Effects of Changing Relative Value of Mininimum Wages on Wage Distribution in China:Analysis Based on County-Level Data

On the basis of extending Lee's(1999) model, this paper resolves the problem of biased division in the specification of equation and employs Urban Household Survey(UHS) data,China Household Income Project(CHIP) data and county-level minimum wage data collected by authors to investigate the wage distribution effects of change in the effective minimum wages measured by relative value. The result shows that the effective minimum wage will exert a significant spillover effect on wage distribution at the40 th percentile and below, which is favorable to reducing wage gaps at the bottom. This conclusion holds true under various robustness tests. However, the shrinking effective minimum wage has created a downward drag on wages, thus widening wage gaps at the bottom. The shrinking effective minimum wage contributed 150%,53.8%,45.5% and16.7% to the wage gaps at the 10 th, 20 th, 30 th and 40 th percentiles compared with the 50 th percentile. Therefore, the key to ensuring the effectiveness of minimum wages lies in the implementation of an automatic adjustment mechanism correlated with macroeconomic indicators. Compliance with minimum wages must be guaranteed and change in minimum wages must be measured with relative value.

The Economic Effect of Mineral Resources Exploitation in Bijie Prefecture in Guizhou

The exploitation of mineral resources plays an important role in promoting national economic development. Mining is an essential component of China's industrial economy. Using grey correlation method to analyze the correlative effect of mineral resources exploitation to relevant industries, using national income method to calculate the pulling effect of mineral resources exploitation to economic growth and using graphs as well as tables to analyze the income distribution effect, the article obtains active economic effect of mineral resources development in Bijie, Guizhou. Moreover, from the view of resources-cored effect, the article analyzes negative effects such as single industrial structure brought by mineral resource development. Through analysis, we find that mineral resources exploitation to some extent brings active effects including gross domestic product growth, local financial revenue growth and relevant industries development; however, its negative effects should not be ignored. The negative effect can be lightened by diversifying industrial structure and prolonging industrial chain.
