Dilemmas and Optimization of Third-Party Assessment System in Chinese Fair Competition Review

The current predominant self-review mechanism by policy-making bodies suffers from deficiencies such as insufficient motivations, limited review capabilities, and weak external supervision. Third-party assessment, characterized by independence and specialization, is designed to mitigate these shortcomings. However, the implementation of third-party assessment faces challenges too. This paper intends to improve the third-party assessment system and to realize the legislative purpose of the system. Based on social research, discussions and exchanges with relevant parties, and the existing research results, this paper analyzes the challenges and possible optimization measures for the third-party assessment. The challenges include repulsion from policy-making bodies, insufficient independence of assessment bodies, disparity of assessment quality, and limited application of assessment outcomes. Possible optimization measures include promoting fair competition culture, increasing the acceptance of third-party assessment from policy-making bodies, enhancing the quality of third-party assessment, clarifying the relationship between policy-making bodies and assessment bodies, ensuring the independence of third-party assessments, and promoting the application of assessment results.

加入水汽—温室效应后的Sellers模式

本文以Sellers(1969)模式为基础,加入水汽——温室效应的正反馈机制,计算地球上纬向年平均温度的稳定分布和进行一系列的敏感性试验。与Sellers的计算结果相比较后发现,加入水汽温室效应以后,全球平均温度提高了2.1℃。此外还分别考虑了太阳常数,反照率、大气减弱系数以及人类活动对气候的影响。结果指出:如果太阳辐射减少了1％,则相应的各纬圈年平均温度会减少1～2℃。当太阳常数减少到3％时才会触发极冰——反射率——温度的正反馈机制,而导致新的冰川期的形成,同时还发现加入水汽——温室效应正反馈机制以后,会使极冰——反射率——温室的正反馈机制有所收敛,并且可预测人类活动的影响能导致全球气候变暖。

市场是否挤出了信任:一个来自实验经济学的考察

市场是否挤出了信任是社会科学共同关注的一个基础性问题。本文运用信息不对称的经验品模型模拟了“有市场”环境,同时运用组内设计和数据平移创造性地设计了一个博弈结构完全相同的模型来刻画“无市场”环境,并设置了七个实验局分别剥离了市场中的语言描述、消费者选择权、商家定价权三个要素,从而全面对比了“有市场”与“无市场”时信任水平的差异。实验结果表明:首先,市场能够有效提升信任水平,市场与信任可形成正反馈,这进一步凸显了市场在资源配置中的决定性作用;其次,消费者选择权与商家定价权所发挥的作用并不对称,其中消费者选择权是关键因素,保护消费者权益对于构建一个良性有效率的市场尤为重要;再次,声誉是消费者选择权促进信任水平提升的重要渠道。本文加深了我们对市场自由竞争本质以及市场机制运行的理解,并为我国的市场化改革提供了重要启示:要尊重市场运行规律、强化竞争政策基础地位、保障消费者权益。

感知平台卖家亲组织非伦理行为对消费者参与价值共创的影响——互动地位感知视角

基于社会相互依赖理论与应对理论,探索互动地位感知与感知平台卖家亲组织非伦理行为(Unethical Pro-organizational Behavior,UPB)对消费者参与价值共创的交互作用机制。研究结果为:互动地位感知与感知平台卖家UPB对消费者参与价值共创存在交互效应;当明确消费者互动类型时,感知平台卖家UPB与互动地位感知的交互作用消失;关系型互动→共情在平等地位感知与感知平台卖家UPB正面性交互影响消费者参与价值共创之间发挥的顺序中介效应更为显著,而交易型互动→厌恶在支配地位感知与感知平台卖家UPB负面性交互影响消费者参与价值共创之间发挥的顺序中介效应更为显著。研究结果可以帮助平台型电商组织的管理者明确互动过程中消费者对平台卖家UPB的认知、态度与行为反应,进而为平台型电商组织的治理提供一定的经验借鉴与理论指导。

在线服务失败类型对消费者重购意愿的影响研究

为研究电商卖家在线服务失败类型对消费者重购意愿的影响,文章从消费者感知信任入手,针对两种情形下(电商卖家未达到平台规则vs未达到卖家承诺)开展了实证研究。结果表明,电商卖家相比较未达到卖家承诺,未达到平台规则,消费者对该卖家的感知信任更高,并且有更高的重购意愿。并且卖家声誉在上述关系中起调节作用。相比较高卖家声誉,电商卖家达到卖家承诺而未达到平台规则对消费者重购的负向影响程度在低卖家声誉的卖家中更加得以体现。

存在停售第三方卖家的复合型电商平台定价模型

数量众多的第三方卖家是一种战略资源,对复合型电商平台发展有重要意义。然而,观察发现:很多销量为零的第三方卖家(称之为停售第三方卖家)长期停留在复合型电商平台上。这些停售第三方卖家除了缴纳技术服务费外,无法给电商平台带来扣点收入,却会增加消费者筛选产品的成本,进而降低交易效率。基于这一现象,本文构建了一个包含停售第三方卖家的复合型电商平台模型,分析停售第三方卖家数量对均衡结果的影响,探讨他们对复合型电商平台的策略价值。研究发现:由于均衡解所处区域不同,停售第三方卖家的存在可能加剧也可能缓解平台自营和在售第三方卖家之间的竞争;与不存在停售第三方卖家情形相比,适当数量的停售第三方卖家可以同时提高复合型电商平台和在售第三方卖家的利润;控制第三方卖家总数量总是对在售第三方卖家有利,是否有利于复合型电商平台取决于单位交易成本获得的基本效用和技术服务费;当消费者更偏好平台自营时,在售第三方卖家利润会减少,复合型电商平台利润可能增加也可能减少。

复合型电商平台的演化路径分析

针对电商平台平台演化路径问题,构建了一个代表性复合型电商平台模型,比较“先平台后自营”与“先自营后平台”两条演化路径的差异,研究平台自营和第三方卖家的最优进入策略.研究发现:第三方卖家在“先自营后平台”模式始终获得较大的利润,而复合型电商平台在哪种模式获得较大利润取决于第三方卖家数量的多少;“先平台后自营”模式和“先自营后平台”模式均为纳什均衡解,且不受第三方卖家边际成本的影响.之后,将平台自营的不进入策略、保守型第三方卖家两个因素依次引入基本模型.进一步发现,当扣点率较小(大)时,复合型电商平台(纯平台)模式是纳什均衡解;若冒险型和保守型第三方卖家数量恒定不变,无论是哪种卖家,其均衡利润都与保守型第三方卖家数量呈倒U型关系.复合型电商平台运营者应采取适当限制第三方卖家数量,并控制平台开放速度.

Impact Damage Testing Study of Shanxi-Beijing Natural Gas Pipeline Based on Decision Tree Rotary Tiller Operation

The North China Plain and the agricultural region are crossed by the Shanxi-Beijing natural gas pipeline.Resi-dents in the area use rototillers for planting and harvesting;however,the depth of the rototillers into the ground is greater than the depth of the pipeline,posing a significant threat to the safe operation of the pipeline.Therefore,it is of great significance to study the dynamic response of rotary tillers impacting pipelines to ensure the safe opera-tion of pipelines.This article focuses on the Shanxi-Beijing natural gas pipeline,utilizingfinite element simulation software to establish afinite element model for the interaction among the machinery,pipeline,and soil,and ana-lyzing the dynamic response of the pipeline.At the same time,a decision tree model is introduced to classify the damage of pipelines under different working conditions,and the boundary value and importance of each influen-cing factor on pipeline damage are derived.Considering the actual conditions in the hemp yam planting area,targeted management measures have been proposed to ensure the operational safety of the Shanxi-Beijing natural gas pipeline in this region.

可再生能源发电与售电企业绿证配额交易的激励机制研究

鼓励售电商积极履行可再生能源配额义务是平衡配额制度与售电市场改革关系的契合点。本文构建了可再生能源发电商与售电商上下游企业展开配额交易合作的决策模型,解构了单次合作路径下的外部激励、连续合作路径下的双重激励模型。主要结论表明:外部补贴促进了单次合作收益的增加,电证捆绑是售电商完成配额目标的重要途径,且对应一个最佳补贴额度。若政府提高补贴额度,电证分离的交易模式能够产生显著的激励效果。在连续合作路径下,发电商获得最大收益的条件是利益共享比例较高,平均分担配额成本;但降低成本分担比例仍会导致绿证价格增加。不论采用何种配额交易模式,内部合作利益协调机制都能够抑制市场电价和绿证价格的上涨。研究为政府设计可再生能源配额制度与售电侧改革方向相适应的激励方案提供理论依据。

激进卖空者的业绩持续性

本文研究了激进卖空者在识别做空目标时是否表现出持续的横截面业绩差异,以及他们的业绩持续性是否随着从业时间的变化而变化。利用数据提供商跟踪的激进卖空者样本,本文发现,当使用目标公司股票收益率作为业绩衡量指标时,未能发现激进卖空者业绩具有持续性的证据,但如果激进卖空者过往选择的做空目标中有较高比例的公司退市,则当前做空目标在未来经历退市的可能性更大。投资者意识到了这一业绩的持续性,并且对历史做空目标中有更多退市记录的激进卖空者发起的做空行动反应更为强烈。此外,本文发现,识别做空目标的业绩持续性在激进卖空者从业生涯早期更高,但随着他们发起的做空行动增多,这种业绩的持续性会下降。这些证据与激进卖空者在职业生涯初期面临更大的声誉激励一致,并支持了Benabou and Laroque(1992)的动态声誉模型。
