Innovation Cosystems are Conceptualized as Organizational Networks of Economic Actors, Technologies and Social Contexts that Interact for Knowledge Production, use, and Adaptation. This Paper Proposed a Conceptual Framework to Describe Value Co-creation of Organizational Networks Engaged in Technology Innovation. We Adopted Theory-Based Approach by Integrating the Perspective of Service-Dominant (S-D) Logic Into the Evolutionary Model of the Triple Helix. The Framework Gives a Plausible Explanation on how Actors Collaborate to Create Value in Dynamic Contexts of an Innovation Ecosystem. The Innovation Ecosystem can be Considered as a Composite of Sub-Ecosystems, Including Knowledge, Sectoral, and Business Ecosystems. When these Sub-Ecosystems are Recursively Transformed by Coordination of Functional Mechanisms that Serve Value Co-creation in the Innovation Process, the Innovation Ecosystem will be Re-Organized and Evolve. The case of the Digital Living Network Alliance (DLNA) was Examined to Demonstrate the Fundamental Mechanisms for Value Co-creation that was Described in the Framework. The case Study Indicates Features of Value Co-creation when Implementing Innovation in Organizational Networks.

Evaluating the temporal and spatial changes in the ecosystem service value (ESV) of the Sanjiangyuan Nature Reserve is important for understanding the impact of human activities on natural ecosystem and guiding ecosystem restoration and environmental pollution control. In this study, remotely sensed land-cover data and the equivalent factor method were used to analyze the spatiotemporal evolution characteristics of the ESV in Sanjiangyuan Nature Reserve from 1992 to 2015, and regression analysis was employed to determine the factors driving changes in the ESV. The results show that grassland was the main type of ecosystem in the study area, and the transformation of grassland into bare areas was the primary change in land cover. Additionally, the ESV in the study area first decreased and then increased, with an annual growth rate of 0.69%. The ESV mainly increased in the north of the Yellow River's source area, and mainly decreased in the northwest of the Yangtze River's source area. Finally, the gross output value of agriculture, urbanization rate and proportion of secondary industry were found to be the main factors driving the ESV in the study area.

This study is to evaluate economic value of the ecosystem service benefits of the marine forests provided to our society on the basis of the global standard valuation manual. The main results of this study are summarized as follows: First, the ecosystem service benefits of marine forests are worth 771,121,551 won per hectare for a year in Korea. Second, when evaluating value based on the services benefits of the marine forests, as resource provisioning service, the annual value of the fishery potential production amounts to 58,512,271 won per hectare. The annual value of the environmental and regulatory services is estimated to total 29,574,000 won per hectare including 546,488 won per hectare for climate regulation, 85,342 won per hectare for pollution purification, and 28,942,170 won per hectare for erosion protection. The annual value of the culture and tourinsm services is estimated to total 15,317,647 won per hectare including 5,011,765 won per hectare for skin scuba service and 10,305,882 won per hectare for sea fishing. Also, the aunnual non-use value is estimate to 637,800,000 won per hectare. Third, assuming that the value of the sea forests increases proportionally to the unit area, the marine forests can be valued at 12.7 trillion won per year based on 12,208.2 hectares of marine forests creation area and 4,272.6 hectares of natural seaweed beds. Fourth, the total economic value of the marine forests can be estimated at 244 trillion won in 2016, if the value of the marine forests permanently continues in the future by applying 5.5% of the social discount rate. The results of this study are expected to serve as a valuable information for improving awareness of the value of marine forests ecosystem and ensuring the validity of the marine forests creation policy by converting the value of the marine forests's ecosystem service into monetary units.

The interest on rural ecological landscape has recently grown on the part of policy makers for rural development. While considerable efforts and resources have been invested to preserve and utilize rural landscape, we still lack a systematic means to quantify and evaluate ecosystem service value of the rural landscape and management status. So this study suggests rural ecological landscape management indicator considering ecosystem service value. It consists of 28 criteria and 107 subcategories, which can be applied to rural village. And We have applied ecosystem service value assessment and resident's management status on three villages, Moondang village, Yonggye village, and Sesim village.

The purpose of this study is to investigate the role and function of tokens to form a healthy blockchain-based ecosystem. Tokens must be constructed in a way that enhances their desired behavior to grow into a healthy token economy. The actions required of ecosystem participants in designing tokens should enable each individual to receive appropriate incentives (rewards) and encourage voluntary participation in taking this action. Also, all ecosystem participants must design to make the token ecosystem self-sustainable by generating profits. For example, in Bitcoin's proof-of-work method, mining is designed as a desirable behavior. Token-based services should be designed to induce multiple engagements, to design penalties for undesirable behavior, and to take into account evolutionary development potentials. Besides, the economic value of the entire token ecosystem will increase if the value that is designed and designed to take into account the revolutionary Innovation Possibility is greater than the reward amount paid to tokens. This study will contribute to presenting relevant service model by presenting how to design tokens and criteria when establishing blockchain-based service model. Future research is needed to discover new facts through a detailed comparative analysis between Tokennomics models.

This study was conducted to suggest an assessment indices to evaluate the ecosystem services of the unique functions of wetlands as well as economic value provided by the village wetlands. The assessment indicators applied in this study were used by the RAM indices. The results of RAM assessment on the village wetlands in Cheonan city were analyzed by item and critical functions of the village wetland. They were derived by assessment indicators of ecosystem services, and the village wetland ecosystem were presented by Focus Group Interview (FGI). The 20 critical indices were selected from 52 different indices by analyzing the wetland function assessment items. 13 indicators excluding duplicate indexes by function, were selected as ecological service impact indicators. Finally, ecosystem services were evaluated by using AHP analysis to calculate the weight of each assessment indices and apply it to the 9 village wetlands. The results of this study confirmed that the functions of the village wetlands are compliant with the ecosystem services. Based on this assessment of the unique functions of wetlands, it will serve as a methodology for assessing ecosystem services. The study was also conducted on 49 wetlands in Cheonan. The detailed assessment of wetland ecosystem services based on the wetland ecosystem function proposed by this study, was further developed as a follow-up study. It suggested that the wetland areas should be compared and be used as a general standard. In addition to the assessment of the economic value of ecosystem services provided by the village wetlands, it would be useful to assess the unique features and convert them into value.

전라남도는 우리나라에서 50% 이상을 차지하는 섬과 갯벌을 가지고 있다. 특히 그중에서도 신안군은 가장 많은 섬 개수와 넓은 갯벌을 차지하고 있다. 신안군은 2개읍, 12면으로 구성되어 있고 약 1,000여개의 유 무인도 섬들이 산재해 있다. 섬과 갯벌이라는 독특한 생태계 특성을 가진 신안군의 생태계서비스 가치를 Costanza et al. (1997)의 생물군계에 의해 계산하였다. 신안군은 갯벌이 가장 높은 생태계서비스 가치를 나타내었다. 이러한 결과는 대부분의 섬에서 같은 결과를 보였고 특히 압해읍과 지도읍이 가장 높은 값을 보였다. 증도면의 경우에는 실제적으로 군내에서는 면적이 11위에 해당하지만 생태계서비스 가치는 전체에서 4위를 나타내었다. 현재까지의 연구 상황으로는 정확하게 생태계서비스 가치를 계산하는 것이 어렵지만 대략의 가치라도 측정해 보는 것도 중요하다고 판단된다. 신안군 전체의 생태계 서비스 가치를 살펴봄으로써 현재 가지고 있는 가치를 잘 보전하고 지속적으로 활용하기 위한 정책에 활용하는 것이 필요하다. 특히 갯벌이라는 독특한 생태계를 잘 보전하고 이를 올바르게 활용할 수 있는 시스템 구축이 절실하다. 이 결과를 바탕으로 앞으로 신안군 발전계획 등의 정책결정에 좋은 자료를 제공하고자 한다.
