Abstract
In case of a shortage of China’s domestic timber, the research of China’s timber security has become increasingly more important. Using the pressure-state–response (PSR) conceptual model and the entropy method, the timber security of China during 1997–2017 was evaluated and analyzed to understand and master the situation of timber security in this paper. The results showed that: (1) The pressure of timber security in China during 1997–2017 was increasing in waves, with the condition of timber imports as the main factor; (2) the state of timber security in China presented a downward-then-upward tendency during 1997–2017, the main influencing factors of which were the domestic timber supply and forest resources condition; (3) responses to ensure the timber security of China almost indicated a steep rising trend, because both the timber industry technical progress index and the waste paper recovery rate improved the safety of timber in China; and (4) the changing trend of the comprehensive evaluation of timber security in China approximately agrees with that of the state evaluation, which showed that state indicators were key factors affecting the timber security of China. The pressures influencing the timber security of China are rising, while the state of timber security and the responses of the high-tech industry have been improving at a higher range than the pressures, which has led to an improvement of China’s timber security.
Highlights
Compared with other traditional raw materials, timber is renewable and low emission, has relative low energy consumption in processing, and is widely used in construction and decoration engineering
The supply state accounts for the largest weight followed by the resource and environment state factor, and the industry factor takes the smallest weight; that the weight of the positive indicator is much greater than that of the reverse indicator indicates that the current level of timber security in China is relatively optimistic
In this research, based on the PSR model, and on the basis of following the principles of scientificity, In this research, based comparability, on the PSR model, and on the of following the principles of globality, representativeness, and operability, a setbasis of China’s timber security evaluation scientificity, representativeness, comparability, and operability, set was of China’s timber index systemglobality, was constructed, and China’s timber security level from 1997 toa2017 evaluated and security evaluation index system was constructed, and security level from to its changing trend was analyzed by weighting the indictors objectively using the entropy method and wasthe evaluated and itslinear changing trend method
Summary
Compared with other traditional raw materials (steel, cement, and plastic), timber is renewable and low emission, has relative low energy consumption in processing, and is widely used in construction and decoration engineering. It is the raw material of timber products, such as wood-based panels, furniture, paper, and paper products. China has a prominent structural contradiction between the domestic timber supply and demand, in that the supply of large-diameter timber is insufficient, low-end products have excess capacity, and famous and high-quality products rely mainly on imports.
