In this study, correlation analysis (covariance matrix analysis type) and casual-relationship methods were used. Model formulation was based on a random survey of agricultural personnel. Model parameter estimation was supported by structural equation modeling. Analysis unit of this study consisted of all personnel of Karaj city agricultural jihad organization from Iran country. Statistical sample based on the Morgan table, included 80 agricultural personnel from the statistical population of 100. In this study, structured questionnaire applied to gather the required data. For analyzing data, descriptive statistics and zero-order Pearson correlation analysis were used. Moreover, a two-step structural equation modeling (SEM) procedure was employed to establish construct validity and test the relationships of entrepreneurial orientation (EO), entrepreneurial management (EM), entrepreneurial self efficacy (ESE), and job performance (JP) among agricultural personnel. SEM is an a priori technique, meaning that the researcher must specify a model (conceptual framework), in order to conduct the analysis (Kline, 2005). In SEM, parameters are estimated by minimizing the difference between the observed covariances and those implied by the model. In the present study, Lisrel 8.50 package was used to test the relationships of specified constructs in the study framework.
The estimation method employed was maximum likelihood (ML). Generally, self efficacy perception is defined as the belief in one’s ability of implementing entrepreneurial activities in connection with the evaluation of managerial, functional and technical capabilities. The ESE scale developed by De Noble et al. (1999), applied for measuring ESE among agricultural personnel. This scale, measure the six main components (skills) of ESE construct. These dimensions are as follow: 1- Opportunity recognition, 2- Building an innovative environment, 3- Mission and Vision creation, 4- Cope with risky situations, 5- Obtaining funds and 6- Employ and develop human resources. This scale because of positive results of confirmatory factor analysis and its frequent use in the previous research used to measure ESE construct. For example, in the study of De Noble et al. (1999), all components of this construct confirmed by factor analysis. Items of entrepreneurial self efficacy (ESE) were measured on the Five – Point Likert type scale (From 1, very little extent to 5, very large extent). The 6-item scale measuring job performance (e.g., “I am effective in my job.”) used the studies by Ang et al. (2003) and Kim et al. (2009). Antecedents of entrepreneurial Orientation (EO) which included three sub-dimensions (innovativeness, risk taking and proactiveness) and entrepreneurial Management (EM) which included five sub-dimensions (strategic orientation, resource orientation, management structure, reward philosophy, and entrepreneurial culture) respectively were measured with scales of (Covin & Slevin, 1989), and (Brown et al., 2001). Both scales have been used as summed indexes. Items of job performance (JP), entrepreneurial Orientation (EO), and entrepreneurial Management (EM) were measured on the Five – Point Likert type scale (From 1, strongly disagree to 5, strongly agree).
