Abstract

This study addresses the issue of identifying regional disparity analysis, specifically to provide an overview of the level of development disparity in Nganjuk Regency in relation to welfare levels. By examining the income disparity of the population across regions, we can gain insights into the performance success of the economic development in Nganjuk Regency. This can serve as a foundation for future regional economic development planning. The research method employs descriptive analysis using secondary data from the Central Bureau of Statistics (BPS) of Nganjuk Regency, East Java Province, and Indonesia. The calculations of inter-regional income inequality through the Williamson Index and inter-household income inequality through the Gini Index both conclude that there is a rising trend of income inequality in Nganjuk Regency from 2022 to 2023. This increase in income inequality may be attributed to the economic slowdown in 2023, which impacts both regions and income groups, thus exacerbating disparities between regions and among individuals/households.

Abstract

Purpose – This study synthesizes the contemporary literature on the relationship between digital marketing and marketing performance. It aims to identify the theoretical perspectives, underlying mechanisms, and research gaps explaining how digital marketing contributes to organizational performance. Design/methodology/approach – This study employs a Systematic Literature Review (SLR) following the PRISMA framework. A structured search of the Scopus database covering publications from 2020–2025 identified 81 eligible peer-reviewed journal articles, which were analyzed using narrative synthesis. Findings – The review demonstrates that digital marketing is increasingly viewed as a strategic organizational capability rather than merely a promotional tool. Its contribution to marketing performance is mediated through customer analytics, customer relationship management, organizational learning, innovation capability, data-driven decision-making, and digital transformation. The findings also highlight Resource-Based View (RBV) and innovation capability as dominant theoretical perspectives, while revealing inconsistencies in marketing performance measurement and limited theoretical integration. Originality/Value – This study integrates fragmented evidence into a comprehensive conceptual framework linking digital marketing, organizational capabilities, innovation capability, and marketing performance. It clarifies the mechanisms underlying this relationship, identifies key research gaps, and provides directions for future empirical research and managerial practice.
