on the relationship of the overall development of the hydropowers in various provinces and the regional economy. With demonstration and criterion analysis, we find out the decisive factors and the relationship between hydropower exploitation and coordinating development of regional economy from the theoretical level, and reveal the inner relationship between hydropower exploitation, the development of regional economy and the correlative rules. By integrating theoretical analysis with demonstration analysis supplemented with index evaluation system, macro-model and quantitative calculation, the article explores the correlation between hydropower exploitation, the development of regional economy and their social impacts. It also makes comprehensive and systematic study on the economic and social functions of hydropower projects.In regard to the relationship between hydropower exploitation and the regional economy, most previous studies focus on the economic and social value of a specific hydropower project. This article takes an explicit view that large-scale hydropower projects play a vital role in the development of regional economy, hydropower exploitation should be in coordination with the development of regional economy which should be taken as a whole, and that it is advantageous to the development of regional economy to congregate industries related to hydropower exploitation in the hydropower resources region.From the analysis, it is easy to find that in respect to the construction of hydro resources, the non-electricity fuction is greater than electric function and that the comprehensive value is greater than that of electricity.This article proposes the theory of polar nucleus of hydropower exploitation. There are many industries related to hydropower exploitation, the sustainable development of the industries help to accumulate the intrinsic power and push the regional development, thus promoting the development of regional economy. Various stages of hydropower exploitation can form the domino effect in congregating the industries related to hydropower and bring about the coordinating development in this area.The idea on hydropower exploitation must be at the right moment and moderate. The establishment of macroscopic model of the coordinating development between hydropower exploitation and regional economy demonstrates that we need to pay attention to both the development speed and the coordination of development, and that excessive speed or slow speed development goes against the coordinating development of economy.This article has established an appraisal model on the social value and comprehensive function of the hydro power station and tech-economical method of overall plan on development of water resources. At present most of the studies are mainly concerned with the case study on the economic benefit of a specific hydropower project, on the optimization of the design of a power station to reduce the cost, on the reasonable electric price from the electricity system, or on the contribution of a specific hydropower to the development of regional economy. This article proposes that we analyze the quantitative relations of the influence of the investment of hydropower in an area on regional economy, and takes not only electricity but also other functions into consideration, which is of more universal and guiding functions.
