This paper examines relative contributions of extensive margin and intensive margin of Korean exports growth to China after 1990s', based on an analytical approach proposed by the Hummels and Klenow(2005). In this paper, extensive margin is defined as a weighted count of Korean exports categories relative to the rest of world's export categories to China. On the other hand, intensive margin refers to Korean exports to China relative to the rest of the world's exports to China, exclusively in those product categories that Korea exports to China. According to the results of the analysis, the expansion of Korean exports to China was induced mainly by the increase of intensive margin. This result is consistent with $Besede{\check{s}}$ and Prusa(2007) as well as the Helpman, Melitz and Rubinstein(2007) who suggest that intensive margin is a more important factor than extensive margin for sustaining growth of export in the long term. In addition, this paper shows that the survival rates of exports of parts and components and capital goods is relatively higher in comparison to those of primary and consumption goods. This implies that the expansion of international division of labor under the global production network could substantially affect the survival of exports.

The purpose of this research is to analyze the impact of business scope and technological innovation capability(TIC) on firm performance in SMEs. Among the 1,077 SME sample data collected with the help of Korean Industrial Complex Corporation, 228 sample data from capital goods sectors had been selected and analyzed. Several mutiple regression models were developed to test the main and the interaction effects of two independent variables business scope and TIC on SME performance. The empirical analysis show that the number of product lines, one of the two scope variable measured, is positively correlated with the return on sales(ROS). Among the variable of TIC, the number of intellectual property rights(IPRs) is positively correlated with the sales growth rates of SMEs, which the ratio of engineers to total employees is positively correlated with the ROS of SMEs. The results also delineated some interaction effects of business scope and TIC on SME performance. There exists a positive interaction effect of the ratio of engineers to total employees and the number of product lines both on ROS and scales growth rate. The interaction of the number of customers and the number of IPRs positively effects on ROS, and also the interaction of the number of product lines and the number of IPRs are positively related with ROS. Findings of this research indicates that it is necessary for SMEs in capital goods sectors to accumulate technological innovation capability and to expand business scope to improve firm performance. Furthermore, the accumulation of internal TIC should accommodate with the expansion of business scope to gain an improved performance. Particularly, adequate technological innovation capability is required to address the need of expanded customers when enlarging the scope of customers.

최근 무역흑자기조가 유지되고 있으며 2003년 이후 수출증가율이 수입증가율을 앞서나가고 있어 무역 흑자 규모가 2004년 약 200억불로 커지고 있다. 그러나 주요기간산업의 대일의존은 여전하다. 특히 광학산업을 포함한 기계산업은 역조규모가 가장 크며 대부분의 품목들이 대일수입에 의존하고 있고 그 뒤를 전자전기산업이 따르고 있다. 이처럼 한국의 자본재 산업은 해외에 의존하고 가공/조립을 통한 범용제품(후방산업) 양산에 치우쳐왔다. 따라서 기술개발능력이 있는 중소기업의 원천기술에의 도전을 적극적으로 지원하는 연구개발 사업이 필요하며, 기업이 보유한 특허와 같은 지적재산에 투자하는 지적재산캐피탈(IPC)을 도입하여 기술보유기업의 성장과 신기술의 시장진입을 도와야 할 것이다.

This paper empirically examines how capital structure inertia varies across industries and there is different in industries, and whether this fact is explained by product market competition using non-financial firms listed in KOSP market over periods of 1981 to 2015. In empirical test, I find that firms with more competition environment tend to have inertia behavior in making decision of capital structure. This implies that it is explained by debt discipline effect and it is substitution for product market competitions. Also I find that manager tends to take action actively making decision of capital structure when product market competition is low. Also I show that they use debt to constraint the free cash flow. As a result, I conclude that Korean non-financial firms do not have more strong inertia behavior in capital structure rather than U.S. firms. Second, using OLS estimation, inertia effect disappears while there is strong inertia effect in relationship between inertia and product market competition. This result suggests that transaction cost is not key factor in explaining inertia behavior of capital structure.

This study examines the effect of firms' working capital management on their performance for a sample of non-financial companies listed on the Korea Exchange (KRX). The working capital and corporate performance are measured as the ratio of the net working capital to sales and return on assets, respectively. The results are as follows. First, there is no significant relationship between the working capital and corporate performance in the total sample. Second, the working capital is positively related to the firms' performance in the negative working capital group while the working capital is negatively related to the corporate performance in the positive working capital group. These findings indicate the existence of an optimal working capital level for firms. Third, the firms' financial constraints have no effects on the relationship between the working capital and corporate performance. This suggests that there are no interactive effects among the working capital, financial constraints, and profitability of the firms. This study implicates that managers should consider the different roles and impacts when developing an efficient working capital management strategy.
