| A moderate income gap is reasonable,but if the income gap is too large,it will cause laborers to concentrate on high-income sectors,resulting in high unemployment and imbalanced industrial structure;there will be two levels of income differentiation,two levels of consumption,and lower household consumption level;will impact the social equity system,combat production enthusiasm,and even endanger social stability and harmony.At present,China's total income gap far exceeds the international warning line.The government's income distribution policy has limited effect.The industry's income gap is at a high level,with only a small oscillation.The industry-level income gap is highlighted by the Matthew effect.The growth rate of low-income industries is not as high as that of high-income industries,and the income gap is deteriorating.The industry income gaps in the four major economic regions show significant regional differences,and the effects of the same influencing factors are also different in different regions.With the continuous opening up of the outside world,the industrial structure continues to be optimized and upgraded,and the market-oriented reform of the economic system is becoming more and more perfect,the income distribution system needs to be adjusted with the times to control the income gap of residents.Research on the key factors affecting the income gap in the open economy environment has great practical significance.Firstly,this paper combs the measurement methods of industrial income gap,employment structure and other indicators,and analyses the current situation of industry income gap in China.Secondly,the paper analyses the mechanism of the influence of opening up and employment structure on industrial income gap.Thirdly,this paper takes the open economy as the big environment,and takes the income gap of 19 industries in China as the research object.Based on the research results at homeland and abroad,the data of 30 inter-provincial administrative units in mainland China except Tibet are selected from 2003 to 2017.Using the Theil index to describe the industry income gap,using the industrial employment structure,skill employment structure and ownership employment structure to describe the employment structure,empirical analysis of the impact of opening up,employment structure on the industry income gap,and analysis of the opening up and employment structure integration effects and the regional differences in the effects of various influencing factors.Finally this paper gives the following conclusions:(1)The change of industrial employment structure has a significant impact on the industrial income gap.The direction of action is related to the adjustment direction of industrial employment structure.When the labor is sufficient,the transfer of the first and the second industry to the tertiary industry significantly expands the income gap.(2)The general improvement of the skill level of workers,especially the improvement of the basic skills of workers with low skill levels,can significantly narrow the industrial income gap.(3)State-owned enterprise employees remove the status of state-owned enterprises,and accepting a market-based compensation system will increase the industry income gap.(4)The degree of openness can significantly affect the income gap of the industry.The adjustment of trade structure and foreign-selected industries may cause a positive or negative change in the impact of opening up on the industrial income gap.(5)The higher the level of economic development is,the greater the income gap in the industry is.Inter-provincial mobility of labor and technology will increase the industrial income gap,while inter-provincial flows of capital can reduce the industrial income gap. |
