This empirical study has examined the impact of Chinese investments, namely infrastructure, energy, services, other investment sectors, and trade openness on the economies of the 25 Asian and North African countries along with the Belt and Road (B&R) Initiative for a period of 2007 to 2016 using the Johansen Fisher Panel Cointegration Test, Panel Dynamic Ordinary Least Squares (PDOLS) model, and the Toda and Yamamoto technique for testing causality. The findings revealed cointegration among the variables and that the impact of Chinese investments on economic growth in the host countries is positive, but it has a weaker effect, to a certain extent, in all sectors of the host countries while trade openness positively impacts the countries. Furthermore, there is evidence of a unidirectional causality between some FDI (foreign direct investment) economies while the investment in services and other sectors does not cause economic growth in the host countries. Based on the results, the paper proposes that the host countries increase the FDI in the sector of infrastructure, energy, and technology to enhance their economies.

This paper asymmetrically analyzes the impact of energy consumption and oil price fluctuations on the economic growth of the MENA net oil-exporting and importing nations from 1990 to 2019 using panel nonlinear autoregressive distributed lag (PNARDL) model developed by (Salisu and Isah, Econ Model 66:258-271, 2017). The findings revealed that for the net-oil exporting countries, the impact of nonrenewable energy on economic growth is nonlinear in both terms, where in the both terms, high consumption of nonrenewable energy is influencing economic growth and its low consumption is limiting it. Furthermore, the impact of renewable energy is linear and it is influencing and limiting economic growth in both terms respectively. Moreover, the impact of oil price fluctuations on economic growth is linear in the long run and nonlinear in the short run, where in the long run, increase in it is not influencing economic growth but in the short run, while its decrease has no effect. For the net-oil importing countries, the impact of nonrenewable energy on economic growth is nonlinear in both terms, where in the long run, high consumption of nonrenewable energy is influencing economic growth but in the short run, it is discouraging it; however, in both terms, low consumption of nonrenewable energy has no effect. In addition, in the long run, the impact of renewable energy is nonlinear but linear in the short run; however, none of its impacts is significant in both terms. Also, the impact of oil price fluctuations on economic growth is linear in both terms and in the both terms, it is influencing economic growth. Nonetheless, for all the variables, the impacts are higher in the net-oil exporting countries. Policy recommendations were provided.
