Java Contributes 58 Percent to the National Economy

In the third quarter of 2016, Indonesia's spatial economic structure was still dominated by the group of provinces on Java Island, contributing 58.40 percent to the Gross Domestic Product (GDP). This was followed by Sumatra Island at 22.02 percent, Kalimantan Island at 7.72 percent, Sulawesi Island at 6.15 percent, and the remaining 5.71 percent from other islands.

Java Island's dominance in contributing to Indonesia's economic sector remains unchallenged. This indicates an ongoing inter-regional disparity in Indonesia. Previously, development was focused on Java Island, a phenomenon known as "Java-centric". However, the government under President Joko Widodo and Vice President Jusuf Kalla has been striving to equalize infrastructure development, shifting towards an "Indonesia-centric" approach. For example, the Trans-Sumatra toll road project, spanning from Lampung to Aceh, has been underway for two years.
