제1차 벤처붐을 겪은 이후 후기에 안정된 기업에 투자를 선호하는 벤처투자방식의 변화가 나타나고 있다. 기업성장단계에서 초기에서 중기에 있는 기업의 경우 자금의 부족을 경험하며, 지속적인 성장을 위해서 정부 R&D자금 지원을 받고 있다. 하지만 정부의 R&D자금 지원이 과연 지속가능성 측면에서 경쟁력이 있는 기업에게 지원되고 있는가에 대한 우려의 목소리가 있다. 본 연구는 제조업에 속하는 벤처기업을 대상으로 DEA 효율성 분석을 실시하였다. 이를 통하여 제조업에 속한 핵심 산업인 ICT제품과 같은 첨단제조와 기계, 자동차와 같은 일반제조에 속한 벤처기업의 효율성을 살펴보고, R&D지원을 받는 벤처기업과 그렇지 않은 기업을 비교분석한다. 추가로 두 집단 간의 특성(혁신성, 성장성, 수익성, 안전성)이 1년간 어떻게 변화하였는지 분석한다. 실증 분석결과, 제조업에 속한 R&D자금을 지원받는 벤처기업의 경우 그렇지 않은 기업보다 효율성이 낮은 것으로 나타났다. 이는 지원을 받은 벤처기업이 지속가능한 측면에서 비지원기업 보다는 경쟁력이 낮음을 시사한다. 그리고 1년간의 여러 특성의 변화를 살펴본 결과, 혁신성에서는 지원기업이 높은 성과를 창출하였지만, 수익성에 있어서 비지원기업 보다 저조한 것으로 나타났다. 따라서 정부의 R&D지원이 지속가능성 측면에서 경쟁력이 있는 기업에게 지원되기 위해서는 기술력뿐만 아니라 경영 효율성을 고려하는 시도가 필요하다.

This study analyzes the relationship between R&D input and performance using panel data from the defense industry. A research model is established based on the R&D logic model, and the study sample consists of a strongly balanced panel data (n=351) empirically analyzed using panel linear regression. Results identified that defense improvement expenditure has a positive influence on the R&D input, and R&D input positively affected patents using a 5-year time lag. In addition, R&D input positively impacts economic performance, including sales and profit. Hence, the major finding includes R&D inputs have statistically significant effects on economic outcome and the R&D logic model featuring a time-lag.

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.

R&D (Research and Development) investment by companies and the government continues to increase, and the total R&D expenditure of public and private sectors in 2021 reached KRW 102 trillion, and the ratio of R&D investment to GDP was 4.96%. It ranks second in the world after Israel. This study analyzes the current status of the domestic R&D service industry and the research and development (R&D) innovation ecosystem based on the business activity survey data of the National Statistical Office in terms of improving R&D productivity of domestic R&D investment that has exceeded 100 trillion won, and analyzes the global R&D service industry and analyzes the global research service industry and R&D service Industry support government policy As a result of the analysis, in the domestic R&D ecosystem, the R&D outsourcing demand of service companies is rapidly increasing, compared to the stagnant R&D outsourcing demand of traditional manufacturing companies. In order to respond to these changing demands for technological innovation, this study suggests balanced support for R&D outsourcing for manufacturing and service companies, expansion of domestic R&D outsourcing, establishment of R&D outsourcing strategies specialized for the service industry, establishment of an open R&D ecosystem, and innovation in connection with materials/parts/equipment strategies.

In that economic growth strategy through maximizing input would not working anymore in the rapidly changing economic environment, now we should focus on the improvement of firms' efficiency. This study estimate the efficiency and determinants of the efficiency using the panel data of 938 Korean manufacturing firms which ranked in high R&D investment firms during 2005~2018. We found that both R&D intensity as R&D input and patent stock as R&D output increase the efficiency of firms independently. And firm size, debt ratio, profitability also affect the firm's efficiency.

The purpose of this study is to empirically examine the impact of enterprise R&D investment on international trade in Korea under the new Normal Era. In order to test whether the time series data of trade variables are stationary or not, we put in operation unit root test and cointegration test. Based on VECM (Vector Error Correction Model), we also apply impulse response functions and variance decomposition to estimate the dynamic effects in the short-run and long-run. The results show that the relationship between enterprise R&D investment and international trade (export and import) exists in the long-run as well as in the short-run. The results of applying impulse response functions and variance decomposition also indicate that the impact of enterprise R&D investment on international trade is positive, and a significant portion of fluctuations in the trade variable is explained by enterprise R&D investment. Therefore, enterprise R&D investment must be continuously increased to improve economic growth with promoting trading competition power in Korea under the new Normal Era.

Startups play an important role in economic growth and job creation in niche markets, thus governments regularly expand their research and development(R&D) budgets accordingly. As stratups are more dependent on governments to compensate for insufficient resources and capabilities than large and medium-sized companies, trust in government policies will be important. In this study, we analyzed the impact of startups' trust in government R&D policies on innovation performance. There were three major results. The first result is that government R&D investments in startups increase innovation performance in the manufacturing and high-technology industries but did not affect other industries. The second result is that trust in government R&D policies increased innovation in high-and medium-high technology and manufacturing industries. The third result is that trust in government R&D policies affects innovation before, during, and after evaluation of support process. We analyzed the importance of trust to the effectiveness of government R&D support to determine how to effectively provide it. The results show that governments need to differentiate the types of R&D support they provide according to the target firm's technology level and whether they are a manufacturing company and that appropriate R&D support mechanism should be developed for low-technology and non-manufacturing companies. Finally, governments should allocate resources and make fair and transparent decisions to help companies grow, not to better supervise them.

One of the important issues in finance literature is how the capital structure influences firm performance. This paper aims to investigate this relationship by focusing specifically on the entertainment industry. Taking into account the growing importance of research and development (R&D) activities in the industrial revolution 4.0 era, an additional goal of this paper is to examine how the R&D intensity moderates the relationship between the capital structure and firm performance, particularly in the entertainment industry. We find that the relationship between the capital structure measured by debt ratio and the firm performance in the entertainment industry shows distinctive features from those obtained from entire industries. While the negative influence of the increase of debt ratio is strong and consistent with various proxies when using a sample with entire industries, we cannot find this distinctive influence among entertainment enterprises. The moderating effect of R&D investments on the negative influence of debt ratio on the firm value, observed in the sample with entire industries, is not found in the sample composed of entertainment companies. These findings suggest that the influence of the debt level on firm performance and the role of R&D investments in this relationship in the entertainment industry are perceived and evaluated differently by financial market participants.

The relationship study between SMEs' R&D and business performance is important research subject. The objective of this paper is to evaluate whether the effectiveness of government's R&D subsidy for SMEs is supported. The positive perspective is that the support policy stimulates the SMEs innovation activities including R&D and thus contributes to the performance, but the negative view is that the support policy rather decreases the firm's own R&D investment and thus the result is not necessarily promising. This paper is to evaluate the effectiveness of government subsidy on SMEs' R&D. This study suggested DID and Random Effect Models for analysis using the panel data of 2,807 SMEs in manufacturing sector. The data was collected from the 'Survey on SMEs Technology & R&D 2011' conducted by Korea Federation of Small and Medium Business. The results are as follows. First, government's subsidy has crowded out 4.7% of beneficiary's internal R&D investment. Second, government's subsidy has increased 27.3% of beneficiary's R&D intensity in spite of 4.7% internal R&D investment reduction. Third, government's subsidy didn't have a relationship with firm performance but the R&D intensity made positive influence on the firm performance. Finally, R&D intensity has increased the 6.7% of firm performance. These results mean that government's subsidy give a positive impact on SMEs' performance through R&D intensity with relatively small crowding-out effect.

Research and Development(R&D) investment is an issue of central importance in any economy. In this paper we analyze the relationship between R&D spillovers and trade-related variables, using a two-stage model where duopolists simultaneously decide on R&D in the first stage and engage in Cournot competition in the second stage. We characterized and compared the free-trade and trade-restriction R&D equilibrium in a two-stage game of R&D investment followed by Cournot market competition. We also assessed the impact of varying the R&D spillover on the equilibrium outcomes and tariff. We showed for both free trade and protection cases that there exists a unique symmetric solution(subgame perfect Nash equilibrium). As the solution, while analytical, cannot be stated in closed form, we resorted to numerical experiments to investigate the equilibrium results. Our estimates indicate for both free trade and protection cases that the level of R&D investment and the rate of R&D expenditure decrease as the degree of R&D spillovers increases, and that there is an inverse relation between the degree of R&D spillovers and level of protection. The latter implies that the larger the degree of R&D spillovers, the lesser the level of protection.
