Business Unit Strategy and Changes in the Product R&D Budget
利用PIMS数据库样本，分析业务单元的竞争策略和在公司投资组合中的角色如何影响其产品研发投入变化，发现成长型业务的研发决策受竞争和内部资源流动影响，而成熟业务则呈现稳定模式。
This study of changes in Product R&D intensity in business units supplements past studies by including two major classes of independent variables which have not been examined previously: the competitive strategy of the business and role of the business in the overall corporate portfolio. Multiple regression analysis is used on a sample drawn from the PIMS data base. The results suggest that R&D decisions in growth businesses are responsive to competition, evolving strategies, and intra-firm resource flows. In mature businesses, a pattern of stability and R&D equilibrium is evident, even in the face of changes by competitors. Managerial implications are noted.
