| CNC machine is a primary machine tool of equipment manufacturing industry. It is one of basic, pillar and strategic industries in the economy of China. Meanwhile, it is the criteria to evaluate a country's comprehensive national power and the degree of industrial modernization. Some industrial advanced countries look CNC technologies and equipments as national strategic resources. They not only try their best to develop CNC industry, but also block and restrict high-grade, precise and advanced CNC key technology to spread to developing countries. Our country has been paying a lot of attention to the development of high-end CNC machine industry.《National Guideline on Medium-and Long-Term Program for Science and Technology Development (2006-2020))) confirmed "high-end CNC machine tools and basic manufacturing equipment" as one of sixteen national science and technology programs, and defined the breakthrough of technology in the filed of heavy-duty and large-size CNC machine tool industry as the key to the high-end CNC technology development.Driven by the national policies, CNC machine tool industry has become a new opportunity for economic growth in Hubei Province. Specially, Wuhan Heavy Duty Machine Tool Group Corp., which is an enterprise model of Hubei's CNC industry, held a leading position in the national field of heavy-duty and large-size CNC machine tool. However, due to some factors affecting CNC machine tool industrial development, such as market reforming, market competition and so on, heavy-duty and large-size CNC machine industry in Hubei still needs improvement. We must face a series of questions. For example, how to establish effective development strategy to boost up its technological capabilities and to promote economical development in Hubei is the main problem to be solved. A technology roadmap (TRM), an efficient management tool, is developed from the view of customers to foresee and choose critical technologies for companies. Recently, TRM is popular in American, Japan and UK, and other developed countries, and it is proved to be of great help. However, few research and practical guidelines are offered in China. Accordingly, the main purpose of this paper is to study industrial development strategy on heavy-duty and large-size CNC machine tool industry which has become a pillar industry in Hubei, based on a general idea of technology roadmap, including market demands, industry aims, technological barriers, R&D needs, and resources. Specifically, the content can be abstracted as follows.(1) Based on reviewing the theory of technology roadmap, this paper first illuminates background and developing process of heavy-duty and large-size CNC machine tool industry, and analyzes the development of heavy-duty and large-size CNC machine tool industry in Hubei with consideration of industry environment, industry resources, and industry relevancy. The above work sets up a heavy foundation for the following research.(2) On the foundation of general analysis of heavy-duty and large-size CNC machine tool industrial demands in Hubei, this paper recognizes demand factors using group decision making method based on triangular fuzzy numbers. Subsequently, the technology roadmap on demand factors is drawn to illuminate the trend and driving force of industrial development, and to determine the industrial position.(3) According to overall analysis of industry aims and technology development trend of heavy-duty and large-size CNC machine tool industry in Hubei, expert visiting method and principal component analysis are employed to analyze the relevancy between market demand factors and industry aim factors to identify the aims of the industry. And then the technology roadmap of industry aims is drawn as a basic reference to select industrial innovation strategy, to determine the organizational management of technology innovation and R&D plan.(4) To recognize the key technology for heavy-duty and large-size CNC machine tool industry in Hubei, we proposed a patent document analysis method based on XML. With this method, key technologies are found out by analyzing patent documents and the technology roadmap of industrial key technology are finished. This roadmap helps to acquire the trend of new technology, and thus to select projects with priority, which provides guidelines to optimize the allocation of science and technology resources.(5) Based on the key technology recognized of heavy-duty and large-size CNC machine tool industry in Hubei, this paper selects R&D projects and defines their priority. Using improved risk matrix method, the risks of prima R&D process are analyzed, and the risk-profit technology roadmap of prima R&D projects is done. Then, this paper analyzes R&D main body and model to manipulate the TRM of R&D risk, R&D body, and R&D model. Furthermore, considering its resources demand, the paper evaluates the industrial R&D resources objectively with the method of SWOT-AHP.(6) Summarizing the technology roadmaps of market demands, industry aims, technological barriers, R&D needs, resources etc., the paper draws the comprehensive TRM of heavy-duty and large-size CNC machine tool industry in Hubei. It further puts forward the general ideas and suggestions on industrial development, providing reference for the decision making and strategy selecting of the industrial development.
