环境规制、代理成本与公司绩效——来自化工行业上市公司的经验证据

本文选取2014-2018年A股化工行业上市公司为研究对象,采用中介效应模型研究环境规制、代理成本和公司绩效的关系.研究结果显示,环境规制具有降低代理成本的作用,在此基础上能够对公司绩效产生积极影响.进一步地,将总样本按照地区进行划分,发现环境规制对代理成本的降低程度在东、中、西部地区无明显差异,但对公司绩效的提升作用存在地区性差异.具体来说,命令控制型环境规制会降低公司绩效,代理成本能削弱该降低作用;市场激励型和公众参与型环境规制会提升公司绩效,代理成本能强化该提升作用,以上结论在分地区样本中仍然成立,并且市场激励型环境规制对东部地区公司绩效的提升作用明显高于中、西部地区.     

Forecasting the volatility of asset returns: The informational gains from option prices

A new class of forecasting models is proposed that extends the realized GARCH class of models through the inclusion of option prices to forecast the variance of asset returns. The VIX is used to approximate option prices, resulting in a set of cross-equation restrictions on the model’s parameters. The full model is characterized by a nonlinear system of three equations containing asset returns, the realized variance, and the VIX, with estimation of the parameters based on maximum likelihood methods. The forecasting properties of the new class of forecasting models, as well as a number of special cases, are investigated and applied to forecasting the daily S&P500 index realized variance using intra-day and daily data from September 2001 to November 2017. The forecasting results provide strong support for including the realized variance and the VIX to improve variance forecasts, with linear conditional variance models performing well for short-term one-day-ahead forecasts, whereas log-linear conditional variance models tend to perform better for intermediate five-day-ahead forecasts.     

全球系统重要性银行变化趋势研究

针对2008年金融危机中暴露出的"大而不能倒"问题,自2011年起,金融稳定委员会开始推出全球系统重要性银行(G-SIBs)名单,并对上榜银行提出了更审慎的监管要求。从已公布的9期名单看,G-SIBs成员格局发生了较大变化,欧洲G-SIBs数量不断下降,来自中国和加拿大的银行数量不断增多。为降低监管成本,多数G-SIBs采取了去同业、去复杂化的发展策略,同时加大托管、清算等金融基础设施功能的发挥,G-SIBs系统重要性得分整体呈现下降趋势。近些年来中资G-SIBs系统重要性得分持续快速上升,由此产生的监管成本值得高度关注。建议中资G-SIBs客观评估纳入G-SIBs的监管成本,实现业务发展和监管成本的平衡。

农产品供应链重构风险传导SIR建模与仿真研究

[目的]利用动力学SIR模型模拟农产品供应链重构内生风险传导过程,以期在有效把握核心重构风险传导规律基础上为整体管控重构进程风险提出前瞻性思路。[方法]基于农产品供应链重构风险整体构架和重构进程风险传导复杂网络,以湖北省243家大型连锁超市生鲜农产品供应链2007—2017年重构样本数据为研究对象,建立重构进程内生风险传导SIR模型和规划演化模式,利用Matlab软件对模型仿真得到有效管控状态下演化趋势。[结果]在以战术性重构为主导组织结构战略性重构中进程风险传导安全边际X1s超过50%,决定了其净风险阈α0(i)、β0(i),相应的业务单元和功能模块重构进程风险预警和风险恢复能力提高值是主控指标,对进程风险传导感染率x1(i)和恢复率x2(i)起主导作用。[结论]近年来土地流转驱动农产品供应链重构中组织结构重构整体具有战略性,在以战术性重构为主导风险传导管控中重点应加强业务单元和功能模块重构进程在重构易感状态(S)、感染传播状态(I)管控能力,能有效降低波动幅度。     

“高校—企业”技术转移对企业创新绩效的影响——来自经验取样法的证据

为探讨现代企业与高校之间技术转移对企业创新绩效的影响，立足我国高科技上市公司，以经验取样法为研究范式，以高管与高校之间技术转移体验及创新成效为对象，展开连续15周日记研究，结果发现：“高校—企业”技术转移会积极影响企业创新绩效，规划性博弈与功利性博弈具有中介作用，技术吸收能力具有调节作用。由此证明，在“高校—企业”技术转移合作中，企业技术吸收能力水平在历经组织间博弈后，将显著调节由技术转化而形成的创新绩效增幅。建议相关企业主动开展创新合作，并通过均衡性博弈机制完善自身技术吸收体系，实现“高校—企业”技术转移“双赢”初衷。     

工资对个人劳动供给的非线性影响：部门市场化程度差异视角

从市场经济体制的建立到经济社会高质量发展，我国不同部门市场化程度有所差异，劳动供给的部门异质性随之体现。基于中国劳动力动态调查数据，结合汉森门槛回归模型和劳动供给模型，依托部门市场化程度的差异性，文章探讨了工资对劳动力个人供给的非线性影响及其部门异质性。主要得出以下研究结论：第一，我国市场部门与公共部门劳动力的个人劳动供给有所差异。第二，工资与个人劳动供给呈现非线性关系并且存在部门异质性。实证分析结果显示，工资对个人劳动供给的影响存在三个"突变点"，工资门槛均使得工资"激励效应"加强并呈现逐步增加的趋势。第三，劳动供给的工资门槛存在性别、城乡和行业异质性。第四，随着年龄增长、人力资本积累，个人劳动时间供给趋于降低，签署书面劳工合同使得市场部门劳动力工作时间显著增加，而政治面貌显著影响公共部门劳动供给。总体来看，无论是市场部门还是公共部门，我国劳动力个人供给曲线均未"向后弯曲"，国民经济高质量发展、改善收入分配格局、提升居民幸福感等议题需持续关注。     

Chinese investment in the Brazilian soybean sector: Navigating relations of private governance

This paper examines how Chinese agribusiness firms are engaging with established systems of private governance in the Brazilian soybean sector and how that engagement is variously accommodated, contested, and configured by local realities that reflect the uneven history of transnational agribusiness development across the Brazilian agro‐export region. Using qualitative data collected at three research sites that represent different historical moments in the Brazilian agro‐export region (Mato Grosso, Goiás, and Bahia), the paper argues that the social structures underlying the particular agrarian histories of these three subregions create unique contexts Chinese firms must navigate, which in turn shapes their engagement with the private agribusiness regime across space. Although the private agribusiness regime is often portrayed as a top‐down system of governance that subjugates the polity to the demands of capital, this framing neglects to understand how that system of power is contested, negotiated, and reshaped on the ground. These three cases serve to historicize the uneven penetration of Chinese firms across the Brazilian soybean sector.     

A multi-motivational general model of entrepreneurial intention

We develop and test an overarching model of entrepreneurial intention that includes profit, social impact, and innovation as the three main drivers of entrepreneurial behavior. A holistic model is developed to identify separately the generic intention to be a self-employed entrepreneur from the associated intention to be a specific type of entrepreneur. The latter is revealed by using a conjoint experiment to reveal the individual's relative preferences for profit, social impact, and innovation outcomes. Using fuzzy-set qualitative comparative analysis we provide insights into individuals' motivations for different types of entrepreneurial careers and for their multiple pathways to the same entrepreneurial type.
