With the rapid development of the timber industry, illegal logging of timber and its trade have become an important issue for world sustainable development. Many governmental and private sectors have taken measures to ensure the legality of wood, and wood legality verification is becoming more and more common. Chinese wood processing industries are mainly centralized in the region of Jiangsu and Zhejiang. In this paper, a questionnaire survey is used to investigate the status of legality verification of wood processing enterprises in Jiangsu and Zhejiang. The results show that applying for timber legality verification is conducive to the increase in enterprise benefits, but due to different levels of management and technology application rate, enterprises have deviations in their understanding of different legality certification systems. High certification costs and insufficient awareness of legality verification have become the main obstacles to applying for timber legality verification of wood processing enterprises in Jiangsu and Zhejiang. Based on this conclusion, this paper suggests some policies to promote the legality verification of Chinese wood processing enterprises.

Illegal logging has caused serious damage to the global forest environment. China, Japan, India and South Korea have been criticized for their imports of illegal timber. Based on a trade balance analysis method, this paper evaluates the imports of illegal timber of China, Japan, India and South Korea. The results show that China has serious illegal timber imports with the Republic of Congo, Ghana, Papua New Guinea, Laos, Brazil and Malaysia. India has serious illegal timber imports with Brazil and Papua New Guinea. Japan has serious illegal timber imports with the Republic of the Congo, Cameroon, Malaysia and Papua New Guinea. South Korea has serious illegal timber imports with Malaysia. In order to control the imports of illegal timber, there is a need to further strengthen international cooperation and domestic legislation, enhance the protection and cultivation of forest resources and reduce dependence on imported timber.
