Market-oriented reform has injected impetus into the free flow of labor in China and promoted economic growth in the past. However

it is still a question whether China's labor market structure can meet the new demand for the free flow of labor in the New Normal. Drawing lessons from the market transformation theory

relevant arguments

modernization theory and other theories

this study infers that China's labor mobility networks not only have the characteristic of free mobility

but also demonstrates the free mobility advantages of system division

of the public unit labor sector

and of the modern labor sector. This study uses CLDS2012—2018 and CFPS2012—2018 data to construct China's labor market sector mobility networks of the whole period and of three rounds

and finds that these networks demonstrate an aggregation-segmentation structure with unit aggregation as the major characteristic and industrial aggregation as the minor characteristic

together with the small-world and scale-free characteristics. The results of ERGM model show that reciprocal flow

related preference dependent flow and transfer flow are significantly positive

and the coefficients are getting larger and larger

which reflects that the small-world and scale-free characteristics of China's labor market sector mobility networks are getting stronger while its network segmentation characteristics are getting weaker. This shows that under the impetus of market-oriented reform

China's labor market is becoming more and more open. However

the obvious advantages of system division and public unit sector are still very strong

which means that there is still a long way to go to deepen the reform of the labor market system. At the same time

this study also finds that the modern labor sector is rising in the labor market mobility networks

which deserves more attention.
