Explorative learning is featured as information acquirement, interactive integration, and experiment;while exploitative learning is featured as knowledge storing and rule application. In sub-study 2, the evolvement of organizational learning pattern at different entrepreneurial stages was investigated. The result showed the core learning activities varied with the entrepreneurial stages evolving.In Study 3, based on the 283 qualified samples from 120 different entrepreneurial enterprises, the relationship between entrepreneurial organizational learning and entrepreneurial performance was tested with the SEM. Entrepreneurial performance was divided into two types of performance: innovation performance and growth performance. The results showed explorative learning has a significant contribution to innovation performance, and influence growth performance via improving innovation performance. But exploitative learning only contributes to growth performance, and has no influence on innovation performance. At the same time, the moderate effect of environment factors was tested using the hierarchical regression analysis and divided group regression analysis. The results showed that environment dynamics and environment heterogeneity had significant moderate effects. When the environment is getting more dynamic, all learning activities are becoming more important to entrepreneurial performance. But the thing was getting complicated with the environment heterogeneity increasing. Some learning activities, such as information acquiring, have more contribution to performance. But the contribution of other learning activities, such as rule application, dropped rapidly.In Study 2, we had verified that March’s exploration-exploitation organizational learning model could be applied to entrepreneurial context. And we had found that the learning strategy was different at different entrepreneurial stage. In Study 4, we designed an entrepreneurial scenario, and with the simulated experiment, we explored the characteristics of each learning strategy, and the dynamic transformation between the two learning strategies during the whole entrepreneurial process. Results indicated that: (1) The two learning strategies had different learning curves. The learning curve of explorative learning was disconnected and instable, but that of exploitative learning was cumulative and stable. (2) During the whole entrepreneurial process,entrepreneurs changed their learning strategies time and again, presenting a "exploration - exploitation - re-exploration - re-exploitation" dynamic process. (3) Some key organizational factors (such as entrepreneurial aspiration level and resource for entrepreneurship) had significant effects on learning process.Finally, the main conclusions of this paper were summarized. The theoretical progresses and practical implications of the present study were discussed, as well as the limitations of this study and the directions for future research
