In this study, we consider infinite supply of raw materials and backlogged demands as given two boundary conditions. And we need not make any specific assumptions about the inter-arrival of external demand and service time distributions. We propose a numeric model and an algorithm in order to compute the first two moments of inter-departure process. Entropy enables us to examine the convergence of this process and to derive measurable relations of this process. Also, lower bound on the variance of inter-departure process plays an important role in proving the existence and uniqueness of an optimal solution for a numeric model and deriving the convergence order of augmented Lagrange multipliers method applied to a numeric model. Through these works, we confirm some structural properties and numeric examples how the validity and applicability of our study.

1978년 개혁 개방 이후, 중국은 해외 자본에 대한 의존도가 높은 '외생적 발전 전략'을 추진하였으나, 2000년 이후부터는 과학 기술 및 혁신 역량 강화에 초점을 둔 '내생적 발전 전략'을 추진하였다. 이제 중국에서의 기업 경영 활동은 선진 기술 및 경영 기법 이전을 촉진하는 새로운 제도와 조응하면서 차별적인 기업 혁신 네트워크를 형성하고 있다. 그 결과, 공간 경제의 성격은 초기 '수출 지향적 발전 공간'에서 '기술 지향적 발전 공간'으로 변화되었다. 이러한 맥락에서 본 논문은 중국 후기 사회주의 체제전환의 대표적 사례 공간인 상하이에 입지한 한국 투자 기업의 혁신 네트워크 특성을 기업내, 기업 간, 기업 외 관계 측면에서 분석함으로써, '기술 지향적 발전 공간'의 성격을 규명하고자 한다. 한국 투자 기업의 기업 내 관계에서는 사적 네트워크를 공적 네트워크로 전환함으로써 혁신 창출의 가능성과 경영 효율성을 극대화하려는 기업의 전략을 확인할 수 있었다. 기업 간 관계에서는 기업 규모, 산업 부문, 투자 유형 등에 따라서 차별적인 네트워크 특성을 보여주었다. 기업 외 관계는 외형적으로 제도적 개입 수준이 높은 공적 네트워크가 나타나고 있지만, 내면적으로는 ��시 관계(關係)에 기반을 둔 사적 네트워크가 나타났다. 결론적으로 중국 상하이의 공간적 특성은 외형적으로 '신 구제도 간의 상호작용과 구사회주의 체제 네트워크의 재구조화' 형태를 띠는 한편, 내면적으로 '신제도의 차단에 따른 구사회주의 체제 네트워크의 지속' 형태를 띠고 있어 '착근적' 성격과 '과잉 착근적' 성격이 함께 나타나고 있다.

This research examines the effect of the relatedness and the gap between Resources and mechanisms on effectiveness of inter-organizational knowledge transfer. According to the literature, there has been a competing theory between two claims; one is that inter-organizational knowledge transfer will be more effective due to the reduction of the transaction cost as the relatedness increases. And the other is that the mutual complementarity of different organizational characteristics will increase synergy. In total, the relatedness and the gap of the Resource and mechanism makes the inverted U-shaped relationship with the inter-organizational knowledge transfer. As the result of empirical analysis about 109 Korean-based Joint Ventures entered country, it shows that the relatedness of parent company's production Resources, learning mechanisms, and coordination mechanisms made the inverted U-shaped relations with the inter-organizational knowledge transfer and the gap of production Resources and adjustment mechanism formed the same relationship. However, the U-shaped relationship has been established in the relatedness of market Resources, but the gap of market Resources and the learning mechanism was not statistically significant. Through this study, I can draw a best conclusion that the inter-organizational knowledge transfer will be more effective when the relatedness and the gap of management resources and mechanisms is in optimal level. However, when it comes to market Resources, it can be inferred that the result could be the opposite because the partner country's market environment would be different.

This study proposes the accurate economic effect (employment inducement coefficient, hiring inducement coefficient, index of the sensitivity of dispersion, index of the power of dispersion, and ratio of value added) of Korea software industry by analyzing the inter-industry relation using the modified inter-industry table. Some previous studies related to the inter-industry analysis were reviewed and the key problems were identified. First, in the current inter-industry table publishedby the Bank of Korea, the output of software industry includes not only the output of pure software industry (package software and IT services) but also the output of non-software industry due to the misclassification of the industry. This causes the output to become bigger than the actual output of the software industry. Second, during rewriting the inter-industry table, the output is changing. The inter-industry table is the table in the form of rows and columns, which records the transactions of goods and services among industries which are required to continue the activities of each industry. Accordingly, if only an output of a specific industry is changed, the reliability of the table would be degraded because the table is prepared based on the relations with other industries. This possibly causes the economic effect coefficient to degrade reliability, over or under estimated. This study tries to correct these problems to get the more accurate economic effect of the software industry. First, to get the output of the pure software section only, the data from the Korea Electronics Association(KEA) was used in the inter-industry table. Second, to prevent the difference in the outputs during rewriting the inter-industry table, the difference between the output in the current inter-industry table and the output from KEA data was identified and then it was defined as the non-software section output for the analysis. The following results were obtained: The pure software section's economic effect coefficient was lower than the coefficient of non-software section. It comes from differenceof data to Bank of Korea and KEA. This study hasa signification from accurate economic effect of Korea software industry.

The resumption of economic cooperation between South and the North Korea will be a new growth engine for our economy. Many Korean companies are preparing to invest in North Korea in accordance with the progress of inter-Korean relations. However, there are many risks inherent in inter-Korean economic cooperation, as experienced in previous cases. Specifically, one should be prepared for unfair measures such as the expropriation of investment assets of South Korean enterprises by North Korea authorities. Therefore, it is essential to review the protection measures of investment in North Korea and to review the investment dispute settlement system. The South and the North have an agreement to establish the inter-Korean Commercial Arbitration Committee to resolve the disputes that may arise if one party's investments are lost due to inappropriate or unfair measures due to the other party's authority. However, the Investment Agreement, which governs the Inter-Korean Commercial Arbitration Committee, contains a number of declarative statements that are somewhat ineffective. Even today, nearly 20 years after the adoption of the Agreement, the specific detailed procedures have shown no real progress, such as in the enactment of arbitration rules. Therefore, at present, it is difficult to expect a system that can effectively address the damage of our corporations which have invested in North Korea. When the assets freeze after the suspension of Kumgang tourism and the closure of the Kaeseung Industrial Complex by North Korea, the activation of the inter-Korean Commercial Arbitration Committee is the most important prerequisite for economic cooperation with North Korea. For this purpose, the resolution of disputes through the Inter-Korean Commercial Arbitration Committee has to be made more concrete, with the effectiveness of the dispute settlement system enhanced by means of various efforts.

The purpose of this research is to introduce the concept of "relationship formation factors" in inter-firm relations and to empirically demonstrate that they are effective in improving the relationship results by means of anmediating variable. Therefore, the basic model of this study consists of the independent, mediating, and dependent variables. First, the independent variable, that is, the relationship formation factors, is further classified into three components： transactional, relational, environmental characteristics. Then, the study empirically examines how each of the three components influences the dependent variable, that is, the business performance(Load Factor), by way of the mediating variables, that is, trust and relationship commitment.

Purpose: The purpose of this study is to analyze the economic ripple effect(ERE) of logistics industry by construction of Trans-Korea Railway (TKR) and present policy measures to minimize the economic loss of South Korea (SK). Research design, data and methodology: As the analysis method, exponential smoothing was used for demand forecasting, Input-Output analysis was used to estimate the economic ripple effect coefficient, and scenario analysis was used to an efficient way to invest in TKR to minimize SK's economic losses. Results: 1) the production(logistics fares) of TKR for 10 years after its completion is about 11.42 trillion won in positive relations, and 26.89 billion won in negative relations. 2) the ERE of SK in positive relations is 24.32 trillion won in production inducement effect, 8.1 trillion won in value-added inducement effect, 3.54 trillion won in import inducement effect, and 70,930 persons in employment inducement effect. But the ERE was insufficient in the negative relations. 3) SK's efficient investment method is providing materials and equipment by SK and building the TKR by North Korea in positive inter-Korea relations. Conclusions: For the successful operation of TKR, international cooperation, legalization and stable peace settlement on the Korean Peninsula are required.
