네트워크 경제 하에서 혁신과 경쟁 전략에 대한 기반 연구
안광준(An Kwang-Jun),신동형(Shin Dong-Hyung) 한국기술혁신학회 2008 기술혁신학회지 Vol.11 No.2
한국이동통신 산업의 2G에서 3G로 진화하는 기술 패러다임과 더불어 발생한 경쟁 양상은 네트워크 기반 산업에서의 혁신과 경쟁 전략에 대한 시사점을 제시해 준다. 사례 분석 결과 한국이동통신 산업은 지배적사업자와 후발사업자가 확연히 구분된 가운데 수확체증 법칙으로 인한 지속적인 시장지배자가 존재하는 형태를 보여주고 있고, 이러한 배경에는 시장의 경쟁적 지위에 따라 네트워크 특징과 구조가 반영된 차별적인 혁신과 경쟁 전략이 내재되어 있었다. 본 연구를 통해 전체 네트워크가 발생된 이동통신 산업 특성으로 인하여 후발사업자가 가져오는 와해성 혁신은 지배적사업자의 점진적 혁신에 의해 실패하고 승자독식 체제가 지속되는 현상을 고찰할 수 있었다. 본 연구는 실증적으로 분석이 어려운 복잡계와 네트워크 효과에 관한 연구 주제에 대한 사례분석을 바탕으로 네트워크 특징과 구조를 적용한 수식(Numerical) 모형을 이용하여 시뮬레이션 분석 기법을 이용한 차후 연구에 대한 이론적 기반을 확립하는데 의의가 있다. The existence of network is indeed the single most important factor that brings about new business phenomena in the new digital economy, especially in the IT industry. Network effect refers to a phenomenon that the increase in size of the network leads to increased network value and user utility. It determines the competitive structure of an industry and the performances of industry competitors (Shapiro and Varian, 1999). The phenomenon of increasing returns and winner-take-all enjoyed by the early winner in the competition can be attributed to the existence of positive feedback which increases the value of network and induces more users into join the network (Arthur, 1996; Shapiro and Varian, 1999; Song and Lee, 2003). This research attempts to shed light on the topic of innovation and competitive strategy of network-based industries. We analyze the case of the Korean mobile communications industry, in which a shift in technological paradigm from 2G to 3G brought new changes to the competitive structure of the industry. The Korean mobile communications industry makes an ideal case for analysis since it is an industry whose value is inherently dependent upon its user network. It is characterized by the typical increasing returns, in which a monopolizing player is enjoying firstmover's network effects. Because of the existence of network in the mobile communications industry, latecomers’ disruptive innovations could not outcompete the incumbent’s sustaining innovations. The contribution of this research lies in laying a groundwork for future studies by introducing a numerical simulation model to analyze the complexity theory and network effect.

창업CEO의 특성이 신생기업의 제휴 형성에 미치는 영향

The purpose of this study is to examine the effects of founder-CEO attributes on the formation of alliance networks in venture startups. Viewing alliance formation as an external resource sourcing mechanism which can help a startup venture overcome the liabilities of newness and smallness, we investigate specific conditions of a founder-CEO under which alliance formation is facilitated. Despite the consensus on the critical role of founder-CEOs, our understanding of how they formulate and implement strategies in startup ventures is limited. Specifically, there is little research on the characteristics of founder-CEOs that may affect the formation of alliances. In this study, we focus on the link between the specific attributes of founder-CEOs of new ventures and the firms’alliance formation: prior experiences and external visibility. We develop our hypotheses on the effects of total tenure at previous jobs and total number of previous workplaces and large firm experience of a founder-CEO on the formation of alliances. We also investigate the effect of media exposure of a founder- CEO, as a proxy for external visibility, since external visibility promotes reliability and information procurement. Previously, the relationship between media exposure of executives, including founder-CEOs and strategic results of firms has rarely been examined. This study provides theoretical and managerial implications in that exploiting individual network and media exposures of a founder-CEO can be an effective strategy to facilitate successful alliance formation.We test four hypotheses using 406 unbalanced panel data from 116 Korean venture firms listed on KOSDAQ during 1998-2004. The primary data source was Data Analysis Retrieval Transfer System (DART) operated by Financial Supervisory Service. Data were supplemented and confirmed from TS2000P Database and KIS-VALUE. Results from negative binomial regressions show that the alliance formation is likely to increase as a founder-CEO has longer work experiences and more previous jobs before he or she establishes the venture. It is also found that media exposure of a founder-CEO is positively associated with the formation of alliance network.These findings have some important implications. First, individual social networks of a founder-CEO which were built before the founder establishes a new venture can be precious assets for the startup in facilitating alliance formation. Also, founder-CEOs can make efforts to be exposed on media as an effective strategy to promote forming alliances.A contribution of this study is to examine some attributes of founder-CEOs which can facilitate the formation of alliances in social network perspective. Empirically, we believe that this is the first attempt to investigate specific attributes of founder-CEOs which can affect the strategic results such as alliance formation. Especially, study on media exposure of founder-CEOs is valuable attempt for both theoretical and empirical point of view. There has been little research to examine relationship between media exposure of executives and strategic results of firms. This study can provide theoretical and managerial implications on using media exposures as an effective way to draw successful alliance formation.
