Quality of life can be evaluated through multiples angle of view,multiples dimensions and multiples groups.The theories of economics and sociology give us the methods to analysis the present status of life quality.The development of science and technology have closely related to the quality of life improving.Statistical theory and methods can be used to analysis and give a whole picture,that maybe reduce the estimate error come from personal opinions and the government policy.
The system of national accounts is a public product with non-exclusivity and non-competitiveness,which is also the a kind of institutional arrangement of international statistical systems and macro-economic statistical information.It does not fully state China's theories and practice of national accounts,but complements cognition of model selection,knowledge production and system construction of China's national accounts.It shows that,firstly,the reform starting point of China's statistics is the indicator of 'output value' using MPS boundary and China has never systematically carried out the MPS.The transformation and reform is the integrated results of domestic motivation and international pressure.The development of China's accounting practice is not balanced and currently located between SNA1953 and SNA1993 with part of items are approaching SNA2008.Secondly,the contribution of China's scholars in SNA area are in three aspects:introduction,interpretation,and localized exploration.The knowledge of SNA is related with national economic safety and quality improvement.China's scholars should devote their efforts in the SNA research to improve our social infrastructure.The SNA concept is provided which emphasizes the further theoretical law and methodology research.Thirdly,the limits of SNA itself and China's high-quality development require SNA to further research and development.Also,China's track of SNA system is constructed and systematical development path is issued.
This paper is that to study about the relation between earning management and large shareholder,illustrates the role of institutional investors in corporate governance from the perspective of the how to effect between large shareholding control and the earnings management of listed companies when institutional shareholding.In Shanghai,Shenzhen A shares listed companies in 2007 to meet the research requirement of corporation governance and financial data for the study of data,through the establishment of research hypotheses and research model,through empirical test.The study finds that with the shareholding ratio to a level of 6% as the boundary.when the shareholder ratio of institutional investors is high,institutional investors can inhibit the large shareholder control on manipulation of earnings management,When the proportion of institutional investors holds low,it could increase manipulation of the large shareholding control to earnings management.
The prediction of financial time series is one of the hot researches in finance.Based on the existence of weak chaos in financial market,we make an empirical study on prediction of Chinese financial market based on the recurrent predictor neural network(RPNN).We train the network by using genetic algorithm(GA) to optimize the weight and threshold,also the amplitude and slope of the excitation function.We test some typical varieties of Chinese stock market,futures market and gold market.Two performance measures(root-mean-square error(RMSE) and prediction accuracy(PA)) are calculated and compared to two classic neural networks-back propagation neural network(BPNN) and radial basis function neural network(RBFNN).The result shows that the proposed method is more effective and accurate.
In this paper,a dynamic stochastic general equilibrium(DSGE) model is presented,which incorporates the capital quality index into the process of capital accumulation.The parameters are calibrated according to the economic features of Shaanxi province.The difference of influence on the macroeconomy are compared between a neutral technology shock and a capital-embodied technology shock.The conclusions show as follows.The impact of neutral technology shock responses to consumption and wage is shown to be positive while the impact of capital-embodied technology is proved to be negative.But the effect of capital-embodied technology shock on reducing the capital rent rate appears earlier.The capital-embodied technology shock has a significant growth effect on total output due to the intertemporal choice of consumption and the increase of labor supply.Compared with the single tax reduced policy,the instant fluctuation of investment is reduced significantly,and the variation in tax and output are stabilized due to the coupling effect of the tax reduction policy and the policy which promote capital-embodied technological progress.Additionally,the consumption is prompted to return to a new steady state more quickly.At last,some suggestions are proposed.
According to the 2008 survey data of the consumption on dairy productions of urban residents in Xinjiang Uygur Autonomous Region,and utilized the Path Analysis Model,this article analyzes the influence factors on dairy production's consumption.The survey shows that the individual income and consumption habits have positive influence to dairy productions consumption,and the demographic characteristics,such as gender,age,nationality,occupation,education,family size etc.,also have some influences.This article indicates that it is important to improve the nutrition knowledge of dairy production,to help the residents to build up the dairy consumption habits especially for teenagers and to increase residents' income and favorites to dairy productions.This article also encourages the enterprises to produce more varied productions with differentiation on taste,price and localization to meet different group's consumption needs,to improve the logistical system and make more efforts to develop the markets of small city and town.
