Abstract This paper analyzes the regional variation of minimum wage in China. We first introduce the institutional background of China's minimum-wage policy and then describe the regional variation of the minimum wages using detailed minimum-wage data since the late 1990s. A large regional variation exists in the period studied, and the regional variation has been declining since the late 1990s. Economic factors, including GDP, economic structure, and consumption level, are the main determinants for the large regional variation in the minimum wages. There is evidence suggesting that the regional variation is influenced by political factors, such as competition of local officials. Jel codes: J3, E2

This paper analyzes the regional variation of minimum wage in China. We first introduce the institutional background of China's minimum wage policy, and then describe the regional variation of the minimum wages using detailed minimum wage data since the late 1990s. Large regional variation exists in the period studied, and the regional variation has been declining since the late 1990s. Economic factors, including GDP, economic structure, consumption level, are the main determinants for the large regional variation in the minimum wages. There is weak evidence suggesting that the regional variation is influenced by political factors, such as competition of local officials.

RésuméLes auteurs observent que la prime aux qualifications a augmenté dans toutes les régions de Chine entre 1995 et 2002, mais seulement dans les régions côtières entre 2002 et 2007. Ainsi, ces régions présentent de plus fortes inégalités salariales, notamment en zones urbaines. Si les privatisations ont été la première raison de la montée de la prime aux qualifications entre 1995 et 2002, entre 2002 et 2007 cela a été l'intégration, inégale selon les régions, à l'économie mondiale. Réduire cette prime et les inégalités suppose de réformer le système du hukou qui fait obstacle à la mobilité de la main‐d'œuvre, donc à la croissance.

ResumenA partir de datos de encuestas de hogares, los autores observan que las primas por calificación aumentaron en toda China entre 1995 y 2002, pero solo en las provincias costeras entre 2002 y 2007, año en que estas también registraron mayor desigualdad salarial y contribuyeron más a la desigualdad salarial urbana total. Según un modelo de efectos fijos estimado, la privatización explica la evolución del primer periodo, y la integración de China en la economía mundial, la del segundo. Reducir la desigualdad exige, según los autores, la reforma del Registro de Población Hukou, que obstaculiza la movilidad de los trabajadores calificados y posiblemente también el crecimiento.

AbstractBased on urban household survey data, the authors find that skill premia increased significantly across all regions of China between 1995 and 2002, but only in coastal regions between 2002 and 2007. By then, these regions also displayed much wider wage inequality and thus contributed more to overall urban wage inequality than non‐coastal regions. While privatization was the main driver of skill premia in 1995–2002, China's (regionally uneven) integration into the global economy became the dominant influence in 2002–07. Reducing skill premia and inequality, the authors argue, calls for reform of the Hukou registration system which impedes skilled labour mobility and possibly also growth.

China has long aimed to restrict population growth in large cities but encourages growth in small and medium-sized cities. At the same time, various government policies favor large cities. We conjecture that larger cities in China have more urban amenities and a better quality of life. We thus predict that a typical rural-urban migrant is willing to give up some income in order to live in a larger city. We present a simple model in which rural-urban migrants choose destination cities to maximize utilities from consumption and urban amenities. Drawing data from a large-scale population survey conducted in 2005, we first estimate each migrant's expected earnings in each possible destination city using a semi-parametric method to correct for potential selection bias. We then estimate the typical migrant's preference for city population size, instrumenting population size with its lagged values to control for potential omitted-variables bias. From these estimation results, we calculate the typical migrant's willingness to pay to live in larger cities. Our results show that indeed rural-urban migrants strongly prefer cities with larger populations. We explore possible explanations for this preference and discuss the implications of these findings.

Using a 1/5 random draw of the 1% census of 2005, we investigate how China's higher education expansion commenced in 1999 affects the education opportunities of various population groups and how this policy affects the labor market. Treating the expansion as an experiment and using a LATE framework, we find that higher education expansion increased the probability of go to college tremendously. Different populations 'benefit' from this policy differently however. Minority female, those from central-western region and from rural areas are less likely to benefit from it. One-child families are more responsive to this policy. Using higher education resources at the provincial level as another dimension of variation, and using a difference-in-difference strategy, we find that the education expansion decreased the within sector inequality of population with above high school (inclusive) education. This is primarily due to the increase of the income level for high school graduate. That of the college graduate deceased, but only slightly and not significantly.
