Indonesia has two modern industrial parks, on the islands of Bintan and
Batam, that have been jointly developed with Singapore.  Both have been
successful and about 87 companies such as Asia Mitsubishi, Philips, and
Siemens Components have committed to projects totaling $305 million in
incvestments in Batamindo Industrial Park, and another 19 companies,
including Yoshikawa Electronics, are operating in the Bintan Industrial
Estate park with $85 million in committed investments.

The successful parks employ thousands of Indonesian workers, and they
also generate significant amounts of exports.  For example, from Batam,
Indonesia exported more than $1 billion worht of electronic products to the world market in 1996.  In addition, that figure has been growing at a rate of more than 20%.

Although cities in Indonesia were not a new phenomenon, from 1971 to 199 the percentage of the population living in urban areas rose from 17% to nearly 31% nationally.  Most urban growth was in cities of more than 1 million in size.  Jakarta's population, 11.5 million in 1990 was projected to rise to 16.9 million by 2000, which would rank it number eleven as the most largest city in the world.  Although the capital enjoyed a disproportionate amount of the nation's resources, with 30% of all telephones in the country, 25% of all cars, and 30% of all physicians, anthropologist P.D. Milone observed in the mid-1960's that "Jakarta has never been a true 'primate' city in terms of being the only center for economic, political, administrative, higher education, and technical functions" in the way that, for example, Bangkok has been for Thailand.

Surabaya has always been a major import-export center and a major naval station, and Bandung has been a center for transportation, higher education, and industry.  Nontheless, in terms of population growth and as a symbol of the centralization of power in the nation, Jakarta has steadily grown importance.
