The conclusion is that the path of Nanjie's institutional change is the outcome of the coevolution, say, competition, constraints, enforcement and transformation between the state and market; the coevolution have three dimensions: benefit, legitimacy and ideology; the path and outcome of institutional change in the process of coevolution are shaped by both the dual process of modernization and marketization in China's social transformation and the path dependence and cultural lag in China's incremental reform strategy: on the one hand, as historical conditions, the proceeding and logic of China's modernization constraint the state and market's institutional choices; on the other hand, under the interplay between the path dependence and cultural lag, the interaction between the state and market can produce various complex combinations, therefore various institutional landscape, even "institutional paradox".

In history and reality, the contradiction between needs and limited resource always exists. From the view point of system-science, it can be concluded that:①The interaction among need-contradiction-ability is the perpetual force for enterprise evolution (and the evolution of other living systems). The improvement of "ability"is the process and result of evolution.②The competition and coordination among systems is the direct power for enterprise evolution. Competition produces various system actions. Coordination makes systems complement their functions with each other. The interactions of competition and coordination push enterprise into the flow of evolution and optimization.③The"stochastic fluctuation"of the system, which is accidental finding, is another force for enterprise evolution. It is a deterministic element in the process of the self-organization of enterprise.
