본 연구에서는 네트워크 외부성이 존재하는 시장의 기술채택 과정을 시뮬레이션을 통해서 분석하였다. 네트워크 외부성은 시장의 선택이 경로의존적 특성을 가지게 하며 이로 인해 궁극적 결과를 예측하기 힘들게 만든다. 본 연구의 모형은 잠재적 채택자의 이질성을 조절할 수 있도록 하였고 특히 기존의 채택자가 자신의 선택을 자유롭게 변경하는 것이 가능하도록 하였다. 이와 같은 ‘전환’의 허용과 이질성의 증가는 기술채택 과정을 더욱 복잡하게 만든다. 시뮬레이션을 위해서는 행위자 기반 모형을 사용하였다. 행위자 기반 모형은 동태적인 특성이 중요한 상황에 더욱 적합한 분석방법으로 기존의 분석적 연구방식이 가지는 한계를 극복할 수 있다.

한국 사회적기업의 사회적 성과 결정요인

허원창,손동원 피터드러커 소사이어티 2019 창조와 혁신 Vol.12 No.2

This study examines the crucial factors of determining social performance of social enterprises in Korea. Two competing perspectives are proposed and empirically tested. A main perspective regarding firm’s growth is the resource-based theory contending internal resources and capacities as a main motor producing performance of a firm. External support perspective, the competing one, regards the government’s support as the crucial engine in social economies. Employing data from 193 social firms in Korea, we found that government’s support only significantly increased the number of vulnerable people in Korean social structure, and social services for them as well. On the other hand, the resource-based argument was not confirmed in Korean contexts. Based on the findings, this paper discusses the implications about the policy dependence of Korean social economies, and their sustainability in Korean economic ecosystems. 본 연구는 사회적기업의 본연적 책임인 사회적 목적의 달성을 ’사회적 성과‘라는이름으로 설정하고, 기업역량과 정부지원이라는 두 변수를 중심으로 사회적 성과의 결정요인을 분석하였다. 구체적으로 본 연구는 ’사회적 성과‘를 1) 취약계층의고용 및 임금과 2) 취약계층 사회서비스 수혜자 수로 구분하였고, 이에 영향을 미치는 요인으로 기업의 고유역량인 재무축적분과 기업 외적 요인인 정부보조금으로구분하여 사회적 성과의 결정에 대한 실증적인 답을 도출하였다. 분석결과 사회적기업의 취약계층 고용 및 임금은 정부보조금만이 유의한 결정요인이었으며, 매출· 영업이익 등에서 축적된 기업역량은 오히려 영향이 없었다. 또한 취약계층 사회서비스 수혜자 수 역시 개별기업의 재무역량과 무관하며 오직 정부지원금에만 유의한 영향을 받았다. 본 연구는 실증적 결과를 기반으로 한국경제생태계에서 사회적기업이란 새로운 기업 유형이 진화적 안정을 얻고 지속성을 확보할 수 있을지에 관한 시사점을 토론한다.

본 연구는 최근 정부의 주요 에너지 관련 정책 중 하나인 지능형 전력망 확산 사업 중 스마트그리드 거점지구 프로젝트에 대한 경제성 분석을 위한 시뮬레이션을 수행하였다. 연구의 목적은 거점도시의 구축을 위한 인프라 구성을 제시하고, 이에 따라 변동하는 다양한 이해관계자간 비용과 편익의 상호작용에 초점을 두고 가능한 대안을 탐색하여, 최종적으로 모든 이해관계자의 편익이 골고루 높으며, 도시 전체의 경제성이 높은 인프라 구축 대안을 제시하는 것이다. 본 연구결과는 향후 성공적인 스마트그리드 거점도시 프로젝트 수행을 위한 전략적 방향을 수립하는 데 중요한 기초자료로 활용될 수 있을 것이다. This study undertakes a simulation analysis for evaluating the benefits and costs of smart grid hub project. The purpose of the study is to explore extensively the alternatives for infrastructure configurations and identify the best scenarios that can satisfy all the stakeholder needs. We consider 19 parameters for configurating a smart grid hub city, and take a strategy of exhaustive search to find configurations that meet the two criteria simultaneously: each stakeholder's B/C ratio should be equally distributed and the B/C ratio of the entire city should be maximized. The results offer some meaningful implications for building a successful deployment strategy that can facilitate the diffusion of smart grid technologies.

Dynamics of Technology Adoption in Markets Exhibiting Network Effects

허원창 한국경영정보학회 2010 Asia Pacific Journal of Information Systems Vol.20 No.1

The benefit that a consumer derives from the use of a good often depends on the number of other consumers purchasing the same goods or other compatible items. This property, which is known as network externality, is significant in many IT related industries. Over the past few decades, network externalities have been recognized in the context of physical networks such as the telephone and railroad industries. Today, as many products are provided as a form of system that consists of compatible components, the appreciation of network externality is becoming increasingly important. Network externalities have been extensively studied among economists who have been seeking to explain new phenomena resulting from rapid advancements in ICT (Information and Communication Technology). As a result of these efforts, a new body of theories for ‘New Economy’ has been proposed. The theoretical bottom-line argument of such theories is that technologies subject to network effects exhibit multiple equilibriums and will finally lock into a monopoly with one standard cornering the entire market. They emphasize that such “tippiness” is a typical characteristic in such networked markets, describing that multiple incompatible technologies rarely coexist and that the switch to a single, leading standard occurs suddenly. Moreover, it is argued that this standardization process is path dependent, and the ultimate outcome is unpredictable. With incomplete information about other actors’ preferences, there can be excess inertia, as consumers only moderately favor the change, and hence are themselves insufficiently motivated to start the bandwagon rolling, but would get on it once it did start to roll. This startup problem can prevent the adoption of any standard at all, even if it is preferred by everyone. Conversely, excess momentum is another possible outcome, for example, if a sponsoring firm uses low prices during early periods of diffusion. The aim of this paper is to analyze the dynamics of the adoption process in markets exhibiting network effects by focusing on two factors; switching and agent heterogeneity. Switching is an important factor that should be considered in analyzing the adoption process. An agent’s switching invokes switching by other adopters, which brings about a positive feedback process that can significantly complicate the adoption process. Agent heterogeneity also plays a important role in shaping the early development of the adoption process, which has a significant impact on the later development of the process. The effects of these two factors are analyzed by developing an agent-based simulation model. ABM is a computer-based simulation methodology that can offer many advantages over traditional analytical approaches. The model is designed such that agents have diverse preferences regarding technology and are allowed to switch their previous choice. The simulation results showed that the adoption processes in a market exhibiting networks effects are significantly affected by the distribution of agents and the occurrence of switching. In particular, it is found that both weak heterogeneity and strong network effects cause agents to start to switch early and this plays a role of expediting the emergence of ‘lock-in.’ When network effects are strong, agents are easily affected by changes in early market shares. This causes agents to switch earlier and in turn speeds up the market’s tipping. The same effect is found in the case of highly homogeneous agents. When agents are highly homogeneous, the market starts to tip toward one technology rapidly, and its choice is not always consistent with the populations’ initial inclination. Increased volatility and faster lock-in increase the possibility that the market will reach an unexpected outcome. The primary contribution of this study is the elucidation of the role of parameters characterizing the market in the development of the lock-in process, and identific...

Regional migration is a problem faced by all non-metropolitan areas in Korea, but the extent of migration varies depending on regional economic conditions. This study examines how the extent of youth migration varies depending on the economic conditions of their birthplaces. The results showed that youth migration was more severe in areas suffering from population decline and aging problems. The smaller the economy and the weaker the financial independence of the region, the more severe the youth migration. In particular, commercial, educational, and cultural facilities, except for medical facilities, were not able to curb youth migration. In addition, there was a significant wage gap between those employed in the metropolitan area and those employed in the regions, regardless of their origin. This suggests that non-metropolitan areas are caught in a vicious cycle of regional economic deterioration and youth migration.
