항만 리모델링사업에 따른 주요 편익에는 선박재항비용 및 하역비용 절감효과, 시민들의 친수성 공간 이용편익 등이 있다. 리모델링은 대체항만 개발에 따른 막대한 기회비용을 피할 수 있으며, 항만 공간이 시민들의 휴식 공간이 됨으로써 많은 편익을 낳을 수 있다. 일본은 제도의 투명성, 유사 사업간 평가의 정합성, 그리고 평가수법의 고도화를 위해 끊임없이 노력하고 있다. 투자평가 시 사업주체의 의사결정에 도움이 되도록 사업에 따른 모든 효과와 비용은 가능한 한 화폐 환산이 가능하도록 한다. 한편 친수성 항만 공간 조성에 따른 항만 녹지, 광장, 위락시설, 수변시설 등의 이용자 편익은 여행비용법으로, 한편 해상안전, 수질 저질의 정화에 따른 편익은 가상가치법으로 각각 추계할 것을 권장하고 있다. 보다 나은 투자평가를 위해서는 평가의 객관성과 신뢰성을 높일 수 있도록 평가 시 최저한으로 준수하여야 할 가이드라인을 제시하도록 한다. 평가의 신뢰성을 제고하기 위해 평가 방법이나 기본 원단위의 개발에 힘쓰고, 평가 사례의 축적을 통하여 사례별 평가결과의 상호 비교를 가능하게 함으로써 유사 사업간 평가의 일관성을 높이도록 하여야 할 것이다.

본 연구의 목적은 사물인터넷 서비스의 효용 비용 및 네트워크 외부성 요인이 소비자의 수용의도에 미치는 영향을 분석하는 것을 통해 사물인터넷 서비스에 대한 소비자 경험 및 행태에 대한 이해를 높이고 실무적으로 유용한 시사점을 제공하는 것이다. 사물인터넷 서비스를 인지하고 있는 20대에서 60대까지의 일반 소비자를 대상으로 온라인 설문조사를 통해 328부의 자료를 수집하였고, SPSS 24.0을 이용하여 빈도분석, 상관관계 분석, 요인분석, 위계적 회귀분석을 실시하였다. 연구결과, 다양한 맥락에서의 사물인터넷 서비스에 대한 소비자 경험 수준이 확인되었고, 오락성, 정보성, 인간가치 상실, 적합성, 호환성이 소비자의 사물인터넷 서비스 수용의도에 유의한 영향을 미치는 것으로 나타났다. 본 연구는 적합성과 호환성을 높임으로써 네트워크 외부성 효과를 강화하는 것이 소비자의 사물인터넷 서비스 수용을 촉진하는 데 있어 중요하다는 점을 시사한다. 향후 연구에서는 구체적인 사물인터넷 서비스를 채택하여 본 연구에서 개발한 모형의 타당성을 보다 정교하게 검증하는 것이 필요하다.

사회마케팅은 1960년대 후반에 마케팅 개념의 확장이 필요하다는 주류 마케팅관리학파에 속하는 일부 학자들의 주장이 제기되면서 태동되었다. 이러한 이유로 인하여 사회마케팅 종사자들은 주로 전통적인 마케팅 수단에 의존하여 사회적 문제를 다루는데 응용하여왔다. 그러나 사회마케팅에 관한 지금까지의 연구문헌을 보면 사회마케팅 종사자들이 상업마케팅의 경우와는 매우 상이한 상황이라 할 수 있는 시장실패와 복잡한 교환을 간과하고 있음을 알 수 있다. 따라서 사회마케팅은 이러한 상황에 직면하고 있음을 고려할 때 전통적인 수단만으로는 사회적 문제를 충분히 다룰 수 없다. 이에 따라 본 연구에서는 사회자본이론이 시장실패와 복잡한 교환현상은 물론 행동변화와 사회적 현상도 고려하고 있기 때문에 사회마케팅 종사자들에게 유용한다는 점을 보여주었다. 사회자본이론을 사회마케팅에 원용하면 사회마케팅 종사자들이 유익한 행동변화를 추구하는데 하나의 지침이 될 것이다.

This paper applies the technology-gap trade theory to explaining radical changes in the competitive positions of countries in world machine tool markets over the last three decades. It develops the notion that the innovation gaps in machine tools among countries led to the inter-country differences in the competitive performance in the sector as well as in its user sectors. Since competitive advantage largely depends on a capability to improve, create and apply technology to market competition, a higher innovative performance in one country than another is closely related to a higher innovative performance. A higher innovative performance in machine tools is also associated with a higher competitive performance of the large areas of its user sectors, due to sectoral interdependences and externalities generated by machine tool innovations. The results of empirical investigation through a panel data analysis show that the international gaps in machine tool innovations appeared to have a positive significant relationship with the differences in the export performance of both the machine tool sector and its user sector across countries.

With rapid advancement of IT and Internet technologies, online market is surely becoming a stage of the competition among various forms of platform providers. This study show the significance of the negotiation process in the platform pricing strategy and observe several external/internal factors that might affect the negotiation power of the identities surrounding the platform. Major theories used in this study are the resource-based-view and network theory. Resources resulting in a negotiation power of the content providers and platform providers turn out to be widely scattered in their business areas - from product characteristics to the size of the content provider. End-user (or buyer) group which cannot make a strategic move for the organized development and use of resources is taking advantage of network externalities to support its negotiation power.

Digital convergence which means the convergence of industry areas related to digital technologies is an important phenomenon in business, which will decide the fates of firms in the near future. The only firms which can create synergy effects from digital convergence are expected to be the winners in the fierce competition of digital convergence era. In our analysis, we examine the strategy of an integrated firm which has businesses in two different industry areas which are related to each other. By using a game theoretical model, we show how the integrated firm can win over two single separated firms which have business in only one industry area each by leveraging the two businesses the integrated firm has. In our welfare analysis, we also show that this convergence may be even beneficial to consumers, which seems counter-intuitive to social concerns about anti-competitive behaviors by integrated firms. Additionally, we study comparison between industry convergence and product convergence.

As Shapiro and Varian argue the open approach generates bandwagon effects and facilitates the diffusion of a standard thanks to network externalities. However, the open approach is not linked automatically to economic benefits as suggested by some famous cases as the IBM PC history. On the contrary, the closed approach enables a tight control over a technology and its development, and insures the appropriation of economic benefits. As Shapiro and Varian suggest, a firm can also decide to mix an open approach with tight control over improvement or extentions. Patent pool is to offer fair, reasonable, nondiscriminatory access under a single license to patents that are essential for the use of standards-based or other platform technologies. patent pool offers only one license to everyone, Since each patent is essential, the royalty rate and thus the value is the same whether a licensee uses one or more patents.

Much of work on network externality assumed network effects are dependent on the network size. Therefore, very little consideration is given to the view that marginal benefits from joining the network may not increase with the network size if consumer benefits come from the direct interaction with neighbors, namely local network. In this study, we used the agent-based simulation method to reexamine the effectiveness of the traditional network market strategy under the presence of the local network where two incompatible technologies compete. We found that the strategy of growing an initial customer base is not effective under the presence of the local network. Our study also showed that targeting customers based on their technology Preference is not as effective as targeting customers within the same local network. As a result, the focus of a network market strategy should be directed to taking advantage of the customer network.

An online marketplace, such as eBay, is an example of two-sided markets. In online marketplaces, there are transactions between sellers and buyers and direct competition effects among sellers and among buyers. Previous research on two-sided market has not handle these competition effects and mostly focused on indirect network externalities between sellers and buyers. We analyze the fee structure of an online marketplace considering direct competition effects among sellers and among buyers. We find that when fees for sellers and buyers can be imposed, an auction or fixed-pricing rule can be chosen according to the characteristics of a product traded. But when only fees for sellers can be imposed, an auction can be taken as a trading mechanism solely.

In this study, a substitution model of the evolutionary generations of technological products is presented. The purpose of the model is to examine the demand side mechanisms which generate successive product life cycles along the path of technological improvements. In the model, the nature of substitution processes is summarized dto the demand function which is derived from the consumer's udtility maximization problem. To describe the nature of technological substitution processes, the concept of the vertical differentiation and the consumption externalities are considered in the utility function. The former is used to characterize the result of technological improvement and the latter is used in explaining the inertia of demand. To show the validity of the model, an empirical study is carried out using the data of the world DRAM market.
