validation of networking approach in environmental policy in iran to decrease environmental pollution by factor analysis method

This study attempts to validate the proposed model for environmental policy in iran to decrease environmental pollution by implementing network approach. this descriptive-analytical and cross-sectional study was carried out by survey approach. the statistical population of the study consisted of experts and policymakers in the field of environment who had environmental planning and policymaking experience at the national and regional level. in this research, structural equation method (sem) was used for analysis. the results presented an acceptable and excellent fitness for indices of tli and cfi (0.93). on the other hand, the obtained results for gfi index indicate the relative fitness for the model (0.86). besides, the obtained results for pnfi and pgfi indices (0.78 and 0.84, respectively) revealed the acceptability of the model. also, the registered value for the rmsea index (0.073) presented the acceptability of the model. finally, the results of the factor analysis revealed that this model has enough fitness and total numbers and parameters are significant which confirm the acceptability and excellent fitness of the model. in sum, based on factor loading, it is clear that three main factors related to the data of the network-based environmental policy system, the intervening conditions with the factor loading of 0.96 were the best predictors. among 17 measured items, the component of national maturity had the highest factor loading, and the element of eleventh government environmental policies had the lowest factor loading.
