The work investages the long-term migration of industrial/sectoral population of Taiwan over the last three decades. We first estimate the industrial/sectoral drains of prefectural data in terms of the national industrial/sectoral structure of population . In contrasting, we also characterize the prefectural long-term industrial/sectoral development into categories: no the industrial/sectoral transition of population within a city, the single industrial/sectoral transition of population within a city and the multiple industrial/sectoral transition of population within a city. Some implication lying behind the characteristics are discussed.
