Abstract

The achievement of economic growth is equally important as environmental sustainability. Economic growth is considered capable of enhancing the overall welfare of society. However, there is a sacrifice stemming from economic growth in the form of negative external impacts. Therefore, the objective of this study is to examine the Environmental Kuznets Curve (EKC) hypothesis in Indonesia and India. The EKC hypothesis connects economic growth with CO2 emissions. The Autoregressive Distributed Lag (ARDL) model is employed to assess both the long-term and short-term impacts of economic growth on CO2 emissions in Indonesia and India. Additionally, the study seeks to comprehend the applicability of the Environmental Kuznets Curve (EKC) hypothesis in these countries over the period of 1965-2021. The research findings indicate that economic growth has a significant impact on CO2 emissions in the short term, but this influence is not sustained in the long term in Indonesia. In contrast, in India, economic growth does not exhibit a significant effect on CO2 emissions in the short term, but it does have a notable impact in the long term. This implies that Indonesia does not align with the Environmental Kuznets Curve (EKC) hypothesis in the long term, while India is anticipated to adhere to the EKC hypothesis in the future.

Abstract

Manufacturing companies have adopted information technology to create integrated systems that facilitate coordination within the company and with external partners. This demonstrates the company's ability to generate supply chain resilience to address current global uncertainties. The study obtained data from 112 respondents from manufacturing companies in Indonesia using purposive sampling. The data were processed using PLS with an outer model test, which met the validity and reliability requirements. The results of the research hypothesis testing showed that information technology adoption plays a significant role in improving purchasing strategy, production flexibility, and supply chain responsiveness. Purchasing strategies that segment purchasing categories and involve suppliers in problem-solving can increase production flexibility but do not directly affect supply chain responsiveness. Production flexibility in a company's operations directly impacts supply chain responsiveness and resilience. Purchasing strategy and supply chain responsiveness contribute to supply chain resilience by developing capabilities. Companies can routinely identify risks and recover from disruptions. Practical contributions can provide management insights into building corporate resilience by aligning purchasing strategies, production flexibility, and supply chain responsiveness to optimize information technology for internal and external integration.
