From the view of industry's technological development trend, the basic theory researches and technologies were sprouted by advanced developed country in Europe and USA. The technical and practical application of these researches and technologies were developed by Japan. By the way of cost down, mass production was made in developing countries such as Taiwan and Korea. In order to reduce the manufacturing worker and workspace cost, most companies moved to under-developed countries such as China and Vietnam, etc. These industry companies are including textile, shoes, petrochemical, PCB, IC and LCD manufacturing companies. In recent years, the modern techniques countries such as USA and Japan paid a lot of attention on the influence power of China and neglected Taiwan and Korea. In order to reduce operating cost and aim at the consumer markets closed to 1,300 million people, they entered China and set up the factory directly. How should domestic small and medium-sized enterprises in Taiwan respond to this situation? When the small enterprise using specialization to overcome the problems such as small-scale and lacking-resource, the companies had cooperated with the flexible attitude to deal with the change in situation in order to stand firm gradually and make a profit steadily. At this moment, the companies have already built and constructed the key ability. They tried to improve rate of production, increase enterprise's income and gross value, desalinize the prosperous circulation fluctuation and disperse the risk. Except expanding the service stations and developing key technology, the companies turn a means with much angles of relevant technology and enter the potential profit pool to set up the second and three pillars in order to adopt many angle actions to extend the goals and get involve into the new business field. Meanwhile, the main methods used is to expand from the key ability of most manufacturers in the course of growing up. In the key process of expansion, it is the important topic to have key ability and levelage accurately reach new technology, new product and new field. The motive of this research combines the practical experience of the industry and relevant references. It also discusses the enterprise with key technology to make the environmental analysis, tactics of industry plan and execution in different business. The key succeed factor and failed reason is also compared to provide as the reference which company or the new undertaking of relevant industry's future assess of the cases to reduce the investment risk in the future and increase the probability of success. The main purpose of this analysis can be summarized as following: 1. The case study of the company is based on key ability to make different management tactics analysis that technology is correlated with. 2. In the case study of multi-business, it is analyzed and summarized on the key factors of the successful and unsuccessful cases. 3. Give some suggestions as the reference for the company or the relevant industry's factory to develop new business. In this investigation, the resource basic theory, multi-business motive and key successful factor are used to analyze the small and medium-sized enterprises that can create relevant technology for multi-business management. One precision coating professional manufacturing company is studied and analyzed by its tactics and key successful factor. In the results of this study, one can find that the company keep far from core ability during the process of multi-business operation will cause automatic control parameter lower and external variable larger. It leads the probability parameter of success to be smaller and difficult to master with greater risk. While getting into the new business, it will increase the success probability if one can integrate the upstream and downstream industry chain at the same time. Especially, the company obtains the support of original supplies or main customers with key raw materials and technology will develop the specialization and characteristic to make better profit.

經濟、社會的轉型促使百貨公司的經營型態也隨之改變，再加上百貨公司這些年受到購物中心、專賣店、郵購、直銷等通路的崛起，以及百貨產業內本身的競爭，造成內外夾擊的情境。所以研究動機為如何能讓自己在競爭的環境中處於不敗之地，邁入新世紀正是每位百貨經營者亟需思考的地方。另外中型百貨公司應該以何種經營策略才能面對大型百貨公司競爭時，仍有獲利、成長的可能性。 本研究的架構係採用Aaker的理論架構來進行內外在分析與策略規劃。整個研究架構分為四個階段：一、首先進行內外在分析，以界定外在環境中的機會與威脅，以及該產業的關鍵成功因素，並了解個案公司所擁有的優劣勢。二、根據以上分析，歸納出該公司所面臨的問題。三、擬定數個可行的策略，在該策略下擬定競爭策略與營運策略，然後依照適當的準則予以評估予選擇。 經過本研究分析後發現國內百貨業的關鍵成功因素為：營業商圈的特色、建立屬於自己的特色、提供顧客所需商品及全方位的服務品質、便捷的交通網、以及提供舒適、安全的賣場。而建議個案公司未來適合採行產品擴張策略，以發揮個案公司的核心能力，並能繼續累積未來的競爭武器。 本研究對其他中型百貨公司業者的建議為中型百貨業者必須採取檢討自己優劣勢，採取差異化集中路線，建立自己特色，吸引特定目標族群顧客，以建立顧客忠誠度，才能有生存空間。 對後續研究者的建議為可同時研究多家中型百貨業者，以作出對中型百貨業者更一般化的歸納原則。以及研究大型及中型百貨公司的環境與策略的配適度作一比較，以確定環境策略配適度較佳公司是否績效較佳，並了解是否大型百貨公司的環境策略配適度較中型百貨業者為佳。
