The main purpose of this study is to identify the characteristics of internal environment to enhance corporate entrepreneurship (CE). We used a sample size of 39 firms all over India. We identified 500 firms practicing CE on the basis of number of products, markets, and services and compared their characteristics of internal environment with the CE outcomes. In order to measure the CE outcomes, we adopted the model of Hornsby et al (2002), Kuratko et al (2005), Zahra (1991), and Sathe (2005). We identified 181 respondents from these firms. This study observed that the role of various dimensions including risk-taking propensity, intelligence generation and dissemination, management support, work discretion, rewards, organization flexible boundaries and time availability are critical success factor for CE success.
