The impact of technological innovation, research and development, and energy intensity on carbon dioxide emissions is examined in this study. A panel data econometric analysis of relevant variables extracted from the OECD and World Development Indicators databases for 36 OECD and 5 BRICS countries from 2005 to 2018 reveals that the Kao panel cointegration test revealed all countries, BRICS countries, and OECD countries exhibited cointegrated relationships regarding the selected variables. At this point, the correlation matrix shows that none of the independent variables has a strong correlation coefficient with the dependent variable. We also used two regression methods to evaluate the long-run association between the study's variables; the two-stage least square (2SLS) and panel generalized method of moments (GMM) both provide similar results, indicating that they are robust. According to the findings, technological innovation and R&D have a positive association with CO2 emissions, but energy intensity has a negative relationship with CO2 emissions.

Abstract In the process of urbanization in developing countries, transportation infrastructure will be built and population migration will also occur. Although these actions can promote economic growth, they can also affect CO2 emissions. CO2 emissions will affect the health of residents, thereby changing health expenditures. The interaction of these three aspects is also a hot topic among scholars. The BRICS countries are emerging countries with the highest carbon dioxide emissions in the world. Discovering problems from empirical research is the focus of our research. This paper finds that, in the long-term, with CO2 emissions as the dependent variable and health expenditure and economic growth as the independent variables, there is a cointegration relationship between Brazil and China. In the short-term, there is a causal relationship between India’s CO2 emissions and health spending; other countries only show a one-way relationship between carbon dioxide emissions, medical spending, or economic growth. Our recommendations to the BRICS countries are as follows: (1) The BRICS countries should transform their economic development methods and use low-polluting alternative energy sources; (2) Brazil and India should pay attention to the indirect effects of economic growth and align economic growth policies with health expenditure policies. (3) South Africa should pay more attention to the sustainability of the impact of economic growth policies on health expenditures.JEL Classification: C22, E23, I18, O13,

The Purpose. This research is to investigate the relationship between the variables of technological innovation, research and development costs, economic growth, sales and export of weapons and military costs in Iran for the years 2000 to 2017. Design/Methodology/Approach. In this study, we examine using Autoregressive Distributed Lag (ARDL) method to explore the estimating the impacts of technological innovation, research and development costs, economic growth, sales and export on military costs. Findings/Implications. The results of this study showed that the impact of technological innovation and research and development costs on military costs is negative in short-term and long-term. Although the effect that these two variables have on military spending in the short-term is very close, in long-term the effect that research and development costs have on military spending is far greater and more significant. Also, the impact of economic growth on Iran’s defense economy is much less than the variables of technological innovation and research and development costs. So that this effect will be less in long-term. But, the amount of arms sales and exports in the short-term has a positive effect on defense spending, but in long-term it becomes negative and increase in arms sales and exports can help Iran’s defense economy. Originality. The countries defense economy can always have positive effects on military and civilian research and development, scientific innovation and technological progress, in this condition that the country’s macroeconomics can spend military spending on research and development and support innovation and inventions. Eventually adopt arrangements that use the innovations of the defense industry in the civilian sector, which will lead to economic growth. This is the experience of many developed countries that have been able to use the technological advances and innovations of the military sector in the civilian sectors as well, and to cause the economic progress and development of their country.

Aim of study: To evaluate the effects of conventional tillage (CT) and no tillage (NT) systems on the soil organic carbon (SOC) changes, CO2 emissions and their relation with soil temperature and grain yield in a monoculture of irrigated maize during six years.Area of study: In Zamadueñas experimental field in the Spanish province of Valladolid, from 2011 to 2017.Material and methods: The SOC content was determined by collecting soil samples up to 30 cm in November at two years interval. Short-term CO2 emissions were measured simultaneously with soil temperature using a respiration chamber and a hand-held probe immediately before, after every tillage operation and during the maize cycle.Main results: The SOC stock of the top 30 cm soil layers was 13% greater under NT than CT. Short-term CO2 emissions were significantly higher under CT ranging from 0.8 to 3.4 g CO2 m-2 h-1 immediately after tillage while under NT system, soil CO2 fluxes were low and stable during this study period. During the first 48 h following tillage, cumulative CO2 emissions ranged from 0.6 to 2.4 Mg CO2 ha-1 and from 0.2 to 0.3 Mg CO2 ha-1 under CT and NT systems, respectively. Soil temperature did not show significant correlation with CO2 emissions; however, it depended mostly on the time of measurement.Research highlights: No tillage increased the SOC accumulation in the topsoil layer, reduced CO2 emissions without decreasing maize grain yield and minimized the impact on climate change compared to CT system.

With the increasingly prominent problems of global resource consumption and environmental pollution, industrial green transformation has become one of the requirements of China’s industrial development in the new era. However, there is a lack of research on the impact of technological innovation and technology introduction on the industrial green transformation of resource-based cities. To bridge this gap, this study uses the panel data of 115 resource-based cities in China from 2003 to 2016, and uses the dynamic panel generalized method of moments (GMM) estimation method to study the impact of technological innovation and technology introduction on industrial green transformation of resource-based cities. The results show that technology introduction has a negative effect on the industrial green transformation of resource-based cities, while technological innovation can have a positive effect. Meanwhile, technology introduction has imparted a greater role to technological innovation in promoting this transformation. In addition, the interactive effects between technological innovation and technology introduction have obvious heterogeneity on the industrial green transformation of different types of resource-based cities. Therefore, resource-based cities should continue to increase investment in scientific research, to constantly improve and consolidate their technological innovation ability, optimize foreign investment strategy in technology introduction, and strengthen the digestion and absorption of imported technology, while increasing technological innovation and personnel training.

This study explored the effect of energy consumption and economic growth on CO2 emissions. The relationship between energy consumption, economic growth and CO2 emissions was assessed using regression analysis (the pooled OLS regression and fixed effects methods), Granger causality and panel cointegration tests. Data from 70 countries between 1994–2013 were analysed. The result of the Granger causality tests revealed that the study variables (population, capital stock and economic growth) have a bi-directional causal relationship with CO2 emissions, while energy consumption has a uni-directional relationship. Likewise, the outcome of the cointegration tests established that a long-run relationship exists among the study variables (energy consumption and economic growth) with CO2 emissions. However, the pooled OLS and fixed methods both showed that energy consumption and economic growth have a significant positive impact on CO2 emissions. Hence, this study supports the need for a global transition to a low carbon economy primarily through climate finance, which refers to local, national, or transnational financing, that may be drawn from public, private and alternative sources of financing. This will help foster large-scale investments in clean energy, that are required to significantly reduce CO2 emissions.

The current study illustrated the time variance of turning points in the relationship between carbon emissions and income to resolve heated debate on the different responsibility to climate change with 1950–2010 data of five development diversity countries—three developed countries (Germany, Italy, and Japan) and one developing country (India) and one newly industrialized economy (Taiwan). The article also examines the impact of the crisis on emission. The time-varying patterns in the turning points on environmental Kuznets curves (EKCs) were observed by a rolling regression technique with 1950–2010 data regarding the per capita CO2 emissions caused by fossil fuel combustion and the incomes of the countries. Several empirical findings were revealed from this analysis. Per capita CO2 emissions commonly decreased with varying magnitudes in the five countries over time. The EKC hypothesis regarding the CO2 emissions is affirmed again in this study. The announcement effects associated with the Kyoto Protocol was evidenced. As indicated by the occurring GDP of the turning point, there is a strong reduction trend in the income level of the turning points right before the years of Kyoto Protocol; and this decreasing trend nearly ended as the Kyoto protocol approached its end, except in Germany, where the occurring income of the turning points continued to have a decreasing trend. Although the global financial crisis had its effects in the world, the impacts on carbon dioxide emissions vary across countries.

This article investigates the effect of the customs union between Turkey and the European Union on the balance of trade in Turkey. The framework for analysis is an extended trade gravity model onto which the impact of the customs union is applied. The gravity model of trade is estimated using dynamic panel data which applies the generalized method of moments to a sample of OECD countries. Separate estimates were made for the periods before and after the process of trade liberalization in Turkey—1980–1995 and 1996–2012, respectively—as well as for the full period—1980–2012. The main conclusion is that when the European Union is accounted for as an econometric variable, the empirical results are striking: Turkey’s gains resulting from taking part in the customs union are noteworthy, with significant improvement in the trade balance with European Union countries. However, the trade flows, and specifically imports, have been mainly with OECD countries that are themselves not members of the EU. The model indicates that external common tariffs are responsible for Turkey’s trade growth rather than tariffs abolished in the internal market of the customs union.
