Analysis On The Change Of Population Age Influences The Supply Of Work Force

Since we put reform and open into practice, the development on the economics of our country has been faster and longer time. The activity of the economics has been stronger. All the above change pulls the requirement of being employed. On the other aspect, the speed of urbanization increases. The structure of urban population changes, the type of people reproduction changes and ration of labor age population become higher in the meantime of the increase of population number, the window of"population bonus"has been opened. When we think that the coming of"population bonus"create the positive factor of our country's social economics, the phenomenon of"barrenness of civilian worker"appeared in the area of Zhujiang delta in 2004, this phenomenon spread to the other area of China quickly, the western province, outputting the work force, widely appeared the problem of work force shortage in 2007. My thesis is from the change of population age structure to analyzed the current of condition about work force, and I also made a forecast of the development on future, I set forth the problem of work force supply in the development of economics, and I made out the method of how to deal with the problem.Totally speaking, my thesis can be divided into four parts.In the first part, I explained the related definitions and theories of work force, the significance of dealing with the work force supply, basic definitions and basic theories. I explained the problem of work force briefly, emphatically set forth the work force, Luis turning point, labor age population, the quality of work force supply, population bonus, labor supply, etc. I analyzed the problem of work force supply through the theory of population and work force & work force supply.In the second part, I analyzed the change tendency of population age structure in China. I introduced the change and current condition of population age structure in China since the reform and open. I predicted and analyzed the number of population, the current condition of work force age population and future development. The result of the prediction shows that work force age population decreases and the aging work force age population.In the third part, I explained the influence between population age structure and work force supply. Firstly, I analyzed the current condition of work force age population, I analyzed the current condition of work force supply from the weak tendency of increase on work force supply and improving the quality of work force supply. Then I analyzed the change of population age structure influencing the supply of work force. I explained it from three parts, the unbalance of ration on sex, the tendency of change on population age structure and the quality of work force. At last, I analyzed the factors of work force supply influencing. I mainly from two aspects, one part is the factor of economics, low salary high price restrain the work force supply, the increase of agriculture attracts the work force reflows, the work force supply decreases, the development of unit derives the increase of work force, I analyzed form the above aspects. Two part is the factor of society, duality structure of nation and the country, the social phenomenon of work force, the legal interests work force, government function influences the legal interests.In the fourth part, I put forward the methods of the problems about the change of population age structure influencing the work force supply. Based of the above analysis, the decrease the work force supply can influence the social economics in three aspects. One is the development of the third of industry, two is the development of economics between city and country, three is the output of labor intensive industry. Following the increase of economics, work force shortage, all of these induces the labor intensive industry and partly service industry ( for example, building, assembling, home economy, retail, dieting, etc.) shortened the work force supply, increasing the salary cost, influencing the equipping of producing factor effectively, influencing the development of labor intensive industry and the third industry. In order to decrease the influence between future work force supply decreasing and the influences of economics, I put forward the methods from the three aspects: upgrading industry structure, adjusting policy institution, adjusting the strategy of the development on unit and improving the quality of work force.Last but not least, my research showed that the number of future work force supply in China will come to the summit in 2025, the number of work force supply can come to the summit between 2020 and 2025, taking precautions before it is too late, we must put forth the decrease of work force supply, in order not to influence the social economics in China.
