본 연구는 우리나라 서비스화의 특징을 분석하기 위하여 서비스화에 대한 유력한 설명인 수요편향가설 및 Baumol가설을 우리나라 경험과 비교하였다. 이를 위하여 Baumol의 모형을 확장하여 패널 GMM방식으로 고용함수를 추정하였다. 분석결과를 요약하면 다음과 같다. 첫째, Clark의 수요편향가설을 살펴보기 위하여 1인당 GDP 증가와 서비스고용간의 상관관계를 살펴본 결과 서비스화에 있어 소득증가가 절대적인 역할을 수행한다는 Clark의 수요편향가설을 우리나라의 경우에도 확인할 수 있었다. 둘째, 서비스화에 있어서 생산성격차를 강조하는 Baumol의 가설은 도소매, 음식 및 숙박서비스를 제외하고 모든 서비스분류에서 확인할 수 있었다. 즉 제조업과 각 서비스산업의 노동생산 성격차가 확대될수록 서비스업의 고용이 증가한다는 사실을 우리나라의 경우에도 확인할 수 있었다. Using a panel data of Korea for 1979~2002, this study investigates the determinants of the service sector employment share in Korea. In order to analyze the impact of macroeconomic factors on the service sector's employment share we estimate a simple panel model which is in line with Baumol's model. The panel GMM estimation results show that: 1) The increase in the share of service-related jobs in total employment tends to rise with GDP per capita, which confirms demand-bias hypothesis proposed by Clark. 2) We find that a crucial role in this process has been played by the productivity gap. As Baumol's hypothesis or Baumol's disease, the expansion of the employment share in services relative to industry is the direct consequence of services' lower productivity performances.

서환주(Hwan Joo Seo) 한국IT서비스학회 2009 한국IT서비스학회지 Vol.8 No.2

Our study aims to investigate the determinants of international competitiveness and international competitiveness and international specialization in services, using OECD service trade data, Real exchange rates, world demand, economies of scale, diffusion of IT, human capital, R&D expenditure and institutional variables are introduced as explanatory variables in regressions for 29 OECD countries over 1996~2003. Some of major findings from the study can be summarized as follows, economies of scale play important role in transport and business services. Second. the index of freedom to trade measured by Faster Institute has a positive and significant impact on international competitiveness in telecommunication, finance and insurance and business services. Third, IT provides favorable condition to build international competitiveness in finance and insurance and business services. Fourth, R&D expenditure contributes to the amelioration of international competitiveness in transport services, while investment in new equipments contributes to increasing the competitiveness in telecommunication services. Thus, our results show the importance of the industrial base for developing a competitive service economy.

The objectives of this paper are to analyse the R&D investment efficiency gap between SME(Small & Medium Enterprises) and large firms in Korean industries. We mobilise the production function framework using the cross section and pooling data for this analysis. The results are as follows. First, the R&D expenditure gap and efficiency gap between SME and large firms are widened during the 90s. Second, using the production function analysis, we find positive correlation between R&D intensity and R&D investment efficiency, which is more prominent in the electronic industries. Third, the estimation results show that the additional 1% increase of SME`s R&D intensity will allow to reduce the 0.997% of efficiency gap between SME and large firms. Considering these estimation results, more investment to R&D by SME will reduce the efficiency gap in the future.

서비스 개념을 둘러싼 최근논의에 대한 비판적 고찰

Our Study aims to examine, from a critical perspective, recent approaches to the definition of services. Studies that deal with the question of how to characterize services offer three types of response. The first approach developed by classical economists proposes to use technical criteria (immateriality, non-separability between consumption and production, non-storage, heterogeneity) as foundation for a specific definition of services. The second, which is today most widely cited definition, that of Peter Hill proposes an institutional or a relation-oriented definition which emphasizes service triangle. Finally, the work of Gadrey, which investigates the impact of new technologies on service activities, offers a new general definition of services that is compatible with the existence of several demand rationales.

As the size and significance of financial market and financial institutions increased after the 1980s in advanced countries, there have been various discussions concerning the cause of the increasing role of finance in the modern economy, its economic effect as well as its measurement (Epstein, 2005). As Krippner (2005) pointed out, researchers are using the term ``financialization`` to cover various phenomena that are interrelated but relatively independent. After the financial crisis, Korean firms have been displaying a few patterns different from those before the financial crisis. The maximization of shareholder values as a mode of corporate governance has put pressure on managers to be interested in short-term performance and to shift management objectives from ``retain and reinvest`` to ``downsize and distribute`` An analysis of the management performance of the top 10 firms (excluding banking, insurance, and public enterprises) based on firms` assets shows that although firms have increased investment in financial assets, real investment in tangible and intangible assets decreased or displayed a weak increasing trend. Our study aims to analyze the relationship between finanicalization and slowdown of Korean firms` investment. Firstly, we investigate and categorize diverse definitions about financialization. Second, panel analysis over the 2000~2007 period supports the negative effect of financialization on accumulation in the Korean manufacturing industries. However, the causal relationship between financialization and slowdown of accumulation is not founded in Korean services.

Using I-O tables and outsourcing index developed by Campa and Goldberg (1997) and Strauss-Kahn (2003), this study estimates R&D outsourcing indexes and investigates the contribution of R&D outsourcing to the growth of TFP (Total Factor Productivity) in Korean manufacturing industries. The empirical results are summarized as follows. First, R&D outsourcing increases for the period 1995~2006. However, the growth rate is much slower than outsourcing to other service industries. Second, production cost and R&D outsourcing show inverted U-shaped relationship. This result shows that R&D outsourcing contributes to the growth of TFP only after it pass a certain critical scale. Third, the contributions of R&D outsourcing to the growth of TFP increase after the financial crisis. Fourth, the contribution of R&D outsourcing to the growth of TFP is positively and significantly related with the intensity of R&D outsourcing.

This paper analyzes the role of structural factors such as globalization, informatization and financialization in explaining the movement of earnings inequality in OECD countries over 1995~2005. The empirical analysis yields three main results. First, a majority of OECD countries experienced increase in earnings equality when we measure the inequality using the ratios such as (90th/10th) ratio, (90th/50th) ratio and (50th/10th) ratio. Earnings inequality since 1995 has occurred in the top half of the earnings distribution. Second, the estimation results show that globalization and informatization have a significant impact on the evolution of earnings inequality as proposed by previous studies. We find also the pivot role of financialization or the share holder value orientation in explaining cross-country differences and trends in earnings inequality. Third, the causes of earning inequality are different depending on percentiles.

By influencing the incentives to innovate, the strengthening of patents may affect economic growth in important way. An important question for many countries is whether patent law reforms induce more innovation. This paper examines the role of patents in innovation, utilizing Korean data on patent applications, expenditure of R&D, sales and concentration ratio. The evidence suggests that the strengthening of patents was a significant determinant of innovation in Korea. However, in our estimations, we do not completely eliminate the effects of other macro shocks. Therefore, we interpretate our results as representing an upper bound of Korean firms` responses to patent law reforms.

Globalization has undergone qualitative changes since the global financial crisis. Discussions are taking place in various aspects, ranging from discussions on whether these changes are structural changes or temporary adjustments to discussions on the causes of the trends toward deglobalization. This study aims to analyze deglobalization in terms of qualitative changes in the international regime. Furthermore, through modeling, we aim to typify the relationship between the hegemonic state and the rival country(country that seeks to overtake hegemonic country economically or militarily) from the Cold War to the present and analyze the relationship between these two countries not only in terms of economic relations but also in terms of security (military and economic security). In addition, based on geoeconomic discussions, we will examine how the weaponized interdependence affects the economy. Based on this analysis, we have described several scenarios for the future path of US-China relations.
