Study On Energy Constraint During District Development

Energy is not only important factor of production for development of district but also indispensable means of subsistence for the people lived in the district. Energy system has great influence in a district. Energy constraint that a district suffered during its development would sway many fields of the district, such as economy, society, environment, and so on. So, research work of energy constraint is very complicated, and academic research do not get unified opinions on this issue. In response to this phenomenon, this paper, from the following aspects, makes its own efforts:This paper puts forward a new opinion that research work of energy has diffient levels. Research on energy issues from the bottom in turn can be divided into four levels, namely "basic layer", "cognition layer", "analysis layer", and "solution layer". Enery layer is the basic for research work in upper layer. According this opinion, to analyze the existing research articles on energy research can discover the reason led energy research work to chaos. The reason is that most research work only paid attention on questions in "analysis layer" and "solution layer", few research works analyzed questions in "basic layer" and "cognition layer", such as"does energy constraint exist?","how to classify energy constraint?","how to measure energy constraint?", and so on.Learn from Maslow's Hierarchy of Needs theory, this paper divides energy demand of a district into four hierarchies, From lower to higher, named"basic living demand","society safe demand","production demand", and"entertainment demand". Although there are many Individuals in most districts, part of higher energy demand perhaps be satisfied before part of lower energy demand, but totally, energy demand of whole district will be satisfied according to the order from low to high. Futhermore, this paper proves that energy constraint could be exist during development of any district.Taking the difference of the extent and reason of energy constraint among different districts, this paper gives a method to classified energy constraint, and put forward the concept, namely"degree of energy constraint", and its calculation method. On the basis of calculating opening degree and development degree of one district, through calculating the difference of quantity, time, category, and space between energy demand and supply in the district, degree of energy constraint of the district can be measured, which provied a method quantitative research on energy constraint.After classifying and quantitative measuring energy constraint, this paper does some research work on anlyzing the relationship among energy, economy, environment, people, society, industrial structure, and so on, and does the empirical study on China. The results show that industrial stucture, age and space distribution of people, GDP,etc are important factors could sway energy demand of one district. Accoding to the method put forward by this paper, degree of energy constraint of most provinces in China is measured, and the corresponding measures to resolve their energy constraint are advised.
