The institution of rigid rural-urban segmentation system and economic planning system is the starting point of China's labor market.These two institutions are intertwined with market mechanism.The consequence is that the evolution of labor market is not only combines with the most active parts of economic planning system and marketing system，but also creates multiple segmentation of labor market.According to the evolution ofhukou registrations ystem and China's ownership system，in this paper the following questions will be discussed by literature studying，establishing theoretical framework and empirical testing：how the evolution of China's labor market from 1949 to 2011?What's the feature of China's labor market evolution? Whether the China's labor market has the trend which isfrom segmentation to integration? And what's the theoretical rationale of China's labor market evolution? In the future，does the China's labor market go to integration? This paper research these three questions follow the review history，establish theoretical framework，and search empirical test.

Firstly，by studying the effect that the change of hukouregistration system and China's ownership have on the wage determination and labor force flowing，We find that the feature of China's labor market evolution is that under the impact of the market，the hukouregistration system and China's ownership，as the spindle of the evolution，have been changing from the status of almost complete segmentation to the multiple segmentation on the base of hukouregistration system and China's ownership system together with some other factors .

Then，having mixed the view of classic economic，institution economic and development economic for the labor market segmentation，we divide the factors that influenced labor market into three types which is the endogenous，exogenous and induced factors on the base of a clear concept of labor market integration.Then this paper proposes a tentative analytical framework.Using this analytical framework，we suggest thatChina's labor market shows multiple-segmentation state after analyzing these three factors on the background of China.In addition，we also suggest that this multiple-segmentation state is superimposed by“double-dual”segments（which is formed by hukou registration system and China's ownership system），endogenous segments，spatial mismatch and peer effects.And the economic behavior of individuals and firms will change multiple segment states.Following the classical searching and matching model proposed by Mortensen and Pissarides （1994，1999） and Pissarides（2000），we establish a two-side heterogeneous matching model to model“double-dual”segmentation state.The equilibrium of model shows that“double-dual”segmentation state results in multiple equilibrium existence.And there are two different wage determination mechanism and labor demand condition.Also，the equilibrium result has higher hire cost，employment cost，and labor force mobility cost.Dynamic analysis shows that the“double-dual”segmentation state has the trend of integration，but the higher labor mobility cost make“double-dual”segmentation state persistence in the long run.

Finally，this paper use the datasets of CHIPS（2002）and CGSS（2006）to analysis China's labor market segmentation state and its change from the view of labor force mobility and wage level respectively.Using switching regression model，we find that China's“double-dual”segmentation state is exist and endogenous and even is the barrier of labor force mobility.We also find that the degree of barrier of labor force mobility is：1）urban labor

It's the key point that achieves equal employment between rural and urban areas to break the barrier of labor flow among rural-urban，China's ownership sector and regions and wage inequality.Therefore，to improve the integration of China's labor market，the above mentioned institution barriers have to be got rid of.
