Study On Economic Development, Aging Population And Social Security

With the economy development of more than 30 years, China has been the second place in the economy world. Although the average GDP per person all over China is 6,747 dollars, the average GDP per person in 11 provinces have been about 10,000 dollars, such as Tianjin, Beijing, in 2013.On the other hand, China has been an aging old society since 2000. At the same time,”One child” policy rose greatly the old age dependency rate. The economy development and aging population of China, now, is mostly same as the situation of OECD members in 1980 s. How to deal with the economy development, aging population and social security is probably the same question between today’s China and 1980s’ OECD. So, this article tries to analysis OECD members to find the general rules of social security during the situations. Further more try to offer some basic practical rules for the social security of China.As with the details of study way, firstly, this article make a theoretical analysis of economy development and social security, aging population and social security, secondly, introduce separately the social security situation and specialty both of OECD members and China. And then, we search the all kinds of data in OECD members between 1988 and 2007, and make an econometric model to analysis the influence factors of social security. On the base of different systems of social security, the paper focuses on analyzing the relationship between economic development, aging population, and social security. We get the main conclusions: 1.In social insurance countries, the increase of GDP per person will make contribution to improve the social security, while it will decrease the level of social security in welfare countries. 2. Aging population is positive related with social security under two kinds of models of social security system, but the effect is bigger in welfare countries than in social insurance countries. 3. The increasing of saving will have a negative effect on the increase of social security level, no matter which social security system the OECD members choose. 4. The fixed investment has different effect on social security under different social security system models. 5. Different social security system models will affect some important elements, such as, social security, fixed investment. Further more, it will have an effect of social security. At the end of this article, on the basis of the conclusions and the practical situations of China, we get two leanings. Firstly, under other variables stay stable, when GDP per person of China arrive 1,000 dollars, the increasing of 1 percent point of GDP will cause the increasing of 0.02 percent points in social security. Secondly, the aging population will occupy 12.18% all over China, and the social security level will accordingly be 9.44% at least. In a similar way, the aging population will be 24% of China, and the social security level will be 19.99%. At last, from the inspiring and learning of OECD members, we put forward some suggestions to the following development of Chinese social security.
