The industrial community in a metropolis has played an essential role to keep business in a large city. This paper aims to analyze the realities of trade network among enterprises at Buksungro Tools Commercial Cooperative in Daegu. The urban style industrial community is found at Buksungro in Daegu. There are more than one hundred small-sized enterprises. Major trades among enterprises are occurred within and/or by the area. The long-term trade networks within the Buksungro Tools Commercial Cooperative have played the key role to maintain the industrial community. The trade relationship has depended on business networks based on social capital rather than commercial mechanism. The trade networks have been established through credit transactions as well as handling troublesome orders. The trade networks help to transfer technology and to learn the tacit knowledge among firms. The long-term trade networks are more influenced by the social accessibility than spatial accessibility.

The paper analyzes the effects of Korean venture businesses' external collaborations on their innovation performances, according to their collaboration partners and collaboration activities. The results show that the collaborations between Korean venture businesses and research institutions, and those between venture businesses and other venture businesses have significant positive effects on venture businesses' innovation performances, in terms of the numbers of the intellectual property rights, while the collaborations between venture businesses and large companies have significant positive effects on medium-sized venture businesses only. In addition, collaborative research and development, and technology transfer from big companies to venture businesses have given significant positive effects on venture businesses' innovation performances, while collaborative employee training and collaborative marketing have given significant negative effects on venture businesses' innovation performances. Furthermore, collaborations between large companies and their subcontracting venture businesses have shown even more significant effects on venture businesses' performances. The results show that the effectiveness of external collaborations of Korean venture businesses depends on collaboration partners, types of collaboration activities, and the size of collaborating venture businesses, implying that government programs for encouraging venture businesses to collaborate with external institutions should be carefully chosen for their innovation performance improvement.

It is true that Blockchain has been known as a core technology for cryptocurrency like bitcoin (BTC). It is caused by its rapid value rises. Now, one BTC is trading around 10,000 US dollars while it bought just less than one dollar at its first trading in May, 2010. Blockchain makes on-line transactions possible by the safe cryptocurrency swiftly based on P2P network and distributed public ledger while its on-line traffic is rapidly increasing. However, this technology has bigger potential in the fourth industrial revolution era and its application areas will be varied. The evolving intelligent information society needs to make new added value through utilizing, sharing and processing of useful digital information. Obstacles such as hacking and fraud often exist when transactions of digital properties, right transfers, etc. are done through digital network specialized with anonymity. It is expected that blockchain will be a definite solution in this regard. This paper addresses useful development directions and countermeasures for blokchain in the digital economy by analysis of its current status and issues.

4차 산업혁명의 도래와 더불어 ICT 기계, ICT 금융, ICT 의료, ICT 나노 등과 같이 기술분야별 영역의 장벽이 허물어지고, 학제간 연구(Interdisplinary Research)가 일상화됨에 따라 무형자산의 가치평가시에도 융합기술의 가치평가 모형에 대한 니즈가 증대되고 있다. 특히, 기술의 매매, 현물출자, 기술금융(투자유치, 담보 보증), 인수 합병, 청산 소송 등 다양한 용도로 사용되고 있는 기술가치평가 모형은 융합기술의 입력변수 결정에 대한 체계적인 로직을 제공하지 못하고 있는 실정이다. 일반적으로 실제 거래사례가 존재할 경우, 국제가치평가기준(IVS)에 의하면 시장접근법이 우선적으로 적용될 수 있다고 권고된다. 그러나 융합기술의 이전거래를 비롯한 평가 활용사례를 수집하기도 어렵고 그렇다할 평가모델이 존재하지 않는 것이 사실이다. 융합기술에 대한 기술 및 시장의 사업화 환경을 고려하는 경우 소득접근법 기반의 평가기법이 유용하게 활용될 수 있는데, 기술수명, 매출액추정, 할인율, 산업기술요소 등의 핵심변수 결정에 관한 정형화된 로직이 존재하지 않으므로 본 고에서 융합기술 사례에 대해 실용적으로 활용가능한 변수추정 로직을 제시하고자 한다. 기술수명의 경우, 복수 개의 국제특허분류(IPC)별 피인용특허수에 따라 가중 적용하여 수명 추정을 위한 기준값을 정하며, 사업화소요기간 및 비용의 경우 평가대상 융합기술이 속하는 업종별 메타데이터값을 가중평균하여 현금흐름 추정기간을 최종 도출할 수 있다. 소득접근법에서의 매출추정, 할인율, 산업기술요소 변수 추정 이외에도 로열티공제법 적용을 위한 로열티율 결정에 있어서, 융합기술이 응용가능한 산업(업종)별 매출액 기반으로 가중 적용하여 각 변수값을 산출할 수 있다. 본 연구에서 개발된 융합기술 가치평가 모형은 향후 기술의 융복합화 특성을 반영하여 적정 가치를 산출하는 평가 가이드라인을 제공할 수 있을 것으로 기대된다.

To promote the commercialization of high technology based start-up company, it is essential to activate technology trading for the Innovative Small & Medium companies which eager to acquire technology competitiveness through technology trading and facilitate financial system which provide Small & Medium companies with technology commercialization money. This study focus on enhancing credibility of technology valuation solutions through the improvement of the existing technology valuation solutions. The existing technology valuation solutions in practice have deficiency in reasonable valuation because of subjective technology factor's calculation. And the commercialization risk of high technology based start-up companies cannot be fully reflected in the existing valuation solutions. The high risk of technology commercialization acts as a hurdle in the facilitation of providing money for the start-up companies. The improved new model will have more acceptable objectivity and reasonably reflect the commercialization risk of start-up companies. The new model has two distinctive features compared to existing solutions. The new model newly adopts commercialization success factor which reflects the risk of high technology based start-up company. And the new model excludes technology factor which is controversial among interested parties. The exclusion of technology factor will improve the objectivity of technology valuation and the adoption of commercialization success factor will solicit investor and capitalist who concern the high risk of technology based start-up companies. In conclusion, the improved new model is expected to activate technology trading and facilitate the money market through which high technology based start-up companies raise commercialization money.
