본 논문은 생산성 수준과 생산성 성장에 대한 노동조합의 효과를 분석한 연구문헌에서의 이론과 실증 연구결과들을 조사 분석한 것이다. 노동조합과 생산성 수준 및 생산성 성장의 관계에 대한 이론과 연구결과들이 다양하기 때문에 노동조합이 생산성에 미치는 효과의 방향이나 크기에 대해서는 결론적으로 단언하기는 어렵고, 결국 적절한 모형과 자료를 가지고 실증분석을 해봐야 알 수 있는 문제이다.

This paper empirically examines how controlling strategic goods affects productivity by focusing on Korean industries from 2015 to 2019. We hypothesize that strategic goods control positively affects productivity because it promotes international trade by making up for market failures, building up national credibility, and stabilizing market environment; in turn, international trade contributes to productivity growth. The regression results are congruent with our hypothesis. The effects of strategic goods control on productivity were positive and statistically significant in general. These positive effects were more prominent in the group of industries that include strategic goods and, thus, are technologically intensive. The results also support that international trade is a key medium for the effects of strategic goods control on productivity. Consequently, our empirical results support government policy on strategic goods control, ensuring that strategic goods control can contribute to economic growth by reducing diplomatic friction and stabilizing the global market.

본 연구는 외국인직접투자가 투자 대상 기업 및 동일 산업 내 다른 국내기업들의 생산성에 미치는 효과를 분위회귀(quantile regression)모형으로 분석하였다. 분석 결과, 제조업에서는 외국인직접투자가 투자 대상 기업에 통계적으로 유의한 양(+)의 생산성 효과를 가지며, 특히 생산성이 높은 기업군일수록 생산성 향상효과가 큰 것으로 나타났다. 또한 외국인직접투자는 동일 산업에 속한 국내기업들 중 생산성이 낮은 기업군에는 통계적으로 유의한 양(+)의 생산성 파급효과를 갖는 반면, 생산성이 높은 기업군에는 통계적으로 유의하거나 유의하지 않은 음(-)의 파급효과를 갖는 것으로 나타났다. 서비스업에서는 외국인직접투자 대상 기업이나 동일산업 내 국내기업들 모두 통계적으로 유의한 생산성 효과가 명확히 나타나지 않았다. 이러한 분석 결과는 외국인직접투자가 국내기업의 생산성에 미치는 효과가 기업의 생산성 수준에 따라 이질적(heterogeneous)이며, 통상적인 평균회귀(mean regression)모형 외에 분위회귀모형을 활용해 외국인직접투자가 생산성 분포에 미치는 효과(distributional effects)를 분석할 필요가 있음을 나타낸다. 또한 외국인직접투자의 생산성 향상효과를 극대화하기 위해서는 단순한 투자유치를 넘어 기업의 생산성 수준에 따른 외국인직접투자의 이질적 효과를 감안한 보완적 전략이 필요함을 시사한다.

The purpose of this study is primarily to analyse empirically the productivity effects of worker participation in capital by Korean employee stock ownership plan that had taken newly effect on and after January 1,2002, and secondarily to examine the impact of unionization on productivity. The analysis data are those of 150 firms that listed or registered on the stock market, and introduced ESOP. The result of this study can be summarized as follows. First, the worker participation in capitia have significantly a positive effect on productivity, but the magnitude of those effects vary according to estimation models and sectors. The elasticity of stock share owned by employees on productivity is from 0.03 to 0.24. Second, there is no unitary relationship between unionization and productivity. The coefficients of union dummy variable are positive or negative according to models and sectors as well as insignificant.

This paper investigates the productivity growth of four manufacturing industries employing TFP and Malmquist productivity indexes on data for 13 OECD countries covering 1977-1990, and estimates the effects of R&D investment on productivity growth. The results show that there is a large difference between these indexes, and that R&D effects on productivity using TFP and Malmquist productivity indexes are different in value and significance.

Extant research on firm innovation productivity is limited in measuring the innovation productivity, in which they measured firm innovation productivity by using either inputs or outputs of innovation. The present study complemented the extant research by employing Data Envelopment Analysis (DEA) approach to measure firm innovation productivity. Furthermore, this paper examined the effects of firms' external knowledge search, as one of open innovation practices, on firm innovation productivity, for open innovation activities are regarded as an influencing factor on firm innovation productivity in the previous literatures. Using the data of the Korean Innovation Survey (KIS) of manufacturing industries conducted in 2008, this study developed hypotheses in which we considered not only two dimensions of external knowledge search (breadth and depth) but also two subtypes of external knowledge search (market-driven and science-driven). The results found that searching deeply and market-driven search are positively related to firm innovation productivity, but science-driven search is somewhat negatively related to firm innovation productivity. Furthermore, market-driven search can mitigate the negative effect of science-driven search on innovation productivity.

Purpose - The purpose of this study is to clarify the mediating effect of profitability and activity in the relationship between productivity and stock return, assuming that the productivity of the company will affect share prices with the parameters of profitability and activity. Design/methodology/approach - The study extracted productivity indicators, profitability indicators, activity indicators, and share price-related indicators from 1999 to 2018 of non-financial enterprises listed on the securities market, and then classified them into three factors: productivity (labor productivity LP, capital productivity CP), activity (TT), and profitability (net profit rate NI, operating profit ratio OI) through the factor analysis method, and analyzed the impact of each factor on the stock return through steps 1 to 3. Findings - The regression analysis shows that productivity has a significant positive effect on the stock return through the full mediating effect of profitability and activity. Research implications or Originality - In a situation where the relationship between productivity and profitability is not clear, this study is meaningful in that it has empirically analyzed that productivity has a positive effect on the stock return by mediating effects of profitability and activity.

In knowledge information society entering global unlimited competition era, our middle and small sized companies are the base of national and enterprise competitiveness and core base of national economy as an origin of jobs. The competitiveness of middle and small sized companies is so important to decide the level of the competitiveness of the whole industries, but the gap from big sized company is much low in comparison with advanced countries from angles of important factors of enterprise growth, productivity and technological competitiveness, so, it's urgent to improve the competitiveness through productivity enhancement. The purpose of this research is to do a positive study on effects of learning organization management outcomes of middle and small sized company on enterprise productivity among various types of outcome brought for strengthening of enterprise competitiveness. It confirmed learning organization has functions and usefulness as a management tool bringing positive effects on enterprise productivity through the Productivity improvement.

Organizations use multiple team membership to enhance individual and team productivity and learning, but this structure creates competing pressures on attention and information, which make in difficult to increase both productivity and learning. My model describes how the number and variety of multiple team memberships drive different mechanisms, yielding distinct effects.

This paper examines the effects of major funding projects for graduate education in Korea, specifically the BK21 and the WCU programs, on the research productivity of professors and young researchers. We apply the standard DID method, which compares the increase in research outputs as measured by papers per year between groups before and during the project period. The DID estimates show that the effects are quite different for different fields, but they mostly indicate that the BK21 project is more effective in terms of the research productivity of the participating professors, especially those who study science and engineering areas. With regard to the productivity of graduate students, the results show that there was an increase in the research productivity of locally educated Korean doctoral degree holders after the graduate funding programs, mainly in natural science and engineering fields.
