Early applications of portfolio management balanced resource allocation between business units. In the 1980s and 1990s, companies extended the use of portfolio management into new product selection and R&D resource allocation. Technology-based firms are faced with the never-ending task of creating new source of advantage as their competitive and market environment shifts. Continuous product innovation can provide a key role in strategies of firms competing in these environment, and when firms diversify their technological base are likely to benefit from new technological possibilities. Additionally, the growing competition （especially in highly innovation markets）, technological change, and the rate of imitation are source of economic depreciation or obsolescence for the firm’s technology. This article examines the effects of technological diversity on innovation performance and technology depreciation. Comprehensive secondary data on 138 Taiwanese firms in IT sector was collected to test the hypotheses and the result shows that both innovation performance and technological depreciation were positively related with technological diversity. Moreover, relative R&D intensity positive moderate the effect of technological diversity on technological depreciation, on the other hand, industry competition negatively moderate the effect of technological diversity on innovation performance.
