摘要: 生态产品是事关人类生命健康、经济社会建设的世界性稀缺产品.为了更好地分析生态产品有效供给问题,找出生态产品有效供给的规模效率的变化规律,本研究利用2004—2015年的面板数据,以劳动力、资本、能源和技术为投入变量,以GDP、生态产品和非期望产出为产出变量,运用SBM-Undesirable模型和泰尔指数对我国生态产品有效供给的规模效率及其差异性进行测算,并运用Tobit模型进一步对其影响因素进行实证分析.结果表明: 我国生态产品供给规模效率在2011年以前呈下降趋势,以2012年为转折点呈现上升态势,但地区间仍有较大差距.全国及各地区生态产品有效供给效率的影响因素不尽相同,从全国总体情况看,经济发展水平、产业结构(第二产业增加值占GDP比重)、科技投入、金融资本投入(环境污染治理占GDP比重)、能源消费结构(煤炭消费量占能源消费总量比重)和农业面源污染的影响为负,而生态空间及外贸结构的影响为正;在东部地区,产业结构、科技投入、金融资本、能源消费结构和农业面源污染的影响为负,经济发展水平、生态空间及外贸结构的影响为正;在东北地区,经济发展水平、农业面源污染和外贸结构的影响为负,产业结构、科技投入、能源消费结构和生态空间的影响为正;在中部地区,经济发展水平、科技投入、金融资本、能源消费结构、农业面源污染和生态空间的影响为负,产业结构和外贸结构的影响为正;在西部地区,产业结构、能源消费结构和农业面源污染的影响为负,经济发展水平、科技投入、金融资本、生态空间及外贸结构的影响为正.在进一步对以上实证测算进行理论分析的基础上,从供给侧改革的角度提出有效提高生态产品供给规模效率的政策启示,包括注重转变经济发展方式、优化生态系统结构和遵循生态法则进行整体治理等.

Abstract: Eco-product is scarce product with consequences on human health, economy and society all over the world. In order to understand the effective supply of eco-product and figure out its law of scale efficiency, panel data from 2004 to 2015 with labor force, capital, resource, and energy source was carefully selected as the input variables and GDP, sustainable product, and undesirable output as the output variables, the scale efficiency and its differences of effective supply of eco-product in China were measured in this study. SBM-Undesirable model, Theil index, and the model of Tobit were used to analyze the driving factors. The results showed that there was a downward trend in scale efficiency of China’s eco-products before 2011, and an upward trend with obvious inter-regional differences since 2012. The influence factors of supply efficiency of eco-product greatly varied among different regions. Overall, some factors had negative influences, including the values of economic development level, industrial structure (the proportion of secondary industry’s increase in GDP), science and technology input, financial capital input (the proportion of environment pollution control investment in GDP), energy consumption structure (the proportion of coal consumption in overall energy consumption), and agricultural non-point source pollution. Some factors had positive influences, such as eco-space and foreign trade structure. In Eastern China, factors such as industrial structure, science and technology input, financial capital, energy consumption structure and agricultural non-point source pollution had negative impacts, while the factors of economic development level, eco-space and foreign trade structure had positive impacts. In Northeast China, the factors of economic development level, financial capital, agricultural non-point source pollution and foreign trade structure had negative impacts, while the factors of industrial structure, science and technology input, energy consumption structure and eco-space had positive impacts. In Central China, the factors of economic development level, science and technology input, financial capital, energy consumption structure, agricultural non-point source pollution and eco-space had negative impacts, while the factors of industrial structure and foreign trade structure had positive impacts. In Western China, the factors of industrial structure, energy consumption structure, and agricultural non-point source pollution had negative impacts, while the factors of economic development level, science and technology input, financial capital, eco-space, and foreign trade structure had positive impacts. Based on further theoretical analysis of above-mentioned empirical measurement, some poli-cy implications were put forward for effectively improving the efficiency of eco-product supply from the angle of supply-side reforming, which included emphasizing the transitions mode of sustainable economy, optimizing ecosystem structure, and managing ecosystem as a whole according to natural laws.
