Minimum wage standard adjustment and employment: Heterogeneity effects on the human capital investment

Considerable debate has arisen around the potential effects of increasing the minimum wage on employment. This study aims to analyze the impact of changes in China's minimum wage standard on employment. The research utilises the canonical model method and constructs a regression model based on standard labor economics theory. The analysis is conducted using sample data from Chinese industrial enterprises between 2000 and 2007. Regression analysis is performed by categorizing enterprises based on their level of human capital investment. The findings indicate that minimum wage increases have a non-linear impact on employment, when seen from the standpoint of human capital investment. When the level of human capital investment is low, an increase in the minimum wage standard leads to a decrease in employment; when the level of human capital investment is high, an increase in the minimum wage standard leads to an increase in employment. According to the findings, the reason for this is that, investments in human capital can improve business profitability, increase worker marginal productivity, and increase labor demand. Similarly, the employment effect of a change in the minimum wage is positive in regions with high levels of human capital investment due to the externality effect of human capital. Adjustments to the minimum wage have a negative impact on employment in areas of the country with low levels of human capital investment. This demonstrates that changing the minimum wage does not result in a simple increase or decrease in total employment. The level of investment in human capital within the organization and the region is an important factor in determining the type and magnitude of the impact.
