China's development zones are new things to break through the traditional planned economic system since birth. The system of their management has made many fruitful achievements in the process of moving to- wards the target mode of modern market economy

especially the systems and mechanisms of operation and management of small government

big society

small institutions

large service

which not only brought more efficient development for those development zones but also brought great economic and social benefits. Current- ly

China 's development zones are at a crossroads

which indicates that those development zones

during their transitional period

are facing various realistic contradictions and conflicts that are mainly related to these new problems such as industrial upgrading

land bottleneck

debt risks

conflicts with the mother city and conflicts be- tween management and administrative systems

as well as social service and community governance. This paper studies those problems not only from structural factors but also from the multiple dimensions and systematic analyses of the realistic problems of transitional development of the development zones and their systems of management. With the basic target mode of giving full play to the decisive role of the market in the allocation of resources and better playing the role of government

the paper analyzes the solution of important problems such as what is the essence of the development zones

how to reduce the functions of the market and the govern- ment in the systems of management

how to allocate the function of social services

how to form the mechanisms of co-governance by communities

and how to overcome the problem of compact development of the land bottle- neck of development zones

intensive and group development of the industrial bottleneck

and management mode of the division of labor and governance in solving conflicts with the mother city.
