A Study of Effective Components on Virtual Water Trade Management from the ViewPoints of Experts

Document Type : Research Paper


دانشگاه تربیت مدرس


The purpose of this study is to investigate components affecting the management of virtual water trade from water experts’ viewpoints. A survey research was conducted. This research was a descriptive- corelative research based on structural equation modelling. The data collection tool was questionnaire and statistical population included water experts (N=300). Using Krejcie and Morgan’s (1970) Table, 169 experts were selected using sample random sampling method. To determine the validity of questionnaire, a panel of experts consisting of the Department of agricultural extension and education at tarbiat Modares University was used. Furthermore, in order to assess the reliability of the research tool, cronbach's alpha test was used. The value of cronbach's alpha for different parts of the questionnaire was between 0.70 and 0.90. The results of correlation analysis showed that political, economic, environmental, social-cultural and educational-extension components had significant relationship with the dependent variable. To evaluate the Fitting Model of the latent variables and to test the research hypotheses, the structural equation modelling technique was applied through LISREL8.80 software. The results of confirmatory factor analysis confirmed the reliability and fitness of the latent variables of the research. Structural equation modelling showed that 65 percent of the changes in the distribution of Virtual water trade management were explained through external latenet variables and the indices of fitness of the model were approperiate.
