The influence of regional economic growth on migration may also differ by age and generation age due to individual lifestyle. Therefore, this study analyzes an effects of changes in regional economic growth on migration between regions by age group. The result shows that the increase in the growth rate of the regional economy and job creation increased the net migration rate, regardless of age group. Second, it is found that the growth rate of the regional economy and job creation have a greater effect on the net migration rate for the youth population than for the middle-aged group. Third, it is found that the gap between regions in the level of individual income in the 25 to 29 years old and the level of land price fluctuations in the 40 to 64 years old affect the net migration rate. This implies that regional economic growth is still an important factor in the migration between regions, and has a great influence on the youth population.

인구가 성장한다는 사실과 함께 인구가 지역적으로 이동하는 현상은 사회과학에 있어서 중요한 연구대상이 되어왔다. 전통적으로 인구의 동학적 측면은 사회학의 주된 연구대상이 되어왔으며 근래에는 인구학(demography)이라는 새로운 독립과학의 분과로서 더욱 이 분야에서의 연구의 심도와 폭이 확대되었다. 그러나 인구의 동학적 측면을 인간의 경제형태의 일환으로 관찰할 수 있는 기회와 가능성이 점차적으로 크게 부각되자 전통적인 경제이론을 적용함으로써 이러한 문제를 분석/구명하고자 하는 동향이 나타나게 되었다. 특히 인구의 단기적 지역간 이동이 경제사회의 질적인 변화와 이에 따르는 산업구조간의 노동력 균형의 재조정에 따라 원인되고 있다는 사실은 인구의 동학적 측면에 경제학적 분석이 당연히 이루어져야 한다는 요구를 초래시키기에 이르렀다.

To grasp the migration characteristics of the Busan metropolitan area(BMA), this study analyzed the change of population and households, and the migration at the intra-regional and inter-regional scales. The major findings of the study are as follows: First, the ratio of population and households of the BMA to the whole country has continuously decreased, especially those 25 to 39 years of age greatly decreased. Second, the ratio of intra-regional migration is relatively high, and the ratio of inter-regional migration is relatively low in the BMA compared to the Seoul metropolitan area. Thus, Busan seems to be less integrated with the urban fringe. Third, the out-migration towards the Seoul metropolitan area from Busan has increased, so that Seoul metropolitan area becomes to have more considerable influence upon the population decrease in Busan.

지난 몇 년 동안 전염병 확산을 분석하기 위해 InfluSim 을 기반으로 한 시뮬레이션 모델에 대한 연구가 진행되어 왔다. InfluSim 은 국내 각 지역의 인구 통계학적 특성과 인구 이동 등을 고려하지 않는 한계점이 있다. 이러한 이유로 InfluSim 에 의한 시뮬레이션 결과로부터 전염병 확산에 대한 방역 대책을 마련하는 것은 부적절한 측면이 있다. 이러한 문제점을 극복하기 위해, 우리는 패치 모델을 개발하였다. 패치 모델은 전국을 16 개 권역으로 나누어 각 지역의 인구 통계학적인 특성을 고려하고, 각 지역 간의 인구 이동을 고려한다. 패치 모델은 InfluSim 모델을 기반으로 하고, 16 개 지역의 인구 통계학적 특성 및 지역 간의 인구 이동량을 네트워크 모델로 보완하였다. 본 논문은 패치 모델 기반의 시뮬레이션 시스템에 대해 서술한다.

This paper has focused on the geographical patterns of migrations and the influence of housing value(apartment) per pyung on the migrations within the one city(Seoul) for 1995$\sim$2003. The migration flows which are composed of the origin, the destination and the number of migrants, are examined at the administrative gu and dong level. As most migrations occur among adjacent gus and dongs, short-distance migration is prominent But there is a tendency for the short-distance migrations to occur between specific regions. Since the economic crisis of 1997 out of which Korea was rescued by IMF, differentiation of housing price is so evident that residental relocation is selective among dongs. It seems that the differentiation of housing price has begun to facilitate the relocation of households. Certain social groups are excluded from high-quality residences, as they cannot afford the high price. The number of migrants between dongs is closely related to the variation of the housing value per pyung within dongs. The short-distance migration may reflect this phenomena simultaneously. It seems that the intra-urban migrations in Seoul play a important role to produce and reinforce the residential segregation.

In the studies on residential move, there has been tendency of dichotomy where short distance moves are largely caused by housing to adjust to changes in households while long distance moves are induced by shift in labor market. However, some empirical studies have proven that residential move is so complex process that the simple dichotomy should be elaborated. In this sense, the present study seeks to identify compounded course of residential move in Korea. In determining migration history, families with younger householders, renters, householders with higher educational attainment and smaller households show a higher probability to move. In case of mobility, women were more prone to move compared to man. Women compared to man, older age augmented the probability to own a house after migration. Families with householders following an occupation of sales and technical service showed lowest tendency to own houses while it marked the highest in the group of professionals. Higher land price of a region was negatively related to owning houses after migration. The present study revealed that factors in macro level as well as micro level significantly affect the move of individuals with varying effects in accordance with migration history.

This study analyzes the determinants and patterns of regional migration in Myanmar. Population migration is affected by various factors such as economic and social factors as well as regional characteristics. It is affected by factors such as income, employment and social overhead capital. Therefore, this study attempts to analyze the following two research problems. First, I would like to analyze whether the reform and opening of Myanmar is causing the migration of rural to urban population. Myanmar is also trying to verify the pattern of population migration experienced by other developing countries. Second, we analyze the impact of social overhead capital on population migration in Myanmar. We analyze the impact of basic infrastructure such as roads, electricity and water on population movements. This will give implications for investment policy decision of social overhead capital for balanced regional development. First, the pattern of population migration in Myanmar is shifting from rural to urban areas, as other developing countries have experienced. Myanmar's urban areas of Yangon and Mandalay have been analyzed as having migration. Second, the expansion of social overhead capital was found to have an impact. Social overhead capital such as roads and educational environments were analyzed to have the capacity to inhale the population. Especially, the educational environment of the region has a great effect on population migration. It is analyzed that education reform is an important policy issue for the balanced regional development of Myanmar. Fourth, employment opportunities were analyzed to have the greatest impact on Myanmar population movements. In the early stage of economic development, it is analyzed that the population moves to a region where employment opportunity is high in the situation where foreign capital is coming in. It is analyzed that the direction of inflow of foreign capital and the imbalance of development in the region will be determined in the situation where the economic development is carried out through foreign capital.

The main objective of this study is to conduct subnational population projections of Korea based on a multiregional cohort-component method. This objective is accomplished by: (i) establishing a viable framework to implement the multiregional cohort-component method with reference to the Markov chain model and Rogers' multiregional population projection model; (ii) applying the established framework to subnational population projections of Korea, 2005~2030. The main results are twofold. First, the proposed method turns out to be highly valid in a methodological sense, which is seen from a high level of coincidence between the estimated and the observed. Second, the projection results turn out to be highly useful in the sense that interregional migration flow matrices are resulted for projection periods. The projected migration flows are expected to provide invaluable information for an understanding of future population change and for a formulation of policy alternatives. This study is strongly inspired by the multiregional perspective emphasizing the evolution of multiple regional populations interconnected by interregional migration flows rather than the overall national change.

The main objective of this study is to establish a population projection method based on the biregional cohort-component method and to apply it to population projections for Busan. Some drawbacks of using the net migration cohort-component method in a regional or local level population projection are demonstrated. A biregional cohort-component method, a variant of the interregional cohort-component method, is established as an alternative where in-migration and out-migration are separately considered and then are combined to produce a projection for the migration component. Predicated on the established method, population projections for Busan are undertaken for the period of 2005~2030 under three different scenarios. Considerably different projection results are obtained between the net migration and biregional methods; among others, the trend of population decline is more severe in the former than in the latter. An investigation of the temporal trend of the projected population shows that the proposed method is highly reasonable. In conclusion, the proposed method based on the biregional cohort-component method seems not only to be theoretically more robust than the net migration cohort-component method but also to be very effective in the real world application.

In an era of population decline, depopulated regions facing challenges in attracting inbound population migration must enhance urban vitality through the attraction of living populations. This study focuses on Busan, a city experiencing population decline, comparing the spatiotemporal distribution characteristics of registered residents and living populations in various administrative districts (Eup-Myeon-Dong) using mobile communication big data. Administrative districts are typified based on population change patterns, and regional characteristics are analyzed using indicators related to urban decline and vitality. Spatiotemporal distribution analysis reveals generally similar density patterns between registered residents and living populations; however, a distinctive feature is observed in the city center areas where the density of registered residents is low, while the density of living populations is high. Divergent trends in spatial patterns of change between registered residents and living populations show clusters of registered population decline in low-density areas and clusters of living population decline in high-density areas. Areas adjacent to declining living populations exhibit large clusters of population changes, indicating a spillover effect from high-density to neighboring areas. Typification results reveal that, even in areas with a decline in registered residents, there is active population influx due to commuting or visiting. These areas sustain an increase in the number of businesses, confirming the presence of industrial and economic growth. However, approximately 47% of administrative districts in Busan are experiencing a decline in both registered residents and living populations, indicating ongoing regional decline. Urgent measures are needed for enhancing urban vitality. The study emphasizes the necessity of utilizing living population data as an urban planning indicator, considering the increasing limit distance of urban activities and growing interregional interaction due to advancements in transportation and communication.
