The purpose of this study is to construct the fit model between manufacturing proactiveness and business strategy. This study first proposes a new business strategy framework which categorizes the business strategy types into preemptive strategy, low cost-follower strategy and differentiated-follower strategy. Then, the fit relationship between manufacturing proactiveness and three kinds of business strategies above is developed to be research hypothesises and examined empirically based on data collected from 113 high tech, manufacturing firms. The study results indicated that firms must adopt their business strategies based on the specific decision concerns that their manufacturing involved proactively in order to improve the performance in new product introduction, net profit and sales growth.
