The Dynamic Of Wage Distribution In Chinese Taiwan

The wage income of labor force is the main source of income of workers.The wage income gap within a reasonable range is conducive to the flow of social wealth and economic development,while the serious wage income gap will affect the distribution of social wealth,leading to the deterioration of the gap between the rich and the poor,thus affecting social harmony and stability.Therefore,the study of the distribution dynamic relationship of wage and income level is helpful to explore the internal influencing factors of labor wage level,and is of great significance to narrow the gap between the rich and the poor and income redistribution.The research object of this paper is the density distribution function curve of labor wage income in Taiwan,which is the first time that the function type autoregressive model is applied to the study of the dynamic relationship of the density distribution function of labor wage income.Firstly,we select the micro survey data of labor wage income in Taiwan from 1978 to 2016,transform the discrete survey data into the density distribution function data by using the nuclear density estimation method,reconstruct the function data by using the basis function expansion method,and then construct the first-order autoregressive model of the density distribution function of labor wage income,and estimate the regression operator,The dependence test between the moment statistics of each order,explore the dynamic relationship between the density distribution function of labor wage income in each year,and finally predict the density distribution function of labor wage income dynamically.The main conclusions of this paper are as follows:(1)the dynamic change of the density distribution function curve of labor wage income in Taiwan of China is obvious,the mean value shifts to the right,and the variance changes in a "U" shape,which shows that the overall living standard is constantly improving,and the labor wage income gap shows a trend of decreasing first and then rising.(2)There is an obvious correlation in the time series of the distribution of labor wage income density in Taiwan,which is embodied in that the average wage level of the labor force in the previous year,the wage income gap of the labor force and the proportion of low wage groups will have an internal impact on the average wage level of the labor force in the next year.(3)The first-order autoregressive model of function type is established to predict the density distribution function of wage income.First,the curve of wage income density distribution function fitted in the sample is compared with the actual curve,and the result is good.Therefore,the model is used to predict outside the sample,and the curve of wage income density distribution function of Taiwan labor force in 2020 is predicted year by year.The prediction curve shows that 2020 In,the average wage income of Taiwan's labor force remained basically the same,while the wage income gap of Taiwan's labor force was still increasing.
