| Summary: | 碩士 === 國立臺灣大學 === 森林環境暨資源學研究所 === 103 === Roundwood and sawnwood are the raw materials of lots of processed wood products based on the forest resource. The countries which are lack of forest resource might be the main demanders of the wood products. As a result, the first purpose of this paper is to figure out the demanders and to study the trade flow between countries in the World’s trade network. Social Network Analysis (SNA) is one of the method to carry out the quantitate measurement of a network and show the network in a graph. Centrality Analysis is the main application of SNA and applied to study the industrial roundwood and sawnwood importing trade network in 2000, 2005 and 2010 in this paper with NodeXL software. Then, observe the status of import of countries to determine the main importing countries for further study.
The countries with high in-degree centrality mean that they have a wide and huge connection with others. According to the results of the study, most of these countries are located in Europe and Asia, and China is the country with highest in-degree centrality and largest importing quantity of industrial round wood in 2010 among the world. Therefore, it is the country approaching the core of the network the nearest. In the part of sawn wood, USA used to be the main import among the global sawn wood trading network in 2000 and 2005, however, China becomes the one in 2010 with higher and growing in-degree centrality and more importing quantity.
Therefore, this thesis focuses on China in the following sections. In 1992-2013, Hong Kong plays the role as entrepot port between China and the World in the early 1990s. In the 2000s, the data discrepancies between China and its partners are suspected as illegal trade. With the growth of China’s economic development, China directly imports industrial roundwood and sawnwood from the main exporters and there is also suspected illegal timber trade among them, e.g. Papua New Guinea and Southern Asia for industrial round wood and Russia, Philippines and Thailand for sawnwood.
