Abstract

This study estimates green efficiency in the manufacturing sector across six provinces on Java Island and identifies benchmarks for environmentally friendly industrial governance. A quantitative descriptive approach was applied using an input-oriented Slack-Based Measure Data Envelopment Analysis (SBM-DEA) model with Variable Returns to Scale (VRS). The study covers Banten, DKI Jakarta, West Java, Central Java, DI Yogyakarta, and East Java during 2018–2022. Inputs include capital, labor, and fossil energy consumption, while outputs consist of industrial GDP (desirable) and CO₂ emissions (undesirable). Secondary data were obtained from Statistics Indonesia (BPS) and the Ministry of Energy and Mineral Resources (ESDM). The results show that Banten, DKI Jakarta, West Java, and DI Yogyakarta consistently achieved full green efficiency (score = 1.0000). In contrast, Central Java (average 0.8556) and East Java (average 0.7034) remained inefficient due to excessive emissions and inefficient energy use. Benchmark analysis indicates that Central Java reached temporary efficiency during the pandemic but declined in 2022. Meanwhile, East Java shifted its efficiency benchmark from DI Yogyakarta to DKI Jakarta and West Java, reflecting a transition toward lower-carbon industrial practices.

Abstract

As sustainability becomes increasingly embedded in global normative frameworks, the persistent technological and informational asymmetries faced by developing countries remain salient. This article examined whether inward foreign direct investment (FDI) facilitates the transmission of environmentally beneficial practices from foreign enterprises to host economies. Previous studies found mixed results; one argues that foreign firms contribute to environmental upgrading, while others contend that foreign firms invest in developing countries primarily to exploit lenient environmental regulations. To address this debate, the analysis applies Autoregressive Distributed Lag (ARDL) techniques to an extensive time series covering the period 1970-2022. The results suggest that, in the long term, FDI can improve environmental quality in Indonesia through reductions in CO₂ emissions. This finding supports the pollution halo hypothesis. In the short term, however, FDI exhibits a negative but insignificant effect, suggesting a gradual transition toward more sustainable operations. Additionally, trade openness and industrialization lead to greater CO₂ emissions, implying that increased trade and industrial activity may elevate the demand for “dirty goods” and consequently diminish environmental quality.
