Investigation of factors that affect economic growth has been always attractive. Foreign direct investment is one of the variables that have potential effects on growth. This study carried out to investigate the impact of foreign direct investment on economic growth. We consider the role of natural resources using panel threshold regression model for 1996 to 2015 period and also emphasis on relationship between foreign direct investment and economic growth in Iran by Markov Switching Approach for 1976-2015. Panel threshold regression model formed based on Hansen’s (1999) suggested model then that estimated by Wang’s (2015) proposed method for fixed effect models. Results of threshold regression model showed that natural resources, domestic capital formation, population growth rate and governance indicator has statistically significant effect on economic growth. Threshold level for natural resources is 28.58 percentages. Foreign direct investment variable has different effect on economic growth in regimes. In first regime foreign direct investment increase economic growth but in second regime, that natural resources is more than threshold level, it decrease growth rate. Results of tow regimes Auto-Regressive Markov Switching model for Iran showed that foreign direct investment in recession regime is insignificant but this variable in boom regime has statistically significant effect and this relationship is negative.

The water shortage in most countries has caused farmers to use modern methods instead of traditional irrigation methods, have greater control over water consumption. Among the programs implemented in order to reduce water consumption and increase its productivity in the agricultural sector, is the use of pressurized irrigation method. This study aimed to determine the factors affecting the adoption and development of pressurized irrigation in Ardabil province, the required collected data in the form of questionnaires from farmers for crop year 2015-2016 and using logit regression model. The results indicate that the labor costs of water, literacy, education, income, Second career farmers, cultivation, satisfaction with administrative, expertise and credibility services, have positive effectiveness, and history of agricultural activity, product number, cost of water consumption implementation of irrigation systems, and new irrigation cultivation have negative effect on the acceptance and development of pressurized irrigation cultivation. The average marginal effect factors on the development of pressurized irrigation is 0. 345 The ultimate effect of education, water consumption volume and satisfaction with banking and administrative services on pressurized irrigation development is estimated more than other factors.
