In selected South Asian countries, the study intends to investigate the relationship between urban population (UP), carbon dioxide (CO₂), trade openness (TO), gross domestic product (GDP), foreign direct investment (FDI), and renewable energy (RE). Fully modified ordinary least square (FMOLS) and dynamic ordinary least square (DOLS) models for estimation were used in the study, which covered yearly data from 1990 to 2019. We used Levin–Lin–Chu, Im–Pesaran–Shin, and Fisher PP tests for the stationarity of the variables. The outcomes of the panel cointegration approach looked at whether there was a long-run equilibrium nexus between selected variables in Pakistan, Bangladesh, India, and Sri Lanka. The FMOLS approach was also used to assess the relationship, and the results suggest that there is a significant and negative nexus between FDI and renewable energy in south Asian nations. The study’s findings reveal a strong and favorable relationship between GDP and renewable energy use. In South Asian nations (Sri Lanka, Pakistan, India, and Bangladesh), the FMOLS and DOLS findings are nearly identical, but the authors used the DOLS model for robustification. According to the findings, policymakers in South Asian economies (Sri Lanka, Pakistan, India, and Bangladesh) should view GDP and FDI as fundamental policy instruments for environmental sustainability. To reduce reliance on hazardous energy sources, the government should also reassure financial sectors to participate in renewable energy.

Market conditions in emerging economies are often reported as less stable and volatile. The business sector, especially Small and Medium Enterprises (SMEs) in emerging economies, face several shortcomings including lack of resources, lack of finance, lack of support and lack of human skills, etc. Hence, they look to international support and resources to survive in a long run in the dynamic markets. This research examines the role of international finance, international technology, international experience and international network in SME firms’ Sustainable Competitive Performance (SCP) in Pakistan. SMEs are a major source of employment and value creation and, therefore, are very relevant to Pakistan economic and social development and improved sustainability. Hypotheses were tested on the data set collected from 304 emerging SMEs. After Structural Equation Modelling (SEM) was applied in Analysis of a Moment Structures (AMOS), the results indicate that international finance, international experience and international network significantly positively contribute to SCP, but international technology is not a significant predictor of SCP. This research recommends top managers and policy makers to give enough attention to the particular international resources and capabilities in order to configure their firm survival in the turbulent market.

For this research, we examined the influence of access to domestic and international financing on sustainability performance with a mediating role of innovative performance and a moderating role of access to government support. Data were collected from 317 small and medium-sized enterprises (SMEs) through structured questionnaires. The results indicated that access to domestic and international financing significantly contributes to sustainability and innovative performances. Accordingly, we found a partial mediating role of innovative performance between access to domestic financing and sustainability performance as well as between access to international financing and sustainability performance. Access to government support significantly moderates the relationship between access to domestic finances and innovative performance as well as between access to international finances and innovative performance. Practitioners and policymakers should encourage national and international financial institutions and banks to facilitate SMEs by lending them funds for innovative activities and sustainability performance. Moreover, the government should support SMEs, so that they can contribute to economic growth and the gross domestic product. The implications from these matters will be further discussed in this paper.
