This study employed four research constructs to build up several relationships. The major objectives of this study are to examine the influence relationships among technological opportunity, knowledge spillover, innovative effort, and new product performance and to identify the differences of firm characteristics on various factors. However, a total of 173 of the returned questionnaires were usable. The effective rate of questionnaire is 34.60%. The empirical data was analyzed by descriptive statistics, factor analysis, reliability test, validity analysis, analysis of variance (ANOVA), and then used multiple regression analysis to test the hypotheses.
The major findings of this study are shown as following:
1. The technological opportunity has significant positive influence on innovative effort.
2. The knowledge spillover has significant positive influence on innovative effort.
3. The innovative effort has significant positive influence on new product performance.
4. The technological opportunity has significant positive influence on new product performance.
5. The knowledge spillover has significant positive influence on new product performance.
