With the deep development of the urban and rural, rural residents＇ living style has changed profoundly on the labour, consumption, entertainment, marriage and family, etc., and the differences of living style between the urban and rural are becoming smaller and smaller. Therefore, this paper suggested to promote the rural residents to build the scientific, cultural and healthy modern life style, and put forward the rational development thoughts.展开更多

An estimation method for kill probability is proposed, which solves the probability of number of residence times satisfied effective shooting in given time. Some expressions and their approximate formulae of kill probability are derived, under known the distribution of residence time series. Theoretical analysis and simulation results show that this method is suitable for evaluating the hit ability of fire system for maneuver targets in random shooting.展开更多

In order to get rid of the impact, the expansion of domestic demand has been a crucial means of steady economic growth in China. However, the farmers over seven million account for a large proportion should be the main consumers in China. On the contrary, the current lack of domestic demand in China, which is mainly in rural consumption, is the lack of the critical issues of our efforts to expand domestic demand. This paper clarified the factors restricting China rural residents＇ consumption demand expansion, and on this basis explored the expansion of rural residents＇ consumption demand countermeasures. Empirical analysis was used to prove the low level of income of rural residents＇ constraints, and also to expose the fact that social security system was imperfect. Meanwhile, rural infrastructure restricted the consumption level of rural residents. The consumer market is an effective way to improve rural residents＇ consumption demand.展开更多
