As an important economic section of high efficiency, tourism has an excellent position in the modern world called Tourism Industry. According to the Iranian tourism attractions, this industry may be considered for moving out of single-product condition and dependency on oil. Therefore, the author intends in this article to show some effective factors on demand of tourism and share of each factor. In this case, 11 tourist provinces in a period of 2005 to 2010 were studied. By linear logarithm function and its estimation in panel data method, it was determined that the traveling costs in destination such as variable of total goods and services used index (SHB) and ratio of price of hotels in that province to the family income of other provinces (NHN), are the most efficient variable in total demands for domestic tourism. In addition, coefficient of variable of total local tourism attractions (TJ) and total tourism and travel agencies (TA) is positive, showing direct relationship of number of domestic passengers and two mentioned variables in that province.

The economic liberalization and strengthening financial markets play a crucial role in economic growth. That is why in economic literature there has always been a great emphasis on promoting a stable and sustainable growth through financial development. In the last few decades, countries with more financial openness and more developed financial markets have experienced higher economic growth. A poor approach to financial markets has caused some people to regard them as simple factors of profit or loss resulted from fluctuations in the prices of financial assets, nonetheless, due to the immensity of the impact of financial sector on economy, nowadays, economic growth is not believed to be achieved without an efficient financial sector. This study aims to investigate the impact of liberalization and financial development on economic growth in OPEC countries during 1980- 2014 using panel data and GMM methods. The results show significant positive impacts of financial openness and development on economic growth for OPEC countries. Also, lagged dependent variable, human capital, inflation rate, trade openness, population growth rate and government expenditures have significant positive effects on economic growth.

Objective: The present study investigates in detail the relationship between good governance variables and renewable energy, as well as the moderating role of good governance, which is obtained from the product of the good governance index and the variable of renewable energy consumption. The dependent variable of ecological footprint (environmental destruction) was studied for a selection of countries with a high level of development, including Iran as a sample size, so that the data required for the study were considered for the years 2000-2022.Methods: The present research method is descriptive-analytical and applied. The statistical population of the research was the countries with high level of human development as well as the country of Iran. The data required for the study was annual time series that were extracted from the databases of the UN World Bank and the International Energy Agency and the World Footprint Network for the years 2000-2022. Statistical analysis of data was done using Eviews 13 software. In the following, the root tests of the data panel, M. Pesaran and Shin, as well as Levin, Lin and Chu were used to investigate the reliability of the variables, and finally, after investigating the reliability of the variables, the econometric method of autoregression with ARDL distribution lags was used.Results: The results of the model estimation indicate that increasing the consumption of renewable energy and improving the good governance index can reduce environmental degradation.
