Revisiting the nexus between migration, energy consumption, innovation, and CO2 emissions in Germany
The study investigates the nexus between innovation, labor migrations, energy consumption and CO2 emissions in Germany for the period 1990–2020. This study applied a dynamic simulated ARDL (DS-ARDL) model for estimation, which can observe the negative and positive variations in variables both in long run and short run. The dependent variable in DS-ARD provides a more intuitive picture of dynamic effects than coefficients alone. In Addition, DS-ARDL may provide reliable estimations even if sample size is smaller. The results of this study suggest a long-term relationship among innovation, migration, energy consumption, and CO2 emissions. The results also confirm that migration has a positive relationship with CO2 emissions, while innovation has an adverse effect on CO2 emissions in long run. Policymakers can take action on both ends of the supply and demand spectrum to lessen the impact of migration on Germany's CO2 emissions. Human capital accumulation provided by international migration; therefore, receiving countries should encourage rapid technological advancement and improve their citizens' spending habits.
期刊介绍：
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
