Abstract ：
The convexity of meta-frontier is a debated topic in data envelopment analysis (DEA). This paper claims that meta-frontier is a non-convex hull, but the production activities between the non-convex meta-frontier and the convex traditional production frontier may be feasible. Therefore, technology compatibility is defined to explain this feasibility, and a modified DEA model is constructed to evaluate the efficiency of decision-making units with technology heterogeneity and technology compatibility. Sequentially, two new meta-frontier DEA frameworks are constructed to evaluate and decompose efficiency, thereby revealing the impact of technology heterogeneity and technology compatibility on efficiency. In addition, a series of discussions are presented to analyze these two new frameworks.

Abstract ：
长三角城市群是我国经济发展的重要引擎，探究该区域的生态福利绩效对我国的高质量发展具有重要的现实意义。为此，从资源配置视角和多维评价指标体系出发，改进了生态福利绩效的两阶段链式转化结构模型，并据此构建了考虑非期望中间产出弱可处置性的两阶段链式超效率DEA模型，测度长三角城市群2011—2021年的全局生态福利绩效及分阶段效率，并利用双固定效应下的空间杜宾模型揭示长三角城市群生态福利绩效空间溢出效应，探究长三角城市群生态福利绩效的提升路径。研究结果表明：（1）长三角城市群全局生态福利绩效的平均水平维持在0.8左右，但有68.3%的城市处于非有效状态，且城市之间存在较为显著的差距。（2）分阶段来看，生态-经济效率为0.685，经济-福利效率为0.863，差异主要来自三省一市内部，组内贡献率分别为77.39%与77.14%，发展较不均衡。（3）长三角城市群生态福利绩效具有较强的空间正相关性，而建成区绿化覆盖率、生活垃圾无害化处理率、人均GDP、城市人均每年消费额、政府干预对长三角城市群生态福利绩效提高具有正向促进效应，且建成区绿化覆盖率和生活垃圾无害化处理率有一定空间溢出效应。（4）“低经济-高福利”、“低经济-低福利”和“高经济-高福利”这三类城市最多，且分布较为均匀，而属于“高经济-低福利”类的城市最少。从提升路径来看，单边突破式是绝大多数城市弥补自身低效率阶段的最佳途径。

Abstract ：
Scientific investment forecasting can effectively avoid the blind investments of environmental management. Among existing studies in developing investment forecasting models, the extended belief rule-based system (EBRBS) showed its potential to accurately predict environment investments but also exposed two challenges to be further addressed: (1) how to select antecedent attributes from various environmental indicators for the EBRBS; (2) how to optimize basic parameters of the EBRBS based on the selected antecedent attributes. Since these two challenges are connected, a bi-level joint optimization model is proposed to improve the EBRBS for better environmental investment forecasting, in which the selection of antecedent attributes is described as an upper-level optimization model using Akaike information criterion (AIC) and the optimization of basic parameters is as a lower-level optimization model using mean absolute error (MAE). Moreover, a corresponding bilevel joint optimization algorithm is proposed to solve the bi-level joint optimization model, where ensemble feature selection and swarm intelligence optimization are regarded as the engine of upperlevel and lower-level optimizations, respectively. The real environmental data collected from 2005 to 2020 of 30 Chinese provinces are studied to verify the effectiveness of the proposed approach. Experimental results show that the EBRBS with bi-level joint optimization not only can effectively predict environmental investments, but also is able to have desired accuracy better than previous investment forecasting models.

Abstract ：
目的：从公平性和公益性双重视角出发，分析2019年我国东部地区公共卫生资源配置的效率，为优化卫生资源配置提供参考。方法：运用集聚度研究卫生资源的配置公平性，考虑医疗行业的公平性和公益性下的投入产出指标，建立改进的仁慈型交叉效率DEA评价模型。结果：我国东部地区公共卫生资源投入充足，但地区间存在差异。公共卫生资源配置效率不足，普遍受规模效率限制，资源投入冗余，规模过大的省市占82%。结论：东部地区在提高医疗资源效率的同时，应兼顾公平性和公益性，注重资源的合理配置和利用。对配置效率不高达地区给予政策和经济支持，缩小区域间差异。

Abstract ：
Logistics provider selection is a multi-criteria decision-making problem faced by e-commerce companies. Considering the complexity of the problem and the uncertainty of the decision information, an integrated approach of GTOPSIS is proposed for evaluating and selecting the most suitable logistics provider. The GTOPSIS approach integrates the three-parameter interval grey number (T-PIGN) into the technique for order preference by similarity to ideal solution (TOPSIS). It allows decision-makers to use T-PIGN to represent the performance of the alternatives which can retain and utilise the original uncertain assessment information of alternatives to the greatest extent. Besides, the PERT distribution is adopted to weight the three parameters of T-PIGN. A real-life case study is presented to demonstrate the practicality and effectiveness of the GTOPSIS approach.

Abstract ：
The allocation mechanism of carbon abatement quotas is a vital issue in the carbon emission abatement (CEA) for the environment and sustainability. The conventional CEA allocation focuses on the imposition of carbon quotas but hardly considers the techniques or mechanisms of abatement. The neglect of the abatement mechanisms may cause inapplicability and unavailability in the practical implementation of CEA allocation. To fill this gap, this paper firstly recognizes and distinguishes two kinds of non-separable relationships among energy inputs, capital investments, and carbon emission. Thereafter, three carbon abatement mechanisms are formed and defined. Then, three scenarios of carbon abatement, named managerial, technical, and hybrid scenarios, are constructed based on the carbon abatement mechanism, in which the carbon emission is, respectively, abated by reducing energy inputs and increasing capital investment and the hybrid measure of energy decrease and capital investment increase. With the developed carbon abatement mechanisms, a carbon abatement allocation application of the regional highway transportation systems in China is illustrated. It finds that the carbon abatement allocations based on the proposed carbon abatement mechanisms help to narrow the regional highway transportation system gaps in China, and the outputs perform the best under the managerial scenario. The Eastern bears more carbon abatement burdens than the Central and West under both managerial and technical scenarios. The Central and West can improve their outputs and bear more carbon abatement burden under hybrid scenarios. The central authority can choose the CEA technique and allocation scheme in line with its preference and observation.
