Abstract

Portfolio investment is a key indicator of financial market health and an important driver of economic growth in ASEAN through increased liquidity and competitiveness. This study analyzes the effect of credit growth, political stability, governance, and labor on portfolio investment in ASEAN countries. A quantitative design was applied using secondary panel data from seven ASEAN countries from 2017 to 2023. Data were analyzed using the System Generalized Method of Moments (SYS-GMM) to address endogeneity and dynamic panel bias. Results reveal that credit growth significantly enhances financial market liquidity and company performance, while political stability strengthens investor confidence by providing a secure environment. Good governance reduces risk and fosters economic stability, while skilled labor supports investment attractiveness. This study concludes that political stability, healthy credit management, and strong governance are essential for attracting portfolio investment flows in ASEAN. Governments in the ASEAN region must improve governance transparency, provide training programs to improve labor skills, and maintain political stability to create a conducive investment climate.JEL: E22, E51, F66.

Abstract

Objective: Portfolio investment plays an important role in supporting economic growth, especially with the advancement of technology that facilitates access to information and financial transactions. This study analyzes the impact of internet users, fintech, cashless transactions, and e-commerce on portfolio investment in Indonesia. Design/Methods/Approach: This type of research is quantitative research using secondary data sourced from the Central Bureau of Statistics, Financial Services Authority (OJK), Bank Indonesia, and the Indonesian Economic and Financial Statistics. The research objects used in this study include 34 provinces in Indonesia. The data analysis method in this study uses Vector Autoregression (VAR). This analysis method consists of several tests, including the stationary test, optimum lag test, Granger causality test, Impulse Response Function (IRF), and Forecast Error Variance Decomposition (FEVD). Findings: The study results show that the four variables affect portfolio investment with varying significance levels. Internet users increase access to financial markets and investment opportunities. Fintech provides efficient digital financial services, cashless transactions offer convenience in financial management, and e-commerce creates profitable investment opportunities. Originality/Value: Unlike prior research that examined these factors in isolation, our approach provides a comprehensive understanding by integrating four variables of digitalization into a single framework for analyzing how digital transformation shapes investment behavior. Using a Vector Autoregression (VAR) method with provincial-level data from Indonesia, the study offers novel empirical evidence on the dynamic interplay between digitalization and financial markets in an emerging economy. Practical/Policy implication: The findings highlight the importance of expanding digital infrastructure, enhancing financial literacy, and strengthening regulatory frameworks to foster inclusive and secure digital investment ecosystems. Policymakers and monetary authorities can apply these insights to design policies that promote fintech innovation, ensure transaction security, and improve investor protection.

Abstract

This study aims to analyze the relationship between industry, small businesses, job creation, and welfare within an integrated analytical framework. This study uses a quantitative approach using Partial Least Squares Structural Equation Modeling (PLS-SEM) analysis, with primary data obtained from questionnaires distributed to 80 respondents in the industrial area of Gresik Regency, East Java, Indonesia. The results of this study indicate that industry significantly influences welfare, both directly and indirectly through small business development and job creation. In this case, small businesses act as a key mediating variable influencing industry's impact on job opportunities and improved welfare. The novelty of this study lies in the development of an empirical model that simultaneously integrates the roles of industry, small business development, job creation, and welfare within a single analytical framework, using small business and job creation as mediating variables. This research contributes to the development economics literature, particularly on inclusive growth. It provides a policy perspective on the importance of effective integration between industry and small businesses as a strategy for improving public welfare.

Abstract

Research Originality: The Originality lies in integrating governance quality and macroeconomic variables within a unified framework while explicitly modeling corruption as a mediating variable, a focus that remains underexplored in prior studies. Research Objectives: This study examines the role of corruption as a transmission mechanism linking governance and macroeconomic factors to investor protection in ASEAN countries. Research Method: Using panel data from six ASEAN countries over the period 2010–2023, this study applies panel-data-based path analysis with bootstrapping to estimate both direct and indirect effects. Robustness checks are conducted using fixed-effects, random-effects, and System GMM estimators to ensure the consistency of the results. Empirical Results: The findings show that governance significantly enhances investor protection, while portfolio investment and interest rates exhibit varying effects depending on institutional conditions. Importantly, corruption is found to play a significant mediating role, indicating that improvements in governance and macroeconomic performance do not automatically strengthen investor protection without effective corruption control. Implications: This study suggests that policymakers should integrate governance reforms with anti-corruption strategies to improve investor protection. Strengthening institutional quality, transparency, and regulatory enforcement is essential to create a more secure and sustainable investment environment in ASEAN economies.  JEL Classification: D73, G38, F21, E44
