“…The data in this paper comes from the China Timber and Wood Products Circulation Association and the National Bureau of Statistics. Referring to Guan and Zhang (2022), Tang and Song (2013), Wang and Tian (2013) and Zhang et al's (2018) studies, we take the increases in log import prices as grouping variables, use domestic timber market prices index (TPI), forest industry producers’ ex-factory prices index (PPI) and furniture retail price index (CPI) to represent the wood product market price, and take them as explanatory variables. Also, we take the real effective exchange rate of RMB, gross domestic product, domestic log import quantity, log import price of the previous period and world log export average as covariates in our breakpoint regression.…”

Russia is China's main log supplier and has implemented a series of log export control policies. The implementation of Russia's export control policy has inevitably had an impact on China's timber processing industry. This paper uses breakpoint regression to analyse the impact of the increase in the import price of logs under the Russian log export control policy on the market price of timber products in China. The results show that under the control policy, the increase in log import prices had a significant positive impact on the timber product market when April 2008, January 2010 and January 2019 were the breakpoints. Due to the lag effects in price transmission, the impact on China's timber product market was not reflected when July 2007 and January 2018 were the breakpoints. Based on the research conclusions, this paper puts forward some suggestions from the perspective of China's log supply security.

“…The increase in global population and changing lifestyles have increased the demand for wood-based panels (WBP), with global production of WBP more than doubling from about 178 million m 3 in 2000 to about 396 million m 3 in 2021 (FAO, 2023). On the other hand, competition for raw wood supply has intensi ed, leading to an increase in wood prices, mainly due to increased demand for raw wood from both WBP producers and the bioenergy sector (Guan and Zhang, 2023). In countries like Iran, the wood supply is much worse due to the tripling of production volume in the last decade (more than 3 million m 3 ) and ongoing forest conservation plans (Heidarlou et al, 2023).…”

ABSTRAC In this study, the properties of particleboard made from wheat straw using citric acid (CA) as a bio-adhesive were investigated. The effects of mat moisture content (MC) and adhesive on mechanical properties (flexural strength, modulus of elasticity, internal strength) and physical properties (thickness shrinkage and water absorption) of straw particleboard were evaluated. To control the MC of the mat, the resinated straw particles were oven dried at different times (2 to 14 hours) and temperatures (80 and 100 °C) to obtain a mat with MC between 20 and 0.5%. The effects of an adhesive content of 15, 20, 25 and 30% (based on the dry mass of the straw) on the properties of the panels were also studied. The best MC of the mat before hot pressing was about 11% (drying of the particles in 2 hours at 100 °C), and the corresponding board had the highest mechanical and the lowest physical properties. Further decreasing the MC of the mat from about 11% to 0.5% had a negative effect on the mechanical and physical properties of the straw particleboard. Increasing the adhesive content from 15% to 30% improved all mechanical and physical properties of the panels; however, the changes in the range of 20% to 30% of adhesive content on the flexural properties and water absorption were not significant. In general, the results showed that due to the acidic nature of CA, it is possible to produce particleboard from wheat straw without pretreating the straw particles before use.
