摘要:研究林业产业生态效率能够准确了解到目前南方林区林业产业可持续发展水平，对于林业产业发展和生态文明建设有着重要意义。运用非径向方向距离函数测算2005年到2016年间南方林区（13个省域）的林业产业生态效率，分析其时空演变规律，对比分析各省域的资源效率和环境效率，运用变系数模型对不同省域的影响因素进行实证分析。结果表明：（1）2005-2016年间南方林区产业生态效率总体是呈缓慢上升趋势，生态效率均值最高的是广东，其次为江苏和浙江，排在最后三位的是广西、贵州、云南；除了广东、江苏、浙江、福建，其他9个省的林业产业生态效率值均值低于0.5，说明林业产业生态效率整体水平较低且呈现显著的较大差异；根据时空演变可看出，中部地区与东部地区的差距在逐渐缩小，但西部地区整体水平较低，仍有较大的提升空间，与各省份经济实力的梯次分布基本趋同。（2）林业产业生态效率提升重点在环境效率，特别是中西部地区环境效率相较东部地区还有较大的提升空间，其中环境效率中废气、废弃物排放效率是减排重点。（3）环境规制对于林业产业生态效率影响最大，其次市场化对林业产业生态效率影响较大，森林覆盖度对林业产业生态效率影响跟自身经济发展水平有关，固定资产投资对于林业产业生态效率影响是最为不显著的。文章从研究数据的局限性以及未来研究的重点方向等方面也进行了详细的探讨。



Abstract:The study on the ecological efficiency of forestry industry can accurately show the current sustainable development level of forestry industry in South China, which has a great significant meaning for the development of forestry industry and the construction of ecological civilization. In this paper, Non-radial Directional Distance Function(NDDF) is used to measure the ecological efficiency of forestry industry in southern forest regions (13 provinces) from 2005 to 2016, by analyzing Spatio-temporal characteristics. Then, resource efficiency and environmental efficiency of each province are compared and analyzed. Finally, Variable Coefficient Model is used to make empirical analysis on the influencing factors of different provinces. The results showed that:(1)from 2005 to 2016, the overall ecological efficiency of the forest industry in southern China showed a slow increasing trend, with the highest average of ecological efficiency in Guangdong, followed by Jiangsu and Zhejiang, and the last three in Guangxi, Guizhou and Yunnan; the average value of ecological efficiency of forestry industry in nine provinces such as Anhui, Guangxi and Guizhou is lower than 0.5,which indicates that the overall level of ecological efficiency of forestry industry is relatively low with significant differences; according to the temporal and spatial evolution, the gap between the central region and the eastern region is gradually narrowing, but the overall level of the western region is relatively low and still can make a great improvement, which is basically similar to the echelon distribution of economic strength of each province.(2)The key to improve the ecological efficiency of the forestry industry is environmental efficiency, especially in the central and western regions, where there is still more room for improvement,compared with the eastern regions. Among them, emission reduction priorities are the emission efficiency of waste gas and solid waste.(3)Environmental regulation has the greatest impact on the ecological efficiency of forestry industry, followed by marketization, which is the second largest impact. The impact of forest coverage on the ecological efficiency of forestry industry is related to its own economic development level, and the impact of fixed asset investment on the ecological efficiency of forestry industry is the least significant. At the end of the paper, the limitations of the selection of research data and indicators and the key directions of future research are discussed in detail.
