本研究應用Jepma(1986)所提出的二階層固定市場佔有率(Constant Market Share, CMS)模型,分析2002年至2013年緬甸原木在台灣原木進口市場的競爭力,以台灣原木來源國11國為分析比較對象,依照行政院農業委員會的原木「4010101針葉樹原木」和「4010101闊葉樹原木」的進口數據進行實證研究。 實證結果顯示隨著緬甸原木對台灣的出口成長,其在台灣的競爭力也隨之成長。緬甸原木在台灣的競爭力主要來自CMS模型的一般競爭力效果、特定競爭力效果和動態結構殘差效果,其中一般競爭力效果最為顯著。非法原木出口也是促進緬甸原木出口成長的主要原因之一,非法原木出口已造成緬甸森林涵蓋率大幅下降,唯有政府盡速提出有效因應措施,才能確保緬甸林業永續發展。
This study, exploiting CMS model, analyzes the export competitiveness of Myanmar's logs from the year 2002 to the year 2013 in Taiwan with the 11 countries as the study object. The research data was obtained from the database of Council of Agriculture, Executive Yuan according to which logs, in this study, are classified as [4010101 conifer log] and [4010101 broadleaf log] in the study. The finding indicates that export competitiveness of Myanmar’s logs in Taiwan market mainly resulted from pure residual, static structural residual and dynamic structural residual of the CMS model, with pure residual being the most significant. Due to illegal logs exportation being so common in Myanmar, which is one of the main reasons of promoting Myanmar’s logs exports growth and illegally logging resulted in a substantial decline in the rate of forest coverage in Myanmar. Myanmar government, in light of this, should promptly enact some effective response measures to ensure the sustainable development of forestry industry in Myanmar.
