Innovation policies play an important role throughout the development process of emerging industries. However, existing policy studies view the process as a black box and fail to understand the policy-industry interactions through the process. This paper aims to develop an integrated technology roadmapping tool in order to facilitate the better understanding of policy heterogeneity at the different stages of new energy industries in China. Through the case study of the Chinese wind energy equipment manufacturing industry, this paper elaborates the dynamics between policy and the growth process of the industry. Further, this paper generalizes some Chinese specifics for the policy-industry interactions. As a practical output, this study proposes a policy-technology roadmapping framework that maps policy-market-product-technology interactions in response to the requirement for analyzing and planning the development of new industries in emerging economies (e.g. China). This paper will be of interest to policy makers, strategists, investors, and industrial experts.
