大都市에로의 接近性變化가 農業人口構f造에 미치는 影響

Abstract

Since 1970, structural shift from agricultural sector to industrial sector has been resulted in rural-urban migration. This has been the greatest phenomena in Korea along with the economic development during the 1970S. Rural-urban migration and growth of large cities (Seoul, Incheon, Daejeon, Gwangju, Daegu, Busan) changed the national spatial structure. And the construction of highway in this period influenced the change of accessibility between regions.

The purpose of this study is to analyse the impacts of the accessibility to large cities on agricultural land use and population structure. It has been said that depopulation and selective migration changed the agricultural land use patterns and population structure. It seems to be important to clarify the regional difference of these phenomena. The hypotheses in this study are, 1) changes of accessibility to large cities influence the agricultural land use patterns, and 2) difference in land use will cause the changes

of the agricultural labour structure, i. e. age and education structure. Data by Si, Gun (n= 181) in 1970, 1980 are analysed comparatively to clarify the changes of the regional structure on national scale according to the accessibility. Accessibility is calculated by using the time distance from each region to Seoul and large cities. The changes in agricultural land use pattern are explained by the harvested acreage of vinyl and green house. Population structure is explained by the ratio of highly productive population (age 25~39 years and high education attainment) to total population.
