【摘要】 以林业投资对经济增长的影响作为研究对象,选取31个省区市2005—2018年面板数据作为样本,运用普通最小二乘法、固定效应模型、随机效应模型、系统广义矩估计模型等,分析林业投资与经济增长之间的关系。结果表明:林业投资对经济增长呈一定的正向影响;林业投资对经济增长的正向影响具有区域异质性,东部和中部地区较为显著,西部地区不显著;林业投资与经济增长之间存在一定的"倒U型"的非线性关系。依据研究结果,提出三点政策建议:适当增加林业投资、适度提高林业投资效率、适时调整林业投资的范围。更多还原

【Abstract】 Taking the impact of forestry investment on economic growth as research object, we selected panel data of 31 provinces from 2005 to 2018 as samples, and used Ordinary Least Square method, Fixed Effect model, Random Effect model and System GMM model to test the linear and non-linear relationship between forestry investment and economic growth. The forestry investment has a positive impact on economic growth. The positive impact of forestry investment on economic growth has regional heterogeneity, which is more significant in eastern and central regions, but not in western region. They have a certain "inverted U-shaped" nonlinear relationship between forestry investment and economic growth. Three policy suggestions were put forward: increasing forestry investment appropriately, improving forestry investment efficiency moderately, and adjusting the scope of forestry investment timely.更多还原
