Fiscal Decentralization and Regional Financial Independence in Indonesia: A Systematic Literature Review

Selly Swandari, Andriawan Kustiawan, Imelda Veronica Gea, Akbar Lufi Zulfikar
Abstract: This study examines the development of fiscal decentralization and its relationship to regional financial independence in Indonesia through a systematic literature review. The objective is to synthesize empirical and conceptual… ceptual findings published between 2017 and 2026 concerning the determinants, measurement, and consequences of regional financial independence, particularly the role of local own-source revenue (PAD), intergovernmental transfers, and capital expenditure. Using a systematic search of Scopus, Google Scholar, and Garuda databases, 30 relevant articles were screened, selected, and analyzed following defined inclusion and exclusion criteria. The review finds that fiscal decentralization consistently strengthens local revenue mobilization and administrative accountability when accompanied by adequate institutional capacity, transparent governance, and effective management of natural and economic resources. However, the effectiveness of decentralization varies considerably across regions due to disparities in economic potential, human resources, and political commitment. The synthesis further shows that financial independence positively affects the quality of public services and regional economic growth, although the relationship is moderated by expenditure efficiency and governance quality. The novelty of this review lies in its integrative framework linking revenue-side determinants, expenditure behavior, and governance mechanisms within a single analytical narrative, an integration rarely addressed jointly in prior single-country studies. The findings offer practical implications for policymakers designing fiscal transfer formulas and for future researchers seeking to test moderating variables such as digitalization and institutional quality in the fiscal decentralization–financial independence nexus.

Fitri Anjaswuri, Soewarto Hardhienata, Suhendra Suhendra
Abstract: This study aims to construct an integrated constellation model and determine optimal strategies for reinforcing lecturers’ professional commitment at leading private universities in Bogor. Utilizing the POP-SDM (Modeling… ng and Optimization of Management Resources) framework, the research integrates elements of local wisdom and organizational support within a systemic approach to human resource development. The exploratory qualitative phase involved in-depth interviews and focus group discussions to uncover major determinants influencing professional commitment. From the thematic analysis, four principal variables emerged—teamwork, organizational climate, religiosity, and work motivation—which were validated through expert judgment. Quantitative verification was subsequently performed using the Partial Least Squares–Structural Equation Modeling (PLS-SEM) technique to examine both direct and indirect relationships among constructs. The analysis confirmed that all variables exert positive and significant effects on lecturers’ professional commitment, with work motivation being the most dominant factor. To refine improvement priorities, the SITOREM (Scientific Identification Theory for Conducting Operational Research in Educational Management) method was applied, identifying indicators that should be improved, maintained, or further developed. The findings offer empirical and practical insights, including: (1) a validated POP-SDM–based commitment model combining cultural and organizational dimensions; (2) evidence-based strategies to enhance lecturer professionalism; and (3) an optimization framework to guide sustainable lecturer development in higher education institutions.
