This paper identifies the mediating role of innovation and moderating role of size of enterprise on the relationship between entrepreneurial orientation and performance of Micro and Small Enterprises (MSEs). For the purpose of this study, the necessary data is collected from 384 MSE's operating in Punjab province, Pakistan. Initially the data are analyzed using SPSS 22 and then, for the development of structure equation modeling, Smart PLS-3 is used. Two aspects of entrepreneurial orientations; namely risk taking and pro-activeness are analyzed and innovation is considered as mediating variable. The major contribution of the study is to identify any moderating effect of size of the enterprise on the relationship between entrepreneurial orientation, innovation and performance of MSEs. These elements basically show the contribution that is made by the innovation and performance of the MSE's. The results reveal that the size of enterprises moderated the relationship between risk taking and performance, pro-activeness and performance as well as innovation and performance.

Green practices are becoming increasingly important throughout the world. The performance of SMEs is becoming a crucial issue because of increasing awareness of consumers about environmentally friendly products; therefore, enterprises not following green practices may face a significant decline in performance. Therefore, the purpose of the study was to identify the mediating role of green product innovation between green entrepreneurial orientation, green transformational leadership, and the performance of SMEs. To meet the objectives of the study, structural equation modeling was applied to the data collected from 384 manufacturing SMEs operating in Amman, Jordan, using systematic sampling. The findings revealed that the mediating role of green product innovation was insignificant at the 5% level of significance but significant at the 10% level of significance. All other relationships were significant at the 5% level of significance. This study provides theoretical support for investing more resources in green product innovation to gain sustainability.
