Abstract

The volatility of stock prices in emerging markets is often influenced by macroeconomic indicators such as inflation and interest rates. This study investigates the effect of the inflation rate and the Bank Indonesia Certificate (SBI) interest rate on the stock prices of publicly listed telecommunication companies in Indonesia during the 2020–2023 period. The telecommunication sector was chosen due to its strategic role during the COVID-19 pandemic and its strong contribution to national economic growth. Using a quantitative research design, secondary data were collected from the Indonesia Stock Exchange (IDX) and Bank Indonesia. The sample consisted of 16 telecommunication companies selected through purposive sampling, yielding 64 firm-year observations. Data were analyzed with multiple linear regression supported by descriptive statistics and classical assumption tests, employing SPSS 27 as the analytical tool. The findings reveal that both inflation and SBI interest rates have a significant positive effect on stock prices, with the coefficient of determination (R²) indicating that 90.1% of the variation in stock prices is explained by these macroeconomic factors. This study contributes to the literature by providing empirical evidence of the sensitivity of the telecommunication sector’s stock prices to monetary indicators in the post-pandemic period. The results offer practical insights for investors in making informed investment decisions and for policymakers in formulating monetary policies that indirectly influence capital market performance.

Abstract

This study aims to examine the effect of Green Intellectual Capital (GIC) on Green Innovation Performance (GIP), with Environmental Knowledge Sharing (EKS) as a mediating variable in food and beverage companies listed on the Indonesia Stock Exchange during the 2022–2024 period. The increasing pressure for sustainability and environmentally friendly practices has encouraged firms to optimize their green knowledge resources to enhance innovation performance. This research adopts a quantitative approach using secondary data collected from annual and sustainability reports. The sample was determined through purposive sampling, resulting in 57 firm-year observations. Data analysis was conducted using Partial Least Squares–Structural Equation Modeling (PLS-SEM). The findings indicate that GIC has a positive and significant effect on both GIP and EKS, suggesting that well-managed green intellectual resources contribute to improved innovation outcomes and facilitate knowledge exchange within organizations. In addition, EKS has a positive and significant effect on GIP and plays a mediating role in the relationship between GIC and GIP. This implies that the effectiveness of GIC in enhancing innovation performance is strengthened through the process of environmental knowledge sharing. This study contributes to the literature by integrating the Resource-Based View (RBV) and Knowledge-Based View (KBV) in explaining the mechanism through which intellectual capital drives green innovation. Practically, the results provide insights for companies to develop structured knowledge-sharing practices and optimize intellectual capital to support sustainable innovation strategies and long-term competitive advantage.
