摘要: [目的]随着中国成为世界第一大木材进口国和第二大木材消耗国,大量依赖木材进口对中国林业产业安全日益形成威胁,更被指责为"毁林"的罪魁祸首和"世界森林资源的黑洞";而作为木质林产品出口大国,对国际市场的严重依赖也蕴藏着越来越大的风险。目前中国木质林产品外贸依存度尚没有统一的定义、计算方法和口径,现有测算结果差异很大,直接影响到对中国木质林产品外贸依存程度的正确判断,进而影响到相关贸易、产业政策的制定,迫切需要明确定义、制定科学的算法。[方法]分析现有中国木质林产品外贸依存度研究中的各种定义、算法、研究角度、使用目的、统计口径和数据来源,研究其存在的问题,总结不同算法反映的信息、适用范围和数据要求。利用改进的算法,使用中国林业统计数据,测算中国木质林产品外贸依存度水平和变化趋势;使用联合国粮食及农业组织数据,测算并比较评价世界主要林产品进口国木质林产品外贸依存度水平。[结果]提出考虑林业产业总产值中产业构成的传统价值量算法的修订算法,基于该算法的测算结果显示,2014年中国木质林产品进口依存度和出口依存度分别为12.59%和14.51%,并不高;明确原木折算法在木材资源供给进口依存度测算中的应用,提出木材消费净进口依存度及其算法,讨论是否计算废纸问题,确定原木折算法使用的原木当量系数、在纵向和横向比较中应使用的林产品统计口径范围和数据来源,基于该算法的测算结果显示,2002—2014年中国木材资源供给进口依存度和木材消费净进口依存度均呈先下降再上升的趋势,2014年分别为47.94%和35.85%,与世界主要林产品进口国相比均处于中等水平;提出产品数量法适用于计算某些林产品的生产出口依存度和消费进口依存度,确定其具体算法,对刨花板等中国主要木质林产品的测算结果表明,几种林产品生产的出口依存度均在8%以下,但胶合板尤其是纸和纸板的出口贸易安全还有必要加以持续关注,几种林产品的消费进口依存度很低,均在3%以下,但刨花板、纸和纸板消费对进口依赖程度相对较高,可以进一步提高产品质量和档次以实现进口替代。[结论]在中国木质林产品外贸依存度的测算上,不同算法反映不同的信息,有不同的适用范围和不同的数据要求,在使用时要针对实际研究问题和具体用途谨慎选择。总体上,中国木质林产品的外贸依存度处在一个相对安全、合理的变化范围内,尚没有对林业产业安全形成实际威胁。

Abstract: [Objective] With China becoming the largest country of wood importing and the second largest country of wood consumption in world, the highly dependent on timber imports, has threatened increasingly China's forestry industry security, and China is often accused of the criminal chieftains of "deforestation" and "the black hole" of the world's forest resources. As a big exporter of wooden forest products, there is also a growing risk for serious dependence on the international market. Despite being concerned by many scholars, but at present, there is no unified definition, measuring method and statistical caliber about the foreign trade dependence of China's wooden forest products, and the existing calculation result are very different. All of these have a direct impact on the correct judgment of the degree of dependence on foreign trade of China's wooden forest products, and thus affect the formulation of relevant trade and industrial policies. It is urgent to define the concept and to make a scientific measuring method.[Method] This paper analyzes various definitions, measuring methods, research perspective and purpose, statistical caliber, data sources and existing problems of the dependence on foreign trade in existing researches, and also summarizes the reflected information, the scope of application and the data requirements of different measuring methods. Using the improved measuring method, based on the Chinese forestry statistics, this paper calculates the degrees of the dependence on foreign trade of China's wooden forest products, and makes a longitudinal comparison. Using the data of food and agriculture organization(FAO), this paper calculates and compares the degrees of the dependence on foreign trade of wooden forest products, in major trading countries of wooden forest products.[Result] This paper puts forward a revised value method about the traditional measuring method, which takes into account the industrial structure of the gross output value of forestry industry. Using this revised traditional measuring method, the calculation result show that China's dependence on imports was 12.59% and China's dependence on exports was 14.51% in 2014, all of them were not high. This paper makes clear the application of the log conversion method in the calculation of the import dependence of timber resources supply, proposes the net import dependence of timber consumption and its measuring method, and discusses the problem of recovered paper, defines the log conversion coefficient, the statistical caliber and the data sources in the longitudinal and horizontal comparison. Using the log conversion method, the calculation result show that China's import dependence of timber resources supply were 47.94% and China's net import dependence of timber consumption were 35.85% in 2014, both of them showed the first declining and then rising trend from 2002 to 2014, and were at the medium level compared with the world's major forest products importing countries. The product quantity method should be applied to calculate the production export dependence and the consumption import dependence of certain forest products, this paper illustrates their specific measuring methods. The result of the calculation of China's main woody forest products, show that the production export dependence of these forest products are all below 8%, but it is necessary to pay attention to the export trade security of plywood, especially paper and paperboard, and the consumption import dependences of these forest products are very low, all below 3%, however, the consumption import dependences of particleboard and paper and paperboard were higher, China should further improve their quality and grade to achieve import substitution.[Conclusion] In the calculation of dependence on foreign trade of China's wooden forest products, different measuring methods reflect different information, and have different application scope and different data requirements, so the measuring method should be careful selected, according to the actual research questions and the specific use. On the whole, the dependence on foreign trade of China's wooden forest products was in a relatively security and reasonable range, and they had not formed a real threat to the forestry industry security.
