The Driving Forces of Economic Growth Before and After the 2008 Global Financial Crisis

This paper investigates the determinants of economic growth in two different periods, 2002-2008 and 2008-2013. As national output can be determined by the functions of production and consumption, the explanatory variables consist of growth rates of investment, labor, household consumption, government spending and exports. Analyzing the data of 129 countries, this paper has four main findings: (i) Investment and exports have positive impacts on economic growth; (ii) Labor has significant positive impact if we investigate the period from 2002 to 2013 as a whole. The effect is only positive in the first period with low statistically significance while remains unclear in the second period; (iii) Household consumption has ambiguous impact on economic growth. There exists some evidences (with 90% confidence level) that household consumption might produce a minor adverse effect on economic growth; (iv) The relationship between economic growth and government spending is positive in the first period and negative in the second.

Insights into rising environmental concern: prompt corporate social responsibility to mediate green marketing perspective

Green investment is a trending marketing strategy that has been endorsed as a prominent financial actor due to the growing environmental issues and business sustainability. With the introduction of green and climate bonds in the last decade, the investment in eco-friendly projects has been deemed a paradigm shift. China has been a pioneer in introducing green and climate bonds, setting a precedent for green investment in the global market. Following the green strategy, therefore, the main aim of this study is to examine the importance of green investment and green marketing for enhancing business performance. Besides, this study has also examined the critical mediating role of CSR. Data were collected from 619 respondents from Chinese manufacturing companies via questionnaires. This study employed the structural equation modeling (SEM) technique to test hypotheses in Smart PLS software. This study revealed that green marketing strategy and green investment positively complement the CSR of companies and their business performance. Moreover, results also showed that CSR plays a significant mediating rolein enhancing business performance positively by stimulating the targeted relationships. With the ascendency of being environment friendly, this study will also be a powerful magnet for practitioners and policymakers

Achieving green environment targets in the world’s top 10 emitter countries: the role of green innovations and renewable electricity production

The rapid pace of industrialisation and economic development in recent decades is not without its environmental consequences. Electricity production, though an important determinant of economic development, remained under studied in the existing literature and only a few models on the electricity productionenvironmental degradation nexus are available. As a first attempt, this study examines the impact of renewable and non-renewable electricity generation and eco-innovations on CO2 emissions in the world’s top emitting countries under the umbrella of the Environmental Kuznets Curve (E.K.C.) Hypothesis. Second-generation panel data techniques, i.e., C.I.P.S. and Bai and Carrion-ISilvestre (2009) unit root tests, Westerlund and Edgerton (2008) and Banerjee and Carrion-i-Silvestre (2017) cointegration techniques and Cross-Sectionally Augmented Distributed Lag Model for short and long run coefficient estimations have been employed in the study. It is found that renewable electricity production and eco-innovations have negative effects, whereas non-renewable electricity production has positive effect on CO2 emission. Moreover, the estimation demonstrated the E.K.C. validation in these countries. It is recommended that fossil fuel dependency in the electricity sector should be reduced by devising policies directed towards green electricity measures. More investment in green innovations to achieve green environment and sustainable growth is also recommended by the study

The dynamic role of ecological innovation and sustainable finance in improving green productivity: evidence from China

This study investigates the influence of ecological innovations and sustainable financing in promoting the Chinese economy’s green total factor productivity (GTFP) from Q1-2004 to Q4-2018. Initially, this study measures GTFP using Data Envelopment Analysis and applies Bootstrap Auto-regressive Distributed Lagged (BARDL) model for dynamic effects. The preliminary results confirm the existence of unit root and a long-term cointegrating relationship among the model variables. The long-run results demonstrate that ecological innovations and sustainable financing have promoted GTFP in China. Moreover, government intervention is imperative to support green productivity growth at the macro level. However, there is a need to control the adverse effect of unemployment in impeding GTFP. Notably, the long-run results reflect the more substantial impact of the stated variables compared to the short run with the convergence towards long-run equilibrium. The policymakers are suggested to prioritise the development of the financial market and technological innovations

Does eco-innovation and green investment limit the CO2 emissions in China?

The continuous upsurge in worldwide economic development and human activities has intensified CO2 emissions that highlighted the significant role of eco-innovation and green investment in curbing CO2 emissions. The study aims to explore the impact of eco-innovation and green investment on CO2 emissions by using the China dataset for time period 1990–2019. The study adopts the ARDL approach. The study used two proxies to determine the impact of eco-innovation, namely environment-related technologies and patents. The empirical estimates of the ARDL approach confirm the negative impact of eco-innovation and green investment on CO2 emissions confirming that these determinants result in limiting CO2 emissions in China. Based on these findings, the study suggests strengthening environmentally friendly policies and the advancement of green investment to mitigate CO2 emissions

Controlling environmental pollution: dynamic role of fiscal decentralization in CO2 emission in Asian economies

The “environment” has become one of the important and debatable topics of the world and policymakers identifying the new predictors of CO2 emissions. Therefore, some economies have been promoting fiscal decentralization to encourage environmental quality by granting more financial autonomy to provincial and sub-national governments. Therefore, this study evaluates the dynamic effect of fiscal decentralization on CO2 in selected nine Asian economies using a fresh dynamic panel ARDL model from 1984 to 2017. The empirical findings show that fiscal decentralization has asymmetric effects on CO2 emissions because a positive change in revenue and expenditure decentralization reduced CO2 emissions in Asia. Moreover, a negative change in expenditure decentralization has also enhanced CO2 emissions in the long run. Thus, clean environmental policies and recommendations can be revised and proposed based on nonlinear findings in the modern era
