This study is to structurally examine the regional income disparity in Korea. It measures the regional income inducement by household consumption expenditure per unit income, and the regional interdependency of income using 2005 and 2015 Regional Input-Output Tables of 16 provincial regions of Korea. The results are as follows. Firstly, the income inducement by consumption expenditure per unit income decreased overall, mainly due to the decrease in the income inducement of other regions than due to that of their region. Secondly, in many regions, the inter-relational income dependency per unit income decreased also, this too, mainly due to the decrease in the income transfer to other region. And, the income inducement effects of consumption expenditure per unit income of Seoul and Gyeonggi, which occupy a large portion of the Korean economy, were lower than that of other regions, but took the largest portion of income inducements generated by other regions as well as by themselves and absorbed the income transfers from other regions the most. The higher income inducement and income absorption in Seoul and Gyeonggi by consumption expenditure of other regions were mainly because of the high share in service of their consumption structure, the progress in tertiarization of their industrial structure, and the high wage portion. These results also mean that viewed from the regional interdependency of income, the income of Seoul and that of Gyeonggi are highly dependent on the income of other regions. Especially, Gyeonggi which leads the overseas exports of high-tech based manufactured products, has other external factors that contribute to their high income inducement, whereas, Seoul which shows high income absorption using its inter-relations with other domestic regions based on the services, has an income-generating structure that is sensitive to other regions' economic situation. Amid overall declines in regional income inducements and in income transfers, and continuing concentrations into Seoul and Gyeonggi regions, to alleviate the regional disparity, the regional industry policies should, rather than benchmarking the policies of the two concentrated regions, enhance their own inter-regional relationships by strengthening the comparative advantage of their regionally specialized industry.

This study aims to answer two questions using input-output decomposition analysis: 1) Have emerging Asian economies decoupled? 2) What are the sources of structural changes in gross outputs and value-added of emerging Asian economies related to the first question? The main findings of the study are as follows: First, since 1990, there has been a trend of increasing dependence on exports to extra-regions such as G3 and the ROW, indicating no sign of "decoupling", but rather an increasing integration of emerging Asian countries into global trade. Second, there is a contrasting feature in the sources of structural changes between non-China emerging Asia and China. Dependence of non-China emerging Asia on intra-regional trade has increased in line with strengthening economic integration in East Asia, whereas China has disintegrated from the region. Therefore, it can be said that China has contributed to no sign of decoupling of emerging Asia as a whole.

This study aims to analyze the convergence change of smart city industries in Korea. Industries of Smart city can be defined ICTs and Knowledge embedded construction industry. The input output model and structural path analysis have been done using the input output tables published by Bank of Korea in 1980 and 2014. GDP deflator was applied to the input output tables. 403 industries were reclassified into 27 industries and 8 industries categories: Agriculture and Mining(AM), Non-IT Manufacture(NITM), IT Manufacture(ITM), Energy Supply(EnS), Construction as smart city(C), IT Service(ITS), Knowledge Service(KS), Etc. Service(EtS). The results are as follows; First, the input output coefficient analysis showed that The information and communication service industry(ITS) and the energy supply industry(EnS) have increased input to the construction industry(C). On the other hands, knowledge service industry(KS) and etc. service industries(EtS) decreased. Second, the multiplier analysis revealed that construction industry(C) led by smart city had a great influence on ITS, EnS, ITM and NITM directly and indirectly. Furthermore, The IT industry had the biggest change from 1980 to 2014. Third, the smart city industry has created a new convergence of 117, and it has been leading to segmentation of the structure. Change of convergence has been proceeding mainly in the ITS and EnS, NITM, ITM industries.

This paper proposes and examines the economic impact of infrastructure improvement on the San-En-Nanshin region in the Chubu area of Japan. We develop a single transportation computable general equilibrium (CGE) model for each subregion within the San-En-Nanshin region. The explicit modeling of the transportation infrastructure is defined based on interregional commuting flows and business trips, considering the spatial structure of the San-En-Nanshin economy. A CGE model is integrated with an interregional transportation network model to enhance the framework's potential for understanding the infrastructure's role in regional development. To evaluate the economic impact of transportation improvement, we analyze the interrelationship between travel time savings and regional output and income. The economic impact analysis under the CGE framework reveals how transportation facilities and systems affect firm and household behavior and therefore induce changes in the production and consumption of commodities and transportation services. The proposed theoretical model was tested by using data from the 2005 IO tables of each subregion and the 2006 transport flow dataset issued by the Ministry of Land, Infrastructure, Transport, and Tourism in Japan. As a result, the paper confirms the positive effect of transportation investment on the total output and income of the studied region. Specifically, we found that while economic benefits typically appear in urban areas, rural areas can still potentially benefit from transportation improvement projects.

This study estimated the regional economic effects by development of the logistics complex in Incheon New Port, applying the regional Input-Output tables in Incheon. And thereby, we tried to find some strategic implications on the priority to induce more effective industries for activated operation of the logistics complex in ports. According to the results, development of Incheon New Port will generate 2,579 billion KRWs(2.2 billion USDs) of production and 1,783 KRWs(1.5 billion USDs) of value-added annually. And we expect it to induce 38.8 thousand jobs, which is over the national average on the input-output table. By the business type, port logistics industry will contribute to develop regional economy more than any other ones in Incheon. We suggest business firms in port logistics industry to be induced to the logistics complex in Incheon New Port strategically. Until now, development of the logistics complex in Incheon New Port are planned to be postponed to 2015 when construction of the berth facilities, the access sea routes and the hinterland highways are completed. We suggest to invest more public fund, to induce the private capital, and then, to develop the logistics complex in Incheon New Port earlier in an appropriate scale.

Input-output(I-O) analysis is now widely used to examine the economic impact of tourism. The study aims to demonstrate the impact of agri-tourism development project on local development in terms of income and employment. Based on the I-O transactions tables developed by Bank of Korea (2011), rural tourism related sectoral multipliers were derived with respect to output, income, employment, and value-added tax. The results of the I-O model indicate that in 2011, rural tourism development generated 1,387 billion Won of output impact, 287 billion Won of income impact, 275 billion Won of value-added impact, and 41,127 full-time jobs, respectively throughout direct, indirect, and induced effects. In particular, the restaurant sector had relative higher output and employment multipliers as compared to other industries, whereas they had lower multipliers of income and value-added than any other industries. The findings imply that the restaurant sector was relatively labor-intensive industry, generating high impact of employment effects.

Korea has achieved a remarkable growth by pursuing externally-oriented growth policy since 1960s. That is, we imported raw materials and spare parts, manufactured them into products and exported them, which led to successful economic development. Therefore, our marine business has played an important roles as one of key industries. The development of marine business has contributed to efficient distribution and cost reduction in addition to production of added value and creation of employment creation, which improved external competitive power. In spite of economic importance of marine business, national perception on it is in general low and its developmental conditions are considerably poor. Therefore, this study aims to speculate the effect of Port-related business on regional economy using regional input-output tables.

The recent analyses of carbon emissions embodied in international trade are related with discussions on who is responsible for the carbon emissions causing global warming. Some authors insist that the countries importing carbon-intensive goods should share the responsibility with the suppliers of those goods. In order to determine which countries are net importers of carbon dioxide embodied in traded goods, we need to construct the multi-regional input-output (MRIO) model incorporating national input-output tables and data on bilateral trades. The paper calculates consumption-based as well as production-based inventories by using MRIO model whose global database is GTAP version 8 to get the picture of carbon footprints in international trades of Korea and other regions in the world.

The regional infrastructure industries of Gwangyang City, the subject of this study, are Gwangyang Port and Gwangyang Steel Mill. Therefore, it is necessary to analyze the regional economic ripple effects of the port logistics industry in Gwangyang City. In this study, a multi-stage approach using the RW and the LQ methodology using the national input-output tables in 2015 and 2019 is used to prepare the regional interindustry analysis chart in Gwangyang City, and an exogenous demand induction model that reclassified the port logistics industry was applied. Through this, the purpose of this study was to provide policy implications by figuring out the regional economic ripple effects of the port logistics industry quantitatively in Gwangyang City. As a result of the analysis, the industries with high production inducement effect and forward/backward linkage effect of the port logistics industry in Gwangyang City were analyzed as manufacturing, transportation, land and air logistics sectors. And the industries in which the added value inducement effect and the employment inducement effect were analyzed as an industry related to the service industry. Therefore, it is necessary to prepare support measures to foster the port logistics industry as a way to promote these industries and revitalize the local economy of Gwangyang City. To this end, it is desirable to improve policies and systems for the vitalization of the Gwangyang port maritime cluster and provide various policy support for the port logistics industry in Gwangyang City. This study is meaningful in suggesting policy implications for the regional economy of Gwangyang City based on the results of exogenous analysis of the port logistics industry in small and medium-sized cities. However, It seems that further studies related to this will be needed in the future.

Currently Welfare is emphasized and the trend of SOC investment shows downwards slopping. The pattern of SOC investment also changes focusing on railroad as environmental issues are critical. This study analyzes and compares the effects of sectoral SOC investments based on Input-Output Tables published by BOK (Bank of Korea). The production inducement, value-added inducement, and employment inducement effects of each sector SOC, which consist of road, railroad, port, and airport, are investigated. First, in view production inducement, sectoral SOC investments have stronger economic effects than manufacture sector. The investment of port and road show the highest value-added inducement in construction process. The investment of road records the highest employment inducement in construction and operation process. The empirical ananlysis of regional economic effects, using Regional Input-Output Tables, supports these explanation showing almost same results. As synthesizing these results, the SOC stocks have to be invested consistently for long periods. Especially the road investment is inevitable for employment. Which sector of SOC is invested depends on circumstances. If government emphasizes production inducement, railroad is invested. If focuses on value-added inducement, port.
