Prior research in R8ED innovation in Korea has been centered around the 'three-stage development model,' which hypothesizes that the Korean innovation process goes from the introduction (of foreign technology) stage, through assimilation stage to the final modification stage. As Korean economy shifts from traditional industry-led development to innovation-centric development, such an approach loses sight of the whole picture. The current study argues that a new framework is required for adequate analysis on newly arising innovative patterns in Korea, emphasizing source technology development and technology leader strategy. For this purpose, we propose the 'Jigsaw Puzzle Model' of technology development, which is then verified by an in-depth analysis on the innovation processes of 3 representative IT products of Korea, DRAM, TH LCD, and CDMA. The model suggests that Korean innovation model is a dynamic, efficient amalgamation of foreign-acquired and dependent technologies, based on internally accumulated technological resources. The model explains better how Korean firms are achieving a rapid catch-up of technological gaps with advanced nations and are able to transfer from the technology follower to the leader position.

This study identified the appropriateness of acceptance models of smart clothing and differences in the hypothesis of the path to clothing acceptance by classifying consumers depending on the level of technology innovation and fashion innovation through the extended TAM (Technology Acceptance Model) presented by Chae (2009). 815 copies of data were collected from adults over twenty living in major South Korean cities and analyzed them using a SPSS 15.0 and AMOS 5.0 package. Based on the average value of technology innovation and fashion innovation, the respondents were classified into: Group 1 with high technology innovation and fashion innovation, Group 2 with high technology innovation but low fashion innovation, Group 3 with low technology innovation but high fashion innovation, and Group 4 with low technology innovation and fashion innovation. The appropriateness of models for the four classified groups was verified. The analysis proved that an extended TAM for each classified group explains the acceptance process of smart clothing; especially the appropriateness of model of Group 1 and Group 4 was comparatively higher than other groups. Perceived usefulness was revealed as the key variable that affects consumer attitudes to accept smart clothing. Perceived ease of use has indirect positive effects on consumer attitudes passing through perceived usefulness and clothing involvement partly exerted impacts on consumer attitudes and the intention of acceptance. The mediating role of attitudes to explain the intention of the acceptance of smart clothing is high and suggests that it is necessary to take a positive role to help the consumer perceive the functional and useful aspects of the clothing.

Cloud is emerging as a key factor in digital transformation. In particular, the industry is paying attention to cloud as a key factor in economic revitalization after COVID-19. In this economic environment, cloud companies can survive only through continuous innovation. In this study, we propose the innovation types of cloud companies using the meta model, which is a high-level conceptual model that generalizes various corporate activities. The proposed cloud company innovation type applies a conceptual model divided into two axes such as the corporate value chain and the business management layer. The contribution of this study is to provide a basis for research in a new academic field called corporate innovation in the cloud domain, and to provide decision-making tools for diagnosing innovation levels or exploring innovation directions for cloud companies.

Over the last decade, some Korean enterprises have emerged to become global players in their specialized products. How have they achieved such tremendous technological progress in a short period of time? This paper explores that question by examining the characteristics of technological innovation activities at major Korean enterprises. The paper begins with a brief review of the stages of economic growth and science and technology development in Korea. Then, the existing literature, explaining the Korean innovation model, is analyzed in order to establish a new framework for the Korean innovation model. Specifically, Korean firms have experienced three sequential phases, and thus, the Korean model, at the firm level, can be coined as "path-following," "path-revealing," and "path-creating." Then, the stylized facts in the first phase (path-following) and the second phase (path-revealing) are discussed, in the context of empirical evidence from the areas of memory chips, automobiles, shipbuilding, and steel. In terms of technology development, the Korean model has evolved as "collective learning" in the first phase, "collective recombination" of existing knowledge and technology in the second phase, and is assumed as "collective creativity" in the third phase. Ultimately, all three can be classified as "collective creation". Korean firms now face a transition in the modes of technological innovation in order to efficiently implement the third phase. To achieve remarkable progress again, as they did in the past, and to sustain the growth momentum, Korean firms should challenge new dimensions such as creative technological ideas, distinctive technological capabilities, and unique innovation systems -- all of which connote 'uniqueness'. Finally, some lessons from the Korean technological innovation experience are addressed.

Catch-up is a well-known and familiar terminology for innovation scholars in developing countries such as Taiwan, Korea and China. The strategy, however, is too difficult to perform in each industry. This study looks into a catch-up strategy that Apple and Xiaomi used and examines the results on the creative imitation of business model in the smartphone industry. It is quite surprising that even Apple is based on catch-up strategy. They wanted to catch-up Nokia. Our case study shows that these two companies quickly caught up with the leaders, and the common feature of their strategy is characterized as creative imitation of business model. Creative imitation of business model is different from creative imitation of innovation. Furthermore, this research confirms that the creative imitation of business model leads to aggressive creative innovation.

Literatures on open innovation have two major limitations. First, either on a firm level or on an industry level did they analyze the open innovation issues. The results of a firm's innovation can be diffused through the whole network and the firm can learn back from the network knowledge. Prior literatures did not consider the feedback loop among firms and network in which the firms are involved. Second, most open innovation research had a static perspective on firm's innovation performance. Since the diffusion, spill-over and learning among network members are involved over time, the open innovation is intrinsically dynamic. From the dynamic perspective, we can appreciate the fundamental attributes of the open innovation network which involves diverse firms, research institutes, and universities. In order to overcome the limitations, we suggest a dynamic model for open innovation network. We build an agent-based model which consists of heterogeneous firms. The firms are connected through a scale-free network which is formed by preferential attachment. Through the diverse scenario of simulation, we collect massive data on the firm level and analyze them both on firm and industry level. From the analysis, we found that, on industry level, the overall performance of open innovation increases as the internal research capability, absorptive capacity, and learning curve coefficient increase. Noticeably, as the deprecation rate of knowledge increases, the variability of knowledge increases. From the firm level analysis, we found that the industry-level variables had a significant effect on the firm's innovation performance lasting through all the time, whereas the firm-level variables had only on the early phase of innovation.

An innovation diffusion model is proposed model consists of three classes, namely, a non-adopter class, adopter class innovation-I, and adopter class innovation-II in a partially competitive and cooperative market. The proposed model is analyzed with the help of the qualitative theory of a system of ordinary differential equations. Basic influence numbers associated with first and second innovation $R_{0_1}$ and $R_{0_2}$ respectively in the absence of each other are quantified. Then the overall basic influence number (R₀) of the system is assessed for analyzing stability in the market in different situations. Sensitivity analysis of basic influence numbers associated with first and second innovation in the absence of each other is carried out. Numerical simulation supports our analytical findings.

Although the importance of the service sector has been highlighted recently, service innovation remain under-researched by scholars. Innovation research based on manufacturing sector suggests that innovation strategy varies according to the objectives of innovation and has a positive influence on firm performance. To investigate the path that links the objectives of innovation, innovation strategy used and firm performance, this study develops a conceptual model of service innovation from the literature and tests the Structural Equation Model(SEM) using STEPI (Korea's Science and Technology Policy Institute) data. We could identify the causal relationships both between the objectives of innovation and innovation strategy and between innovation strategy and firm performance in service as in manufacturing, but we also found that the results of the empirical study for the service industry, in particular, the empirical results on the relationship between the aims of innovation and innovation strategy used, are quite different from those for manufacturing.
