| Abstract: | Based on the perspective of sustainability transitions(ST) theory, the paper dissects the opera-tional mechanisms of protected space driving emerging technology industrialization from an external system perspective, which is on the basis of defining essential characteristics and func-tional attributes of protected space. Meanwhile, it structures a three-dimensional evaluation model of protected space from the perspective of internal mechanism by introducing the policy mixes method.Finally, taking the Chinese New Energy Vehicle(NEV) industry as the example and using the system dynamics modeling method, the paper designs different simulation schemes from three dimensions of horizontal evolution trend, three types of policy instrument change and policy mixes of protected space,to predict and analyze the operation effect of protected space. The results show that the Chinese NEV industry is in the stage of market niche entry, and corresponding measures should be taken to increase the market scale, form effective demand and scale effect, and promote the diffusion of market niche;the effect of policy mixes is better than that of the single policy instrument; specific policy mixes should be adopted to develop simultaneously from both the supply and demand sides to improve the industrialization level of NEV. |
