The researcher anticipates that the results of the study can be used as a basis for future population studies in any other township. The study aims to investigate the transition of population growth and distribution of Minsyong Township from 1905 (Meiji 38 years) to 2009 (Republic of China 98 years), which is devided into Japanese colonial period and period after retrocession.
The results of the study show that the range and reason of becoming slower of population growth are different between Pre- Japanese colonial period and Post- Japanese colonial period. During Pre- Japanese colonial period (1905~1920), the population growth became negative because of earthquake, malaria and infectious diseases. During Post- Japanese colonial period (1921~1943), the population growth became slower mainly because of the climate disasters and the war, but the reduced range of population growth in this period was narrower than the pre-period. In Pre- Japanese colonial period, the rate of population growth of Minsyong Township once became higher than the average of population growth of Taiwan because the North-south railway was open to traffic and Dahlin Sugar Refinery was set up. And the range of population increas in Post- Japanese colonial period was higer than that in pre-period because the epidemic and malaria prevention were achieving marked success.
During Japanese colonial period, affected by the institution of Dahlin Sugar Refinery, the population increase in the eastern hills region was the most obvious; however, over 90% populations were distributed in the western plains region, centered around Taniyau street, the most densely populated area. The villages in the neighborhood also became inhabited districts because they were close to Taniyau street and had sufficient irrigation water.
From 1946 to 1969 after retrocession, the population of each village in Minsyong Township grew because the politics and society were getting stable day by day and the conditions of medical treatment and agricultural production were improved. However, the main reason of population growth was from the high birthrate in Minsyong Township. In addition, the situation of out-migration was also quite obvious. Continuing the same population distribution as in Japanese colonial period, the densely populated areas were still distributed around Minsyong streets and their neighborhood. Because of its development early, superiority over trafficc location and sufficient irrigation water, Minsyong Township was still the most densely populated area even after retrocession.
From 1970 to 2009, the following effects of the institution of industrial parks and the establishment of universities made the population growth of Minsyong Township reach its peak again. The population growth areas centered around industrial districts, and then extended all around. The directions of extension were different in various ages. In 1970s, the focus of population distribution moved to south gradually and the position of Minsyong streets was faced with changes. After retrocession in various ages, the annual mean population growth rate of Minsyong Township was higher than any other township. The superiority of Minsyong Township was quite obvious.
For hundred years, the evolution of population growth in Minsyong Township was affected by the natural increase during Japanese colonial period. However, after retrocession, the situation of population growth fluctuation was led by the social increase. Though the changes in the environment had an effect on the population growth and distribution of Minsyong Township, the local factors such as the destruction of Feng Shui, the tyranny from people in upper position, the type of land ownership, etc., were also the key factors which influenced the population growth and distribution of Minsyong Township.
