Abstract

This study aims to identify economic sectors that serve as base, potential, competitive, and leading sectors in Surabaya City, East Java. As a primary trade gateway for Eastern Indonesia and a regional economic hub, Surabaya's development is reflected in its Gross Regional Domestic Product (GRDP) data. This research employs a descriptive quantitative method using secondary data from the Central Bureau of Statistics (BPS). The analysis utilizes Location Quotient (LQ), Dynamic Location Quotient (DLQ), Shift-Share, and Overlay analysis to draw conclusions. The results identify four leading sectors in Surabaya: Manufacturing Industry; Electricity and Gas Supply; Wholesale and Retail Trade (including Car and Motorcycle Repair); and Accommodation and Food Services. These findings provide strategic insights for policymakers to formulate economic development strategies aimed at enhancing regional economic growth.

Abstract

Understanding price transmission in crude palm oil (CPO) markets is essential for evaluating the distributional impacts of export taxation on domestic producers. This study investigates price transmission between Indonesia’s ICDX and Malaysia’s MDEX CPO markets while assessing the welfare implications of export duty (BK) and export levy (Levy) on domestic prices and smallholder income. The analysis employs 1,438 daily observations (2019–2024), Johansen cointegration, Granger causality, and a 30-period Variance Decomposition to capture long-run policy effects. Three methodological innovations distinguish this study: the use of high-frequency daily data, extended variance decomposition, and the separate identification of BK and Levy as fiscal instruments with distinct transmission mechanisms. The results confirm a long-run equilibrium between ICDX and MDEX, with unidirectional price leadership from MDEX to ICDX. Export duty affects domestic prices through a netback pricing mechanism, whereas the Levy is transmitted backward along the supply chain, reducing farm-gate Fresh Fruit Bunch (FFB) prices received by smallholders. After 30 periods, external price shocks explain 49.13% of domestic price variation, compared with only 4.03% from BK and Levy combined. The Levy contributes 4.01%, substantially exceeding BK (0.024%), highlighting its greater welfare impact and the importance of long-horizon analysis for evaluating export taxation policies.
