AbstractThis study utilizes structural equation modeling (SEM) to explore the positive effects of corporate environmental commitment and green human capital on green product innovation performance via the mediator: green adaptive ability. Green adaptive ability is the capability to comply with uncertain environmental regulations and environmentalism. This study tests the hypotheses in a sample of 136 of Taiwan's manufacturing companies. The findings in this study highlight the importance of corporate environmental commitment and green human capital that are determinants of green adaptive ability to develop green product innovation. The empirical results show corporate environmental commitment positively affects green product innovation performance directly and positively influences it indirectly via green adaptive ability. Green human capital, however, does not affect green product innovation performance directly. Green adaptive ability is a full mediator between green human capital and green product innovation performance but a partial mediator between corporate environmental commitment and green product innovation performance.
