The causative factors of environmental degradation in South Asia

Urbanization, economic growth, and intensity of electricity consumption are the important causative factors of environmental degradation in South Asia. The present study has revealed this while investigating the relationship between the level of CO₂ emissions and important economic variables in the context of five South Asian countries. Panel data are used for this study over the period 1974–2017. Panel co-integration tests and the Panel Autoregressive Distributive Lag (PARDL) model are applied for empirical analysis. Robust results of the analysis indicate that urbanization, Gross Domestic Product (GDP) and the intensity of electricity consumption are contributing factors to carbon emissions. Based on the results of the Dumitrescu Hurlin Panel Causality test, it is concluded that there is a bi-directional causal link between urbanization and CO₂ emissions and unidirectional causal links from GDP to CO₂ emissions, from GDP to urbanization, and from the intensity of electricity consumption to urbanization. This study focuses on planned urbanization, eco-efficient income growth, and sensible use of electricity to control CO₂ emissions in this region. Considering the nature of these developing economies in South Asia, collaborative measures and strategic planning are suggested on a regional basis to address the concerns in the above-mentioned areas that minimize carbon emissions and thereby aid sustainable development in this region.     

Testing the nexus between renewable energy consumption and environmental quality in Nigeria: The role of broad‐based financial development

This study investigates the nexus between renewable energy consumption and environmental quality in Nigeria, accounting for the role of financial development, and re‐examines the validity of the environmental Kuznet curve (EKC) hypothesis for Nigeria covering the period 1990 to 2016. To cover financial development more adequately, the current study uses the broad‐based financial development index constructed by the International Monetary Fund. The study employs second generation econometric approaches of Lee and Strazicich, and Bayer and Hanck combined cointegration tests to check for stationarity and cointegration among the variables, and then applies autoregressive distributed lag (ARDL) and vector error correction model (VECM) Granger causality tests to explore the effect and causal relationship respectively. The results divulge that renewable energy consumption improves environmental quality, while financial development hurts the environment. Further, the results validate an inverted U‐shaped association between economic growth and environmental degradation in Nigeria. The VECM Granger causality results indicate a long‐run effect of the independent variables on CO₂ emission, while the short‐run causality reveals a mixture of unidirectional and bidirectional causality among the variables. This study therefore recommends that policy makers consider the important roles of renewable energy and financial development in reforming energy policies to achieve environmental sustainability.     

Regional variation of energy-related industrial CO2 emissions mitigation in China

This paper analyzes the reasons for regional variations in industrial CO₂ emissions mitigation. First, regional industrial CO₂ emissions during the “11th Five-Year Plan” period are calculated based on the presented method. Then a two-level perfect decomposition method, LMDI, is used to find the nature of the factors that influence the changes in energy-related industrial CO₂ emissions in nine economic regions in China. The changes of industrial CO₂ emissions are decomposed into energy emission factor effect, energy structure effect, energy intensity effect, industrial structure effect and economic output effect. As the results suggest, rapid growth of industry is the most important factor responsible for the increase in CO₂ emissions. The adjustment of both industrial structure and energy structure contributes to the increase of CO₂ emissions slightly. Energy consumption per unit GDP is the most important measure of CO₂ emissions and the energy emission factor by itself also makes a weeny contribution to CO₂ reduction as a result of electricity generation efficiency enhancement.     

Electricity consumption and economic development in Asia: new data and new methods

This study uses a new statistical technique, Panel Analysis of Nonstationarity in Idiosyncratic and Common Components (PANIC) analysis, to examine causal linkages between electricity consumption and economic development in 12 Asian countries over the period 1971–2011. The findings indicate that there was no long‐run equilibrium relationship between electricity consumption and economic development in the region as a whole. More importantly, the causality tests detected unidirectional causality from economic development to electricity consumption for East Asian countries and a reverse causal relationship for South Asian countries. These findings have important policy implications for sustainable energy consumption.     

能源消费，经济增长和碳排放：中国面临的挑战

对中国经济增长、CO2排放和能源消费的长期Granger因果关系检验的结果是:CO2排放是能源消费的Granger原因,反向的Granger因果关系则不成立。收入和CO2排放之间没有长期因果关系,这意味着中国不必以牺牲经济增长为代价来减少CO2排放。     

Economic development and carbon dioxide emissions in China: Provincial panel data analysis

This paper investigates the driving forces, emission trends and reduction potential of China's carbon dioxide (CO₂) emissions based on a provincial panel data set covering the years 1995 to 2009. A series of static and dynamic panel data models are estimated, and then an optimal forecasting model selected by out-of-sample criteria is used to forecast the emission trend and reduction potential up to 2020. The estimation results show that economic development, technology progress and industry structure are the most important factors affecting China's CO₂ emissions, while the impacts of energy consumption structure, trade openness and urbanization level are negligible. The inverted U-shaped relationship between per capita CO₂ emissions and economic development level is not strongly supported by the estimation results. The impact of capital adjustment speed is significant. Scenario simulations further show that per capita and aggregate CO₂ emissions of China will increase continuously up to 2020 under any of the three scenarios developed in this study, but the reduction potential is large.     

Accelerating growth in Poland through privatization

Abstract

This study examines relationships among information communications technology (ICT), carbon dioxide (CO₂) emissions and economic growth. The panel annual data are constructed from 1991 to 2009 for nine members from the Association of Southeast Asian Nations. The study examines the long-run equilibrium relationship using cointegration techniques and the short-run relationships using cointegrating regression estimation methods. Test results indicate a long-run equilibrium relationship exists among these variables. Among these relationships, ICT shows significant to highly significant positive effects on both economic growth and CO₂ emissions. Significant to highly significant inverse bidirectional relationships between economic growth and CO₂ emissions are found in the region. Based on these empirical findings, further policy implications for economic growth, ICT and CO₂ emissions are discussed.     

Causal Relationship between Domestic Savings and Economic Growth: Evidence from Seven African Countries

This paper utilizes cointegration and the vector error‐correction model (VECM) to explore the causal relationship between economic growth and growth rate of domestic savings for Congo, Côte d’Ivoire, Ghana, Kenya, South Africa, and Zambia. Specifically, three analyses were undertaken. First, the time series properties of economic growth and domestic savings were ascertained with the help of the augmented Dickey–Fuller unit root procedure. Second, the long‐run relationship between economic growth and growth rate of domestic savings was examined in the context of the Johansen and Juselius (1990) framework. Finally, a Granger‐causality test was undertaken to determine the direction of causality between economic growth and growth rate of domestic savings. The results indicate one order of integration [I(1)] for each of the series. The results of the cointegration tests suggest that there is a long‐run relationship between economic growth and growth rate of savings. The results from the Granger‐causality tests indicate that contrary to the conventional wisdom, economic growth prima facie causes growth rate of domestic savings for most of the countries under consideration.     

Resource‐led Development: An Illustrative Example from Nigeria

Abstract: Several strategies are open to an economy in its attempt to attain sustainable economic development, depending on its historical background and resource endowment. One such strategy is the resource‐led strategy. Nigeria is very rich in crude oil and has reaped billions of petrodollars. However, the country faces the problem of successfully translating this huge oil wealth into sustainable development. This paper employs the vector error correction technique in examining the long‐run impact of the huge oil wealth accruing to Nigeria on its economic development. Basic indicators such as growth, private consumption, infrastructure (electricity), agriculture and manufacturing output growth rates are examined. The empirical results suggest a significant positive long‐run impact of per capita oil revenue on per capita household consumption and electricity generation while a negative relationship is established for GDP, agriculture and manufacturing. Even for those with a negative relationship at current period, there exist positive relationships at subsequent lags. Thus, oil revenue, if properly managed and invested, could be effectively used to induce oil‐led development for Nigeria provided that the initial inhibitions of corruption, lack of transparency, accountability and fairness in its use and distribution are removed.     

Banking Sector Development and Energy Consumption in Nigeria: Exploring the Causal Relationship and its Implications

This study examines the causal relationship between banking sector development and energy consumption in Nigeria over the period 1971–2013 incorporating crude oil price and indicators of economic performance. An autoregressive distributed lag bounds testing approach to cointegration provides evidence of long‐run relationship among the variables. The long‐run and short‐run estimates suggest that a non‐linear inverted U‐shaped relationship exists between banking sector development and energy consumption in Nigeria, indicating that initially, energy consumption increases as the banking sector develops and then declines as the banking sector matures to generate efficiency in energy consumption. In addition, this study explores the direction of causality between the variables using the Toda–Yamamoto Granger causality test procedure. The results suggest that a unidirectional causality runs from crude oil price to banking sector development, from banking sector development to energy consumption and from energy consumption to economic growth. It may therefore be necessary for policy makers in Nigeria to incorporate banking sector development in the energy and sustainable economic policies.

CO2 Emissions Embodied in China＇s Foreign Trade： An Investigation from the Perspective of Global Vertical Specialization

In light of the growth in vertically specialized in global trade, the present paper uses input output tables from the World Input-Output Database to construct an environmental multi regional input-output model to calculate the CO2 emissions embodied in China＇s international trade during 1995-2009. The advantage of this model lies in its incorporation of the re exported CO2 emissions component embodied in trade and its ability to differentiate domestic sourced CO2 emissions from foreign-sourced CO2 emissions in trade. The results show that carbon emissions embodied in both China＇s exports and imports increased significantly during 1995-2009. One important reason for this is that the re-exported carbon emissions embodied in China＇s imported intermediate inputs increased substantially during this period. Our research reveals that accelerating the transformation of trade pattern and upgrading processing trade should be emphasized in the formulation of policy to prompt CO 2 emissions abatement in China.     

Pollution abatement efforts: a regional analysis of the Chinese industrial sector

Although China has had rapid economic growth, it has borne a more significant economic burden or loss because of environmental pollution. However, the country has addressed this problem with various pollution abatement efforts. Some prior studies analysed the relationship between such efforts and pollution emissions, but did not show how these efforts affect pollution reduction. This study investigates the effects of pollution abatement efforts on industrial SO_X, NO_X and CO₂ emissions in the context of pollution reduction in China by panel data for 29 provinces from 1995 to 2010. The empirical results are as follows. First, emissions have increased rapidly in the 2000s. Second, rapid income growth has led to a greater increase in emissions. Third, pollution abatement would assist improvements in environmental quality. Further, this study reveals that abatement efforts affect emissions through the adoption of pollution removal measures.     

Economic Benefits and Environmental Costs of China's Exports: A Comparison with the USA Based on Network Analysis

This paper decomposes economic benefits (value‐added) and environmental costs (CO₂) of exports according to their sources, and maps the global value network (GVN) and the global emissions network (GEN) for China's exports during 1995–2009 from national, sectoral and national–sectoral perspectives. A comparison is conducted between China and the USA. National GVN and GEN show that shares of value‐added and CO₂ emissions from China in its GVN and GEN both decreased first then increased after 2006, while shares from the USA in its GVN and GEN generally decreased. Sectoral GVN and GEN show that among China's exports, “electrical and optical equipment” and “electricity, gas and water supply” were, respectively, the sectors that obtained the most value‐added and emitted the most CO₂. National–sectoral GVN and GEN for China exhibited reciprocal and disassortative patterns, and in‐strengths and out‐strengths of GVN and GEN for China's exports were mainly captured by several domestic country–sector pairs.     

The Finance–Growth Link in Latin America

This paper analyzes the relationship between financial development and economic growth in Latin America with a Granger causality test and impulse response functions in a panel vector autoregression (VAR) model. With annual observations from a sample of 18 countries from 1962 to 2005, it is shown that while economic growth causes financial development, financial development does not cause economic growth. This finding is robust to different model specifications and different financial indicators. Interestingly, when the sample is divided according to different income levels and institutional quality, there is two‐way causality between financial development and economic growth only for the middle income group and for countries with stronger rule of law and creditor rights. The impulse response functions show that a shock to financial development has a positive impact on economic growth only for these subsamples, but the net effect of financial development on growth is relatively small.     

Strategic implications of the Soviet‐North Korean alliance

Abstract

Globalization is commonly defined as a strict economic path by most previous works, but it is really a fuzzy concept with unrestrained dimensions. While the ideological location of an incumbent political party is a powerful predictor of its policy position, the role of a political party in the globalization-growth nexus has never been fully empirically investigated. By applying Pedroni's panel cointegration technique instead of a time-series or traditional panel data approach, this paper aims to empirically re-examine the co-movement and the causal relationship among economic growth, the overall globalization index, and its three main dimensions—economic, social, as well as political integrations—by using panel data for 23 Organization for Economic Cooperation and Development (OECD) countries for 1970 to 2006. Certainly, the political party variable is taken into account as the advanced test is promoted, and we finally discover that all variables move together in the long run. Based on the results of the panel causality test, though the evidence of short-run causality is very weak, it does show long-run unidirectional causality running from the overall index of globalization, economic globalization, and social globalization to growth. Finally, the critical role of the political party is deeply discussed in relation with our results.     

International trade,FDI (foreign direct investment) and embodied CO2 emissions: A case study of Chinas industrial sectors

This paper calculates CO₂ emissions embodied in China's international trade using an input–output analysis, for the period 2000–2010. Based on industrial panel data, the two-step GMM estimation is used to test the impacts of FDI, trade openness, exports, imports and per capita income on CO₂ emissions. The results suggest that: (1) China's growing trade surplus is one of the important reasons for the rapidly rising CO₂ emissions; (2) large FDI inflows further aggravate China's CO₂ emissions; and (3) the industrial sector's per capita income and CO₂ emission relationship show inverted-U environmental Kuznets curve. Therefore, in order to achieve environmentally sustainable development of the economy, China should make efforts to transform its trade growth mode, adjust foreign investment structure, strengthen energy efficiency and develop a low-carbon economy.     

Stock Market Development and Economic Growth: Evidence from Côte D'Ivoire

Abstract: The present paper investigates the relationship between the development of the Ivorian stock market and the country's economic performance. Stock market development indicators were identified and used to calculate the Ivorian stock market development index. A set of control variables were also identified. The empirical results suggest that gross domestic product and stock market development are cointegrated when the control variables are included in the analysis. That is, there is a long‐run relationship between these variables taken together. Moreover, there is a unidirectional causality running from stock market development to economic growth.     

Interest Rate Liberalization and Economic Growth in Zambia: A Dynamic Linkage

Abstract: This paper examines the dynamic impact of interest rate reforms on economic growth in Zambia—using two models in a stepwise fashion. In the first model, the efficacy of interest rate liberalization is examined by regressing the interest rate on the level of financial deepening. In the second model, the causal relationship between financial depth and economic growth is examined by incorporating savings as an intermittent variable in the bivariate setting, thereby creating a simple trivariate model. Using the cointegration‐based error correction model, the study finds strong support for the positive impact of interest rate liberalization on financial deepening. In addition, the study finds that financial deepening, which results from interest rate liberalization, Granger causes economic growth. The results apply irrespective of whether the causality is estimated in the short run or in the long run. Other results show that: (1) lagged financial depth leads to further financial deepening; (2) savings and economic growth Granger cause each other; and (3) financial development Granger causes savings in the long run.     

Estimation of China＇s Embodied CO2 Emissions during 2000-2009

The problem of CO₂ embodied in international trade has attracted increasing attention in China. To analyze this issue, the present paper directly calculates emission factors for 15 industries in 2002, 2005 and 2007. We then examine a consumption‐based system and a single‐region input–output model to estimate China's embodied emissions during 2000–2009. Our results show that, when a consumption‐based system is adopted, China's emissions are lower than those reported by some international organizations. The rapid growth in China's exports is a key determinant of China's rising total emissions. All countries should strengthen their cooperation in improving their current greenhouse gas inventories. Furthermore, China needs to encourage trade in low‐carbon products and technology.
