    دیدگاه جدید در حوزه تجارت بین الملل و رشد، بر اهمیت پیچیدگی صادرات  است. هدف مقاله حاضر، شناسایی عوامل موثر بر   پیچیدگی صادرات  رشته فعالیت صنعتی ایران می باشد. داده ها و شاخص های مورد بررسی مبتنی بر   رشته فعالیت صنعتی به  تفکیک کدهای دو رقمی آیسیک طی دوره زمانی 2016-2005 است. برای این منظور، از چهار  متغیر واردات ماشین آلات، تعداد نیروی کار ماهر، نسبت هزینه تحقیق و توسعه  و نرخ تعرفه کالاهای واسطه ای استفاده شده است. تخمین ضرایب  در  چهارچوب داده های تابلویی و با استفاده از روش حداقل مربعات تعمیم یافته (EGLS)و حداقل مربعات کاملا اصلاح شده (FMOLS) انجام گرفته است. نتایج  نشان دهنده معناداری واردات ماشین آلات و  تعداد نیروی کار ماهر  در پیچیدگی صادرات رشته فعالیت صنعتی ایران است. ضمنا رابطه معناداری  سایر متغیرها تایید نشده است. این یافته ها نشان می دهد نوسازی صنایع از طریق تسهیل در واردات  ماشین آلات و استفاده از نیروی کار ماهر منجر به افزایش رشد پیچیدگی صادرات صنایع می شود.

    New international trade perspective emphasizes the role of export complexity on industrial growth. Given this importance, the main purpose of this paper is to identify the factors affecting the complexity of Iranian industrial exports using data and indicators based on the field of industrial activity. This field of activity is divided by ISIC's two-digit codes over the period 2015-2004. In this study, import rate of machinery, number of skilled labor force, R&D cost ratio and intermediate tariff rate were used. The coefficients were estimated using panel data using generalized least squares (EGLS) and fully modified least squares (FMOLS) methods. The results show that the coefficients of estimation of the model coefficients show the significant impact of machinery import rate and human capital on the export complexity of Iran's Industrial. Also, the significant relationship of other variables has not been confirmed. As far as the quality of inputs is concerned, when the tariff rate of intermediate goods is taken into account in the field of industrial activity, there is no significant effect on export complexity. The driving force behind this result is the high share of government-run oil and gas-based exports and very little reliance on imported intermediate goods. These findings show that modernizing industries by facilitating the importation of machinery and the use of skilled labor will increase the complexity of industrial exports. Therefore, the establishment of systematic capability and institutional capacity building for the correct selection and absorption of imported technologies is supported by the creation of infrastructures of industrial access to the latest technology. Finally, serious attention to the issue of education in order to raise the level of awareness of the forces employed by the manufacturing firms in attracting new technologies can provide the grounds for increasing the export Sophistication of Iran's Industrial.

    T he purpose of the current research was to empirically examine the relationship between six independent variables and foreign direct investment (FDI) inflows (dependent variable) to countries in the Middle East and North Africa (MENA) region for the period of 2002-2016. The independent variables studied in this research were foreign exchange systems, good governance, inflation, gross domestic product, market openness, and doing business. To test the research hypotheses, a two-stage least squares (2SLS) regression was used to analyze the imbalanced pooled data for the years 2002-2016. The hypotheses were tested at 95% confidence level and Eviews produced two-tailed probability T statistics.  Based on the results of the analysis, none of the six hypotheses could be rejected. This result show that good governance, gross domestic product, openness and doing business had a positive relationship in spite of inflation by the negative effect on FDI inflows.  As for foreign exchange region, the result showed that countries with fixed exchange rate system attracted more FDI inflows as compared to the countries with the two-tiered system.

    The imbalance between water supply and demand in the country has challenged water resource management, especially in the agricultural sector. The virtual water study approach, as an approach that values the use of water inputs in the production and consumption of various commodities, has been established and discussed for almost two decades. Based on this concept, the issue of virtual water trade has become important, and countries are interested in knowing how much water they export or how much they import in the trade of agricultural and industrial goods. In this regard, the international trade in agricultural products and the displacement of water contained in them, known as virtual water exports, can be one of the solutions for water resources management. In this paper, it has been studied the relationship between the country’s virtual water export and water resources inventory of the country for the period of 2006-2013 using the generalized method of moments (GMM) method. Results showed that virtual water exports had a significant positive relationship with the inventory of water resources, GDP, and population.
