In these days of severe changes in the environment and economic slump, it is indispensable for firms to cope with the environment effectively. This study is an attempt to investigate the mechanisms through which output sector munificence and dynamism affect distribution channel performances, such as, satisfaction, trust, and commitment. Especially, this study focus on moderating effects on distribution channel integration that has not been investigated in the past. For the purpose of empirical testing, 70 corporate channels, 120 contractual channels, and 100 conventional marketing channels have been selected and analyzed. According to the result from moderated regression analysis, munificence strengthens distribution channel performances, while dynamism weakens them. And integration reinforces the effects.

본 연구는 서로 다른 조건에서 질산화를 유도한 반응기의 군집동태를 살피기 위해 RAPD, ARDRA, DGGE와 같은 기법들을 적용시켜 반응기 초기의 슬러지 구성 군집의 상태 와 질산화 유도후의 군집 변화를 살펴보고자 하였다. 결과적으로 1.5 kb정도의 165 rDNA를 이용한 RAPD와 ARDRA에서는 RAPD에 의한 군집 Patterns변화가 훨씬 다양했으며, 250 bP정도의 PCR산물로 분리를 시도한 DGGE에서도 비교적 예상했던 바와 같이 군집이 단순화되는 양상을 볼 수 있었다.

While a number of studies have recognized the importance of environment of channel systems and consequences of changed environment, only limited studies have dealt with this issue theoretically and practically. The purpose of this study is to empirically validate whether one dimension of environment, called dynamism, has an influence on the relationship characteristics such as transaction specific investment, opportunism and conflict or not; further, it is designed to delve into whether these relationship characteristics have any influence on one crucial relationship quality, 'trust' and its two constituent dimensions - credibility and benevolence. In order to provide empirical validation, a survey was conducted to 163 sales office managers at a major newspaper publisher in Korea. An analysis of the data retrieved from this survey indicated that while environmental dynamism has a positive influence on the publisher's opportunism and conflict perceived by the sales office managers, it did not show a direct influence on the transaction specific investment made by the publisher. Furthermore, while publisher's transaction specific investment had a positive influence on the credibility and the benevolence respectively, publisher's opportunism and level of sales office conflict had a negative influence on the credibility and the benevolence respectively. Currently, a publisher is facing an unprecedentedly dynamic environment. This study should provide ample implications for the publisher in establishing trust, which is a crucial condition in developing and maintaining a long-term successful relationship with its sales offices.

본 논문은 선행연구인 정회성${\cdot}$전대욱 (2005)의 모형을 중심으로 선행연구에서 미처 다루지 못한 체계 변화 및 모형 확장 등에 대해 다루고 있다. 선행연구에서는 우리나라의 참게 복원사업에 대한 개체수 동태모형(population dynamics)과 자원 경제학적 이론모형을 근거로 생태${\cdot}$경제 통합시스템에 대한 동태모형을 도출하고 이를 통해 실증분석을 수행하였는데, 본 논문에서는 이 통합 모형에 있어서 밀도 제약(density restriction)과 공식 행위(cannibalistic behavior), 주민참여에 의한 환경개선 등 일련의 가정들에 대한 확장을 통해 보다 일반화된 통합체계 및 시스템 다이내믹스 분석을 제시한다. 이와 같은 모형 확장 및 파라메터의 내생화 등은 관련 피드백 루프들의 변형과 추가 등을 의미하며, 이와 같은 변화를 포함한 확장 모델을 제시하고 분석함으로써 참게 복원사업에 대한 보다 폭넓은 논의를 제시하고자 한다.

This study examines how eco-innovation contributes to the exports of environmentally-friendly products using the dynamic panel model. The results reveal that the adjustment in the exports exists to recover the long-run equilibrium with sluggish adjustment speed. In addition, the results show that environmental patent applications and environment-related R&D expenditures are beneficial for enhancing the environmentally-friendly exports. While the environmental patent applications are associated only with an increase in the exports of products for resource management, the environmental R&D expenditures contribute to the exports of pollution management products, cleaner technologies and products, and resource management products. Moreover, as the long-run effects of eco-innovation on the exports become greater than the short-run effects, it appears that public eco-innovation is more likely to support future exports than private eco-innovation.
