The uneven distribution of resources across regions in South Korea functions as a crucial mechanism mediating the intergenerational reproduction of income inequality, extending beyond a simple geographical phenomenon. Income inequality not only raises concerns from a justice perspective but also causes various socio-economic problems including economic inefficiency, hindered talent development, and weakened social cohesion. Particularly, its interaction with other forms of inequality reduces social mobility and solidifies social stratification, making its resolution urgent. While the highest social strata reside in regions with quality opportunities, strengthening their advantages and passing them to future generations, disadvantaged groups remain in areas with poor services and opportunities, unable to obtain chances for upward mobility. Although South Korea has continuously implemented balanced development policies to address this issue, their effectiveness has been questioned. Recently, the need for more effective balanced development policies suited to an increasingly pluralistic society has emerged. This study aims to provide relevant implications for balanced development policies by examining the relationship between regional opportunity structure disparities and income inequality reproduction across major life stages of youth: the growth period including high school and earlier periods, and the university period.
This study begins with the perspective that spatial inequality should be analyzed not only in terms of disparities at specific points in time but also in terms of the comprehensive and cumulative effects that these disparities have on life outcomes. While regional differences at single time points are important in themselves, overlooking the cumulative effects throughout an individual's life course makes it impossible to properly understand the substantial impact of spatial inequality. This study is based on the 'Geography of Opportunity' theory, which enables a cumulative understanding of the relationship between regions where individuals stayed at specific times and their subsequent life outcomes from a life course perspective. It also allows viewing individuals not as passive recipients of environmental influence but as active agents who utilize opportunity structures based on their characteristics and capabilities. Moving beyond existing studies that primarily address direct relationships between regional disparities and outcomes, the absoluteness of opportunities, and unidirectional relationships between environment and individuals, this study distinguishes itself by examining the cumulative effects of disparities at specific time points, the relativity of opportunities, and individual agency within environments.
To achieve the research objectives, this study employed the perspective of regional movement toward opportunities across life stages. If groups that migrated to certain regions at specific times show improved life outcomes compared to non-movement groups, and if movement toward opportunities and utilization of regional opportunity structures occur differentially based on parental background, this indicates that regions mediate the reproduction of inequality. Moreover, if parental background and regional influence are significant at specific time points, those periods represent major times when inequality intensifies in South Korea. The specific analytical approach was as follows: opportunity regions were established based on the distribution of regional opportunity structures. Path analysis models were constructed to examine how regional movement at different life stages affects subsequent changes in individual characteristics represented by 'regional opportunity structure perception' and 'future success expectations and self-perceptions' and how these influence future wage income through life stages. Qualitative interpretation was added to these analytical results to achieve in-depth understanding of the phenomena.
By synthesizing discussions on 'opportunity structures' that condition 'opportunities' affecting individual life outcomes, this study derived regional opportunity structures comprising 'economic opportunities, social relationships, and institutions and services.' Based on this framework, examination of regional opportunity structure distribution revealed disparities centered on Seoul. Seoul holds advantages in terms of the absolute quantity of available opportunity structures as well as qualitative aspects and accessibility. When examining the spatial clustering of opportunity structures, Seoul functions as the central region even within the metropolitan area, which is judged to have significantly more opportunity structures and opportunities than other regions, confirming its position as an opportunity region. Seoul's status as an opportunity region was already firmly established in people's perceptions. Accordingly, this study examined patterns of regional opportunity structure disparities and income inequality reproduction from the perspective of movement to Seoul.
The study utilized survey data collected from 1,014 college-educated wage earners born outside Seoul and interview data collected from 20 of these survey participants.
First, self-reinforcing opportunity structure ecosystems centered on Seoul were confirmed in both the growth period and university period. Seoul solidifies its status as an opportunity region through the circulation and mutual reinforcement of economic opportunities, social relationships, and institutions and services. During the growth period, the concentration of highly educated, high-income parents created a density of private education institutions and social atmosphere, while during the university period, universities and regions mutually influenced each other, simultaneously creating selective concentration of human resources and regional vitality. Transportation services improved accessibility between individuals and opportunity structures in both periods.
Second, improvements in opportunity structures through regional movement to Seoul demonstrated cumulative effects throughout the life course through path dependency in central areas. While the effects of improved opportunity structures on individual characteristics varied by type of opportunity structure, growth period movement to Seoul led to enrollment in Seoul universities, and university period migration to Seoul led to employment in Seoul, creating chain effects that ultimately enhanced wage income. By empirically demonstrating the sustained influence of disparities at specific time points on the entire life course, this study solidified the validity of geography of opportunity theory. These phenomena were observed even after controlling for individual academic capabilities through college entrance exam scores during the university period, confirming the clear existence of regional effects.
Third, this study discovered that parental generations can reproduce income inequality through regional mediation and identified the pathways enabling this process. There were differences in specific patterns between the growth period and university period. During the growth period, entry into opportunity regions was not found to occur differentially based on parental income. However, this is because various factors including occupational factors influence entry into opportunity regions. Parental generations sought to transfer wealth from parents to children by utilizing opportunities differentially in various ways beyond direct entry into opportunity regions. Specifically, they attempted movement to adjacent regions with superior opportunity structures, or enhanced access to quality opportunities through information and financial resources. While utilization patterns differed according to regional opportunity structure characteristics, differential utilization of private education-related opportunities was specifically confirmed as parental generations' differential opportunity utilization aimed at entry into good universities. During the university period, parental background influenced entry into opportunity regions. Parents helped meet conditions necessary for entry into opportunity regions through academic capability enhancement and enabled life in opportunity regions by providing financial support. However, when parental generations with relatively limited information failed to recognize the advantages of movement to Seoul during the university period, this sometimes led to opportunity constraints for their children.
The implications of this study are as follows. First, differentiated approaches by life stage are needed for regional disparities. Efforts to create similar opportunity accessibility within environments are needed alongside creating similar environments. Second, efforts should be made to resolve the existing bottleneck phenomenon centered on universities in Seoul. This requires realistic university evaluation criteria for university selection and efforts to revitalize regional universities. Third, strategies to enable quality jobs to exist in various regions and expansion of social perspectives on quality jobs are needed to resolve quality job disparities that cause gaps and inequality across all life stages. Fourth, when seeking to improve life outcomes through increased opportunity structures, the relativity and complexity of opportunity structures must be considered. Recognition that opportunity structures do not operate independently but work complexly and are relative concepts depending on individuals should be reflected in opportunity structure expansion policies. Finally, resolving regional disparities requires policy design from long-term and cumulative perspectives rather than focusing on short-term results.
