The paper defines industrial cluster general purpose technologies (or generic technologies) according to the literature review regarding generic technology. Based on its definition and cluster perspectives, three methodologies of choosing industrial cluster generic technologies from industrial chain dimension are proposed, that is, horizontal analysis, vertical analysis, and cross analysis. Jiande hardware and electronic appliances industry, Anji chair industry, and Hangzhou equipment manufacturing industry are empirically analyzed via these methods, which leads to the conclusions: (a) choosing cluster generic technology should be underpinned by industrial chain analysis; (b) the common technology utilized by cluster may not be public goods, which implies that it can be levied on enterprises within the cluster; (c) supply and organization of generic technology may differ depending on the industrial chain structural distinctiveness.
