Research on Trade Competitiveness of Forest Products in Jiangsu Province Based on Principal Component Analysis Method

林产品贸易竞争力水平的定量分析是推动林产品行业高质量发展的基础。基于2020年全国31个省市的林产品贸易相关统计数据,从原料资源、人力资本、市场状况、宏观经济环境、技术创新、风险防范六个方面构建科学合理的林产品贸易竞争力水平评价体系,运用主成分分析和聚类分析方法,对江苏省林产品贸易水平进行客观评价。研究表明:江苏省林产品贸易水平位于全国林产品贸易竞争力的高水平区,在技术创新等方面领先其他省市,但在林业资源等方面具有明显劣势,并据此提出相应的对策与建议。

The quantitative analysis of the competitiveness level of forest products trade is the basis for promoting the high-quality development of forest products industry.Based on the relevant statistics of forest product trade in 31 provinces and cities in China in 2020,this paper constructed a scientific and reasonable evaluation system for the trade competitiveness level of forest products from six aspects:raw material resources,human capital,market conditions,macroeconomic environment,technological innovation and risk prevention.Then it used principal component analysis and cluster analysis methods to objectively evaluate the trade level of forest products in Jiangsu Province.The results showed that the trade level of forest products in Jiangsu Province was located in the high-level area of national forest product trade competitiveness,and it was ahead of other provinces and cities in technological innovation,but it had obvious disadvantages in forestry resources,and it put forward the corresponding countermeasures and suggestions accordingly.
