이 연구는 기업벤처캐피탈에 대한 거시적경제, 산업구조적 관점에서 기업벤처케피탈 투자에 영향을 미치는 요인들에 대해 탐색한다. 기업벤처캐피탈 투자에 관한 기존 연구들이 모기업의 사업 다각화, 신규 사업 진출을 위한 기업벤처링(Corporate Venturing) 등 모기업과의 관련성을 중심으로 기업벤처캐피탈의 정체성과 투자목적에 대해 논의해온 것과 달리, 본 연구는 변화하는 거시경제적, 산업구조적 환경적 요인에 영향을 받고 이에 대응하는 독립적, 재무적 투자자로서의 기업벤처캐피탈의 정체성에 주목하여, 기업벤처캐피탈 투자에 미치는 영향을 분석한다. 이를 위해 구체적으로 산업 호황, 외생적 위기, 경제 성장, 산업 내 경쟁 강도 등과 같은 거시적 요인들이 기업벤처캐피탈 투자에 미치는 영향에 대해 1996년부터 2017년까지 84개 미국 기업벤처캐피탈의 2,306건의 투자데이터를 기반으로 실증분석하였다. 분석결과 일반적인 독립벤처캐피탈과 마찬가지로 산업이 호황이고, 경제가 성장할 때는 기업벤처캐피탈도 투자를 늘리고, 외생적 위기가 발생하거나, 기업벤처캐피탈들 간 경쟁 강도가 강할수록 투자가 줄어들 것이라는 가설이 모두 지지되었다. 주로 모기업과의 관계, 피투자회사와 모기업 사업의 관련성 등을 중심으로 기업벤처캐피탈 투자에 대해 논의했던 선행 연구들과 달리, 기업벤처캐피탈의 재무적 투자자로서의 정체성과 기업벤처캐피탈 투자에 미치는 거시경제적, 산업구조적 요인들의 영향에 대해 환기함으로써 기업벤처캐피탈 투자에 대한 논의의 폭을 확장하고, 기업벤처캐피탈 투자의사결정자들에게 거시경제적, 산업구조적 요인들에 대한 대응을 시사한다는 점에서 의의가 있다.

The studies of density effect or the effect of population density on plant growth have been done on basis of dry matter production with Raphanus acanthiformis var. simoodaeguen, Brassica campestris var. Pekinensis f. namsounsokoombecheu, Oryza sativa f. kimmajae and O. sativa f. mangyeng grown in the various spacing. 1. In the early period of plant growth in dry weight was not different each other among varying densities, but as time advanced the plant grown vast space grew sufficiently compared with those of narrow one. 2. Iogarithmic relation between the growth of plant (W) and the density (P), log W-log P in the material plants, were approximated by two straight lines, one was horizontal line and another inclined: the former showed non-competition density and the latter competition density addition to these the point interlinking both lines were implied of the optimum density per unit land area at certain growth period. 3. The values of relatvie growth rate (RGR) and net assimilation rate (NAR) were decreased as increase in the density, while those of leaf area ratio (LAR) were rather increased in the same condition, with minor exception. From these results and relation between the productive structure and due to lack of the recieved light intensity owing to the mutal shading among the plants.

Purpose While the popularity of C2C auction platforms such as eBay is gradually decreased, this domain is still undermined to explain online bidding behaviors. Online bidders sometimes engage in impulsive bidding due to some of the online auction characteristics. Therefore, this study develops and tests a model of the impulsive bidding exhibited by online bidders in C2C auction platforms. Based on S-O-R framework, our model posits that both perceived time-pressure and competition intensity affect cognitive absorption which ultimately influences the impulsive bidding. Design/methodology/approach This study collected survey data from 214 C2C auction participants, who have prior experience on impulsive bidding and tested both measurement model and structural model by using CB-SEM (covariate-based structural equation modelling) technique. In this study, by using AMOS 20.0, we tested the measurement model for its overall fit, item reliability, and validity and further conducted the structural model to test our proposed hypotheses. Findings Based on our results, we found that perceived tim-pressure and competition intensity were positively related to cognitive absorption. We also found that the cognitive absorption was positively associated with impulsive bidding behavior. In this study, by developing our research model in S-O-R framework, we provide an alternative theoretical mechanism to describe online impulsive bidding behavior.

The Small and Medium Enterprise is currently getting more attention from the Indonesian government as the contribution of this sector to the regional and national income has increased. Though the government is providing a lot of attention as well as facilities to the small businesses in the manufacturing sector, they face intense competition. Thus, the small enterprises need to ensure that they achieve good business performance. This research aims to investigate the role of entrepreneurial intensity and innovation in improving the performance of small businesses in Indonesia. For this purpose, one hundred and eighty-six small business owners participated in the survey. The data was analyzed using Structural Equation Modelling. The hypothesis results show that entrepreneurial intensity and innovation have a proven role in business performance of small enterprises. Entrepreneurial intensity in particular, significantly impacts innovation and exploration. And innovation is crucial for business performance. The results imply that to increase business performance, the owner and the manager also need to raise their entrepreneurial spirit, as it can enhance their willingness to explore and use their business experience to do more innovation activities. The more innovation is done by the company; the business performance is more likely to improve.

In order to assess the attractiveness of the hospital industry, the competitive environment of the industry was analyzed. With the employment of Michael Porter's five forces model' the deciding factor was examined and applied to evaluate the intensity of the competitiveness in the hospital industry, and then the structure and attractiveness in hospital industry was assessed. The subject of this study was hospitals that have over 500 beds. Main findings are as follows. 1. Out of 5 factors deciding competitiveness, the pressure from newly opened hospitals and the competition between existing hospitals, were both high in intensity; this makes hospital industry less attractive. The pressure from the substitutes and the pressure from the negotiating power of consumers and suppliers were low; this makes hospital industry more attractive. 2. Overall intensity of competitive pressure pressure for existing hospital industry that have over 500 beds was rather low, consequently the attractiveness of the industry was evaluated quite high. These findings, however, were not solid enough to endorse the attractiveness of the industry. 3. It was understood that future industry would have bigger pressure/ competition so that the attractiveness for the relevant hospital industry would be decreased. This study has its limitations. As the evaluation of competitive factor was not grounded on quantitative data, its objectivity could be questioned. Also, the overall result of each factors could be distorted as it was calculated with same weight against individual factor. This study has its significance in that the specific hospital group was viewed as one industry, and its attractiveness as a potentially profitable industry in which worth investing was estimated, with all factors considered. With this key result, hospitals industustry could work out a plan to enhance the status of hospitals, allowing hospitals to get assistance in making strategic decisions such as mergers, cooperations, and new establishments.

This paper analyzes the impact of the change in telecommunication regulation changes including the unification of telecommunication service on network investment. The unification of telecommunication service plays a role of separating behavior regulation from entrance regulation and reducing entrance constraints. Therefore, it is expected that the market spillover effect is high through the improvement of behavior regulation. In addition, the effects of the other regulation changes in the 2010 Telecommunications Business Act revision are analyzed. This paper discusses critical factors affecting the decision making process in respect to the firm level and analyzes the impact path guiding investment and innovation. The key findings are as follows. First, the impact of entrance deregulation depends on the intensity of deregulation. If the intensity is not high, this regulation increases the incentive on investment and innovation. However, if the intensity is high as shown in abolishing of licensing, it affects the incentive negatively. Second, if interconnection regulation focuses on existing facilities or the intensity is not strong, this light handed regulation might increase investment and innovation. However, if interconnection obligation is expanded to the facility not constructed or the facility applying new technology, this regulation might deteriorate investment. Third, price deregulation increases the competition of service but it also increases the business opportunity, which means positive effect on investment. Finally, the paper proposes the guideline for telecommunications policy.

The goal of this study is to determine, based on survey results, the underlying factors that affect the intention of the farmers who have not adopted the Hazard Analysis and Critical Control Points (HACCP) system for the rearing phase of pig production to adopt this system in the future. The research model for this study was con structed based on strategic contingency theory, the theory of the diffusion of innovation, and the technology acceptance model (TAM). Using structural equation modeling with partial least squares (PLS), this study analyzes the effects of the intensity of competition, the environmental uncertainty, the innovativeness and self-efficacy of the individual farmers, and the impact of the credibility of the Agricultural Technology Service Center (ATSC), which acts as the principal agent of technology dissemination and as a leader of change, on the perceived usefulness of technology and the farmers' intention to adopt the system. The results of the analysis are as follows. First, with regard to the underlying factors affecting the intention to adopt the new system, the intensity of competition within the industry and the institutional credibility of the ATSC were inferred to underlie the perceived usefulness. Second, institutional credibility has a positive impact on the perceived usefulness of the system, and the perceived usefulness, in turn, has a positive impact on the intention to adopt. The perceived ease of use also has a positive impact on the intention to adopt. Because the factor that has the biggest impact on the intention of a farm to adopt is the credibility of the ATSC, it is crucial for extension organizations, such as the ATSC, to make greater efforts to promote the expansion of the HACCP system. Because farmers feel that the implementation of the HACCP system is an instrumental strategy for coping with the high intensity of competition within the industry, they attempt to gain a competitive edge through the production of safe livestock products.
