The aim of this study is to compare and analyze structural characteristics of smart city industry focused on Korea and Spain. Structural characteristics of industries were compared focusing on share, penetration, impact path and network clustering of smart industries. Research data used input-output tables established by Korea and Spain in 1995 and 2015, and industries were reclassified into 8 and 25 industries. The analysis model is the Smart SPIN Model. The key finding as follows: It was analyzed that there are differences in the structure and characteristics of the smart city industry between Korea and Spain. Firstly, It is analyzed that Korea has a larger share and penetration rate of IT manufacturing than Spain. On the other hands, Spain has a higher share and penetration rate in the IT service and knowledge service sectors than Korea. Secondly, Korea had many production paths for the IT service and the knowledge service. On the other hands, Spain included more production paths in the IT manufacturing sector. Thirdly, as a result of network analysis, Korea's smart industry has a characteristic that it is difficult to develop independently because it is dependent on traditional industries. In Spain, most of the smart industries were included in one industrial cluster, and it was analyzed to have an independent form. In conclusion, It was found that Korea has the industrial characteristics of a smart city based on IT manufacturing. Spain has the characteristics of smart city industry based on IT service and knowledge service. The results of this study are expected to provide basic data on the direction of smart city promotion and the establishment of smart city policies in Korea.

problems involved in defining and identifying it. However, data on ownership of business establishments may be useful and one of the best alternatives for this empirical research because of use of limited information about control This study examines the spatial patterns of external control in the Korean manufacturing activities between 1986 and 1992. Using the data on ownership iinkages of multilocational firms between 15 administrative areas, it was possible to construct a matrix of organizational control in terms of the number of establishments. The control matrix was disaggregated by three types of manufacturing industries according to the capital and labor requirements of production processes used in. On the basis of the disaggregated control matrix, a series of measures were calculated for investigating the magnitude and direction of control as well as the external dependency. In the past decades Korean industrialization development has risen at a rapid pace, deepening integration into the world economy, together with the continuing growth of the large industrial firms. The expanded scale of large firms led to a spatial separation of production from control, Increasing branch plants in the nation. But recent important changes have occurred in the spatial organization of production by technological development, increasing international competition, and changing local labor markets. These changes have forced firms to reorganize their production structures, resulting in changes of the organizational structures in certain industries and regions. In this context the empirical analysis revealed the following principal trends. In general term, the geography of corporate control in Korea is marked by a twofold pattern of concentration and dispersion. The dominance of Seoul as a major command and control center has been evident over the period, though its overall share of allexternally controlled establishments has decreased from 88% to 79%. And the substantial amount of external control from Seoul has concentrated to the Kyongki and Southeast regions which are well-developed industrial areas. But Seoul's corporate ownership links tend to streteh across the country to the less-developed regions, most of which have shown a significant increase of external dependency during the period 1986-1992. At the same time, a geographic dispersion of corporate control is taking place as Kyongki province and Pusan are developing as new increasingly important command and control reaions. Though these two resions contain a number of branch plants controlled from other locations, they may be increasingly attractive as a headquarters location with increasing locally owned establishments. The geographical patterns of external control observable in each of three types of manufacturing industries were examined in order to distinguish the changing spatial structures of organizational control with respect to the characteristics of the production processes. Labor intensive manufacturing with unskilled iabor experienced the strongest external pressure from foreign competition and a lack of low cost labor. The high pressure expected not only to disinte-grate the production process but also led to location of production facilities in areas of cheap labor. The linkages of control between Seoul and the less-developed regions have slightly increased, while the external dependency of the industrialized regions might be reduced from the tendency of organizational disintegration. Capita1 intensive manufacturing operates under high entry and exit barriers due to capital intensity. The need to increase scale economies ied to an even stronger economic and spatial oncentration of control. The strong geographical oncentration of control might be influenced by orporate and organizational scale economies rather than by locational advantages. Other sectors experience with respect to branch plants of multilocational firms. The policy implications of the increase of external dependency in less-developed regions may be negative because of the very share of unskilled workers and lack of autonomy in decision making. The strong growth of the national economy and a scarcity of labor in core areas have been important factors in this regional decentralization of industries to less-developed regions. But the rather gloomy prospects of the economic growth in the near future could prevent the further industrialization of less-developed areas. A major rethinking of regional policy would have to take place towards a need for a regional policy actively favoring indigenous establishments.

This study investigated the location conditions, spatial linkage structures, and firm specific problems of small firms of the Greater Cincinnati metropolitan area by sectors and by areal distribution. The major locational advantages were closeness to customers and suppliers followed by accessibility to inter-state highways. These results were supported by spatial linkage structures in which within-region linkages occupied a greater portions of linkage, showing the importance of small firms in the regional economy. The linkage patterns showed distance decay effect with high elasticity. While there were no significant differences of locational conditions and spatial linkage structures of small firms between core and peripheral area, a slight difference was identified among sectors. Chemical related manufacturing firms show different locational conditions and spatial linkage structure with weak within-local linkages. The main locational disadvantages were lack of qualified labor, undesirable neighborhood, heavy tax, and space shortage. Considering the biggest problems such as lack of qualified labor, difficulties in sales/marketing, low accessibility to financial resource, and technological inability, the inter-related cooperative business networks among firms and regional institutions, consulting companies, chamber of commerce, and universities are needed to stimulate regional economic development and survival of small firms.

Urban spatial structure is closely related to the spatial distribution of urban economic activities. The spatial distribution pattern is no more than an aggregated expression of the location and/or relocation behavior of individual firms and establishments. In this respect, it is important to identify and examine the factors that affect the spatial behavior of individual firms for a more comprehensive understanding of urban space. Agglomeration economies are one of the most prominent urban economic phenomena in the modern metropolitan area. Most firms in an urban space seek external economies through the spatial clustering of their activities. Agglomeration economies feature prominently in the analysis of urban economic structure across urban areas. While the agglomeration economies between cities focus at the macro-scale of analysis, such economies within any given city focus more on the micro geographical scale. There have been a number of researches on agglomeration economies, among which there are relatively few approaches based on an intra-urban context. This proper explores the agglomeration economies at the micro scale and tries to reseal the spatial realization of the agglomeration economies within and between sectors. Three sectors are considered in the analysis; manufacturing, retail and service. The model is based on simultaneous equation systems combined with spatially weighted variables and estimated by the KRP estimators.

This paper analyzed the impact of the penetration of EV(electric vehicle) and FCEV(fuel cell electric vehicle) into the automobile industry, using a static CGE approach. There are contrasting view on the economic impact of EV/FCEV penetration: negative economic impact due to shrunken intermediate inputs versus positive impact because of input saving technical progress. Regarding environment, there is no clear consensus whether EV or FCEV will contribute to the reduction of $CO_2$ emissions in Korea. This study attempts to provide an answer to these questions. By giving shocks to the input coefficients of automobile industries and automobile using sectors, as well as to the final demands for energies. we integrated the Bass diffusion model into the CGE framework, The result suggests that the EV penetration has adverse impact on the $CO_2$ emission while the FCEV penetration has positive impact. On the other hand, both EV and FCEV have positive impacts on GDP. When considering automobile manufacturing sectors only, adverse impacts on $CO_2$ are demonstrated both for EV and FCEV. However, since the size of $CO_2$ increase is small, these results does not alter the overall effects.

Globally, cloud service is a core infrastructure that improves industrial productivity and accelerates innovation through convergence and integration with various industries, and it is expected to continuously expand the market size and spread to all industries. In particular, due to the global pandemic caused by COVID-19, the introduction of cloud services was an opportunity to be recognized as a core infrastructure to cope with the untact era. However, it is still at the preliminary stage for market expansion of cloud service in Korea. This paper aims to empirically analyze how cloud services can be accepted by users by each industry through extended Technology Acceptance Model(TAM), and what factors influence the acceptance and avoidance of cloud services to users. For this purpose, the impact and factors on the acceptance intention of cloud services were analyzed through the hypothesis test through the proposed extended technology acceptance model. The industrial sector selected four industrial sectors of education, finance, manufacturing and health care and derived factors by examining the parameters of TAM, key characteristics of the cloud and other factors. As a result of the empirical analysis, differences were found in the factors that influence the intention to accept cloud services for each of the four industry sectors, which means that there is a difference in perception of the introduction or use of cloud services by industry sector. Eventually it is expected that this study will not only help to understand the intention of using cloud services by industry, but also help cloud service providers expand and provide cloud services to each industry.

The purpose of this study is in investigating the tax clients for their relationship with tax preparers and the general levels of characteristics for the taxation objects, and establishing significant relationships of the two major factors-satisfaction factors and characteristics of the clients-on the satisfaction of the clients. The results of this study will provide an important basic data required for rational management of tax clients. A total of 20 sub-hypotheses were used, which can essentially be summarized into the following three major statements. The hypotheses investigation results can be summarized as below. First, as for the characteristic factors of the preparer, the taxation knowledge factor and the client satisfaction factor were found to be in a significant median positive relationship, and the experience factor and the client satisfaction factor were found to be in a relatively less significant relationship. Second, the factor on the relationship with the preparer and the client satisfaction factor were all found to be in a highly significant positive relationship. Third, in order to measure the characteristics of the taxation objects, relationships between potential tax reductions factor, probability of taxable income adjustments factor, and the client satisfaction factor were analyzed, and they were found to have positive relationships of relatively high significance. Fourth, the average for the client satisfaction factor by industry was found to be the highest for the manufacturing industry, followed by wholesalers and retailers. Other sectors showed little deviation from the average of 4.9, but this factor was not statistically significant. Fifth, the average difference examination of the satisfaction levels for the clients with or without experience of taxable income adjustments showed that those without experience of taxable income adjustments had higher satisfaction levels. Sixth, 12 study hypotheses had been proposed in order to investigate the relationship between the client satisfaction factors and the client satisfaction levels according to the characteristics of clients. Among the 12 sub-hypotheses, except for the study hypothesis of investigating the relationship between the tax preparer's taxation knowledge and the client's satisfaction levels according to the experience of taxable income adjustments, 11 study hypotheses were all not adopted.

This study is to present empirical data about the needs for quality security of aggregate by randomly selecting aggregate from 4 major locations including A, B, C, D province in Korea, by investigating its quality status in terms of physical properties and particle distribution based on Korean industrial standards(KS). The test results indicated that wide variance in quality, and some of aggregate samples were far below the standard, still many of them are not satisfying KS standards. In addition, the current aggregate manufacturing process that does not include inspection of particle size distribution by sieving and fineness modulus, can induce a possibility of non-KS aggregate's distribution; this provide that the current status of aggregate quality security of Korea is seriously threatened. Thus, it is important to secure each aggregate's quality level under KS standards.

Under the continuing economic growth without increase in employment, issues regarding the impact of IT investment on demand for labor have been continuously raised. Under the circumstance, this study carried out an empirical analysis on the impact of IT investment on employment with a sample of 498 businesses whose domestic sales for the period of six years from 2003 to 2008 are KRW 100 billion or above. The result of the analysis found that IT investment increases employment in most of the industries except for some of the service sectors. In the manufacturing industry, more IT investment increased employment but decreased the flexibility in demand for labor; therefore, IT investment has a substitutional relationship with low-skilled labor and a complementary relationship with high-skilled labor. In the areas of electricity, gas and construction, employment increased as IT investment increased, with the greatest flexibility in demand for labor. In the service industry, increase in IT investment led to more employment and higher flexibility in producer services only. On the other hand, there was no meaningful relationship found between IT investment and employment in the areas of distribution services and social services.
