China's economy has entered into a New Era，with the economic transformed from high speed growth to high quality development.Improving high quality development is the radical requirement of today and tomorrow to confirm development thread，to make economic policy and to implement macro control.
At the same time，as the report of the 19th National Congress of the Communist Party of China has mentioned，the main contradiction of our society has transformed into the growing demand of people with the unbalanced and insufficient development.The balance of labor market directly impacts the overall economic activity.Labor market is the market where the production，exchanging and allocation of labor factors happened.Meanwhile，the combination of labor and capital decided the border of production activity.As a result，the labor market has a direct influence on the overall economic balance.The unbalance of labor market reflects the incomplete and discordance in the process of labor market development，which includes the demand and supply of labor，the relative price of labor factor，the mobility of labor and the government intervention.
Forty years since the reform and opening-up in China，the supply of labor has turned from structural surplus to structural shortage，the shortage of high skilled labor and the unemployment of low skill labor coexist.Meanwhile，labor market segmentation is a big obstacle of the one price law of labor.There exists distinct income gap between rural and urban，among different regions and different industries at a high level.Moreover，the mobility of labor is decreasing gradually，the barrier of household registration system on labor mobility is still obvious.Finally，the labor market regulatory policies have made great progress，social insurance has covered all labor in general.However，the level of social insurance is still unbalanced.These four problems mentioned above reflects four main content of labor market unbalance and impact the goal realization of the balance and sufficient economic development.
