From the perspective of green transportation, this research chose Dongguan “motorcycle ban” policy as the research object, and constructed secondary evaluation index system in transportation and environmental harmony, transportation and future harmony, transportation and society harmony, transportation and resource harmony, four dimensions. Then it used fuzzy comprehensive evaluation model to do the evaluation and found that the policy’s positive effect on the Dongguan green transportation development was average. Finally, based on the evaluation results, measures and advices were proposed.展开更多

Our study suggests the followings. First, under the previous unchanged family planning policy, current deficits and cumulative deficits will occur in the social pooling fund in the year 2047 and 2063 respectively. Second, if lO% to 50% of qualified couples choose to raise a second child, the financial status of the social pooling fund will improve; relative to the previous unchanged family planning policy, the contribution ratio can decrease from 20% to the range between 18.06% and 19.57% without causing any changes to the original financial status of income and expenditure. Third, if the percentage of couples choosing to raise a second child rises to 60% to 100%, the contribution ratio can even decrease to the range between 16.55% and 17. 7% without causing any changes to the financial status as under the previous unchanged family planning policy. The above conclusions have all passed the sensitivity test. Therefore, the ＂two-child policy＂ for qualified couples is favorable to alleviating the payment pressures of pension insurance but the policy effectiveness is subject to fertility desire and the intensity of government implementation.展开更多

Based on the forecast of total population change in national and provincial dimensions after the two -child policy, the paper forecasted the spatial pattern of China's population and provincial differentiation over the next 15 years, and discussed the far-reaching impact on the future urban and rural land use and planning. Conclusions as follows: the two-child policy will achieve rapid population growth in the next 5 years, then there will be a stable growth phase;the peak of China's population increase will occur in 2030 with a total population of about 1.55 billion people, which will continue the regional differentiation of urbanization, and urbanization level in southeastern region will remain generally higher than that of the northwest. In addition, population growth brings new demands in urban and rural construction land, therefore, more intensive use of land will be the inevitable choice for the future development for China.展开更多

Female couples can have a policy of giving birth to two children. On October 29, 2015, China introduced the ＂two-child policy＂, completely replacing the ＂one-child policy＂ that has been implemented in China for more than 30 years. The ＂two-child comprehensive＂ can alleviate the unfavorable population trend that plagues China＇s social security system to a certain extent. Optimize the age structure of the population and increase the supply of labor. However, for a long time, the financial distress and management dilemma faced by China＇s pension payment still exist, and the loose population birth policy will have a great impact on reducing pension payment, and will gradually appear in the policy implementation. This article combines the ＂comprehensive two-child＂ policy, focusing on the role of the new population birth policy to alleviate the pressure on China＇s pension.展开更多

With its implementation, the country’s total population will peak later, the underage population and its proportion will increase substantially, the working-age population will experience a slower decline, and the aging of China’s population will be eased. However, the drop in the proportion of working-age people over the last 15 years has expedited the reduction of the demographic dividend, the elderly population will remain unaffected over the next 60 years, the aging of the population will continue to deepen, and at the same time, the increased child dependency burden will expand the overall dependency ratio.展开更多

Based on the questionnaire survey of influencing factors about professional women＇s intention of second child birth and with two child policy was carry out as the background, summed up the three major factors influencing the working women fertility fertility intention, emotional factors and external security. At the same time using the structural equation model, studies the impact of the influence factors to the career development of working women. The conclusion is that childbearing willing has little effects on the professional women in Shanghai, emotional factors and external security has certain impact on women＇ s employment.展开更多

However, for a long time, due to the historical and social impact of many factors, college physical education work is far from being universally recognized. College physical course consists of theoretical physical education class and sports practical classes composed of only two courses in order to achieve common development goals college physical education. At present, although the theory of physical education teaching experts made a number of proposals for reform, but did not form a complete teaching system, which leads to the problem of teaching the theory of college sports programs still cannot get solved. We studied sports teaching evaluation system, describes the theoretical basis for building efficient sports teaching appraisal system, and analyzes the constituent elements of the evaluation system.展开更多
