Wage income is the most important income of common families and closely related to the livelihood of the people and social stability of a country. It is because of such importance of wage income that international conventions and relevant production regulations have clearly defined that wage paid to employees must be at least the minimum wage that can guarantee the basic needs of employees be satisfied. According to the Minimum Wage-Fixing Machinery Convention (1970) and the Minimum Wage-Fixing Machinery Recommendation (1970), International Labor Organization (ILO), minimum wage shall be fixed by considering the following factors: 1) The needs of workers and their families; 2) Total wage level of the entire society; 3) Living cost and changes; 4) Social security allowance; 5) Production standards of other social classes; and 6) Economic factors, including requirements on economic development, productivity, wishes on realizing and maintaining high employment rate, among others. In most countries, minimum wage is fixed by considering the factors above-mentioned and the paying ability of employers.
However, many governments did not show a clear attitude to consider such factors when fixing minimum wage. Some governments in developing countries, for example, attached higher priority of economic growth above workers’ benefits and rights and considered minimum wage a factor impeding their competitive advantage. This is why the minimum wage fixed by some governments cannot satisfy the basic needs of workers and their families. Such minimum wage does not reflect inflation and other factors that affect life quality of workers. In some countries, the government is lack of initiative in enforcing minimum wage standard, and workers have to work overtime to earn legal minimum wage.
In recent years, the Chinese government has been working hard to increase individual income of the Chinese people through increase of minimum wage, solving problems on arrears of wages, decrease of interest rate of bank deposit, and increase of personal income tax cutoff point. However, the disposable income the people, particularly those of the low-income class, remained at a relatively low level.
According to the social bluebook published by the Chinese Academy of Social Sciences in 2008, although the national economy and GDP of China kept increasing, the proportion of wage in national income was decreasing year by year. Before 2003, the proportion of wage in GDP was more than 50%. However, it dropped to 49.6% in 2004, 41.4% in 2005, and only 40.6% in 2006. It is clear that there is a tendency of decrease of the proportion of wage in primary distribution and an increase of capital income. This phenomenon is called “wage corrosion by profit”. Some experts pointed out that for the future development of China, it is preferable to establish a high-wage economy, but not a low-wage one. Therefore, increasing proportion of labor income in primary distribution and letting more people enjoy the benefits of economic growth are of great significance for development of China and maintaining a stable society.
