Using 1855 observations from 5 years-371 firms panel data during 2010 to 2014 in Chinese stock exchanges, this study examines the impact of managers' ownership on R & D expenditures. The empirical study finds that when firms are state-owned, managers' ownership have negative relation with the level of R & D expenses as well as the likelihood of executing R & D investment, implying that managers are less likely to invest in high risky projects due to managerial ownership's entrenchment effects to pursue private benefits rather than alignment of interest effect as shareholders. The empirical study also finds that when firms are private-owned, managerial ownership are inverse U shaped related to the level of R & D expenses, implying that managers are less likely to invest in high risky projects due to increasing risk aversion resulting from concentration of private wealth at its high level while managers are more likely to invest in high risky projects due to increasing incentives as shareholders at its low level. The results support that the effects of managerial ownership on R & D expenses may be different according to the ownership type of Chinese listed firms.

The relationship between R&D investment and subsequent change has been mostly confirmed under additional influencing factors, with the form of innovation investments. The research assumes that a firm adjusts its R&D spending in accordance to performance feedback. It is argued that an increased fluctuation of a firm's R&D expense is related to a reduced performance. This hypothesis is tested on SME in World class 300 Projet by SMBA. Using panel data models, instability measured by SD is related to performance levels measured by ROA, ROE & PM. Results support the proposed relationship between R&D expense instability and the subsequent performance. Although a causal link cannot be clearly established, the results indicate that firms with a lower performance have higher R&D investment fluctuations, possibly being more responsive to performance feedback.

This study is intended to demonstrate how different factors induce the Korean government's direct investment in research and development according to the type of business enterprise in Korea. We analyzed that what factors made the government directly invest in research and development by using a total of 18,272 company panel data, which are not limited to specific industries or government-led research and development (R&D) programs. The results showed that the direct investment for R&D by the government led to the increase in the number of researchers in SMEs. For major companies, the direct investment resulted in the increase of sales and company's own R&D expenses. Moreover, this study found that government's direct support for R&D even led to the decrease of SMEs' own R&D expenses; however, this result was not statistically significant. In addition, the most significant factor to increase both SMEs' and major company's own R&D expenses was the sales amount of the company, rather than government's direct investment for R&D. The factor that increases sales was the company's own R&D expenses, rather than government's direct investment for R&D. Through the analysis using Mixed Effects Model, this study suggested the policy should be changed to make SMEs invest in its own R&D expenses, rather than to secure researchers of SMEs by government's direct investment for R&D.

Since the specifications of public services in broadcasting-telecommunication convergence environment are not standardized, the public services should be developed and presented by each IPTV service provider, and therefore it is worried that public organizations and IPTV service providers may invest in the public services redundantly, which are managed inefficiently. To resolve those problem, in this paper, the service and network interfaces among multiple public organizations and multiple IPTV service providers and the interactive VOD-type public service providing system of one source multi-use based on ACAP-J are proposed. The proposed system can be utilized in the standard platform of the evolved new public services. And the used technologies can be utilized as a guide for the development of new services.
