⑴ Background——Green credit is the main part of China’s green finance system. The interaction between green credit and technology innovation is an important driving force for the transformation and upgrading of the forestry industry structure, and also an important means to realize the high-quality development of modern forestry. To discuss the specific effects of green credit and technology innovation on China’s forestry industry structure can provide a theoretical basis for the high-quality development of modern forestry. ⑵ Methods——This paper proposes the research hypotheses by analyzing the potential impact mechanism of green credit (hpc) and forestry technology innovation (tepscore) on the forestry industry structure (nfishc). Based on the panel data of 28 provinces (municipalities and autonomous regions) from 2008 to 2019,the static FGLS fixed effects model of C-D production function is used to explore the interaction effects of green credit and technology innovation on the forestry industry structure. Meanwhile, in order to solve the possible endogeneity problem of the model and analyze the influence of interaction terms on the interrelation between green credit and technology innovation, the lagged terms of the explained variables are added and the dynamic system GMM model is used to estimate the interaction of green credit and technology innovation on the forestry industry structure. ⑶ Results——Firstly, green credit and forestry technology innovation both play a significant role in promoting the forestry industry structure. Among them, every 1% increase in the level of green credit will increase the forestry industry structure by 0. 126%,every 1% increase in the level of forestry technology innovation will increase the forestry industry structure by 0. 114%. Secondly, the interaction between green credit and forestry technology innovation can indeed enhance their effects of promoting the optimization of forestry industry structure, what’s more, green credit and forestry technology innovation are threshold variables to each other and both of them have a single threshold effect on forestry industry structure. In particular, when the proportion of high energy-consuming interest expenditure is less than 3. 914,there will be a certain scale effect and agglomeration effect. Every 1% increase in the level of forestry technology innovation, the forestry industry structure will significantly increase by 0. 249%. However, when the effect of interaction terms on green credit and forestry technology innovation is further examined, it is found that the development of green credit is not conducive to forestry technology innovation and forestry technology innovation also has a significant negative impact on green credit. Finally, the analysis of the effect of control variables on the forestry industry structure shows that in the process of forestry production, only increasing labor input (fen) has a little effect on the forestry industry, and the effect is not significant. Excessive financial intervention (finf) is not conducive to the transformation of forestry structure. Urbanization level (urban), opening degree (op) and forest coverage rate (fcr) may not only promote the consumption and trade of the forest products, but also adversely affect the forestry industry economy. ⑷ Conclusions and Discussions——First, constantly optimize the investment environment of green credit and give full play to the role of financial regulatory departments in guiding and encouraging banks to develop green credit. Banks should actively implement green credit policies, taking credit scale, structures and efficiency into accounts to lead the development of forestry green enterprises. Second, based on the development status of forestry enterprises, continue to increase the cultivation of the innovative subjects, improve the level of human capital in forestry, promote the upgrading of forestry industry structure. Third, increase the investment in forestry research and development and education of forestry talents, improve the conversion rate of forestry technology patents, and pay attention to the deep integration of forestry technology innovation and forestry green credit to realize the high-quality development of forestry economy.
