국제통상 ; 중국의 지역별 수출과 경제성장의 인과관계 분석(1952-2004)
최성일 ( Sung Il Choi ) 국제지역학회 2008 국제지역연구 Vol.12 No.3
본 논문은 1952-2004년 걸쳐 중국의 수출과 경제성장 간의 인과관계를 지역별(동부, 중부, 서부), 시대별(개혁개방 전후)로 고찰해 본 것이다. 이를 위해 먼저 변수들의 안정성 여부를 검토하기 위해 단위근 검정을 실시했으며, 다음으로 변수간 장기적인 안정관계를 확인하기 위해 공적분 검정을 수행했고, 마지막으로 오차수정모형을 추정함으로써 그랜저 인과관계 검정을 실시했다. 분석결과 전체기간에서 동부지역은 수출이 경제성장에 유의한 영향을 미치는 것으로 나타났으며, 중서부지역에서는 그 정도가 약하게 나타났다. 동부지역의 경우 개방정책이 집중적으로 나타난 지역적 특성을 반영하여 개혁개방 이전에는 수출과 경제성장 간의 인과관계가 나타나지 않았으나, 개혁개방 이후에는 수출이 경제성장에 유의한 영향을 미치는 것으로 나타났다. 개혁개방을 전후하여 변화가 없을 것으로 예상했던 중서부 지역의 경우, 중부지역은 개혁개방 이전에는 무역과 경제성장 간에 인과관계가 보이지 않았으나 개혁개방 이후에는 양방향 인과관계가 강하게 나타났으며, 서부지역의 경우에는 오히려 개혁개방 이전에 무역이 경제성장에 유의한 영향을 미치는 것으로 나타난 반면 개혁개방 이후에는 반대로 경제성장이 무역에 유의한 영향을 미치는 것으로 나타났다. This paper aims to analyze the causal relationship between exports and regional economic growth based on the provincial data over the period from 1952 to 2004. To reflect the regional and chronical characteristics, this paper divides China into three regions; Eastern, Central and Western regions, and also the whole period into two sub-periods; before and after 1979 when the Open-door policy(ODP) was initiated and applies Granger causality analysis The Granger causality tests showed that exports Granger cause economic growth in the Eastern region, but not in the Central and Western regions, as a whole. When the period is divided, in the Eastern region, causal relation between the two variables was not found before the Open-door policy. For the second period, however it turns out that exports cause the region`s economic growth. This result is consent with the fact that the region has been a main beneficiary of the policy. For the Central region, the tests showed no causality in the pre-ODP period, but significant bidirectional causality in the post-ODP period. Meanwhile, in the Western region, exports turned out causing economic growth significantly before the ODP, while economic growth appeared to causing trade after the ODP.

Existing manufacturing system has consumed too much energy, space and resource in micro parts manufacturing. To improve this, micro factory system is suggested. But it is difficult to get the high reliability in the assembly, production and inspection of the minute parts because the construction of the micro factory has been started just before. In this study, we will build the digital manufacturing simulation on the micro factory's process and verify the production(lens module of mobile phone) and assembly process using this simulation.

Assembly is mentioned as important process saving time and cost where produce the machine with many parts relationships. In this study, parts assembly relationship is analysed for assembly information of micro milling machine. Liaison diagram, datum flow chain and assembly tree are discussed for a micro milling machine model which have been developing for research. We can find out the characteristics of micro machine assembly and discuss about more facility of assembly. We need a information about assembly characteristics. Some analysis in this paper about micro milling machine will give a useful tools for assembly. The 3D model of micro machine which is studied in this paper is not complete model. Main parts of a micro milling machine are used and presented.

Obturator hernia is a rare variety of pelvic hernia. The diagnosis frequently is delayed and may be accompanied by dehydration, acute abdominal distress and small bowel strangulation. We report a case of totally extraperitoneal repair of obturator hernia with partial intestinal obstruction. An eighty-two-year old female with intermittent abdominal pain was diagnosed with obturator hernia with partial intestinal obstruction. We did total extraperitoneal laparoscopic repair of the obturator hernia with polypropylene mesh. Total extraperitoneal laparoscopic repair for obturator hernia is a safe and effective treatment.
