Assessing the role of components of life satisfaction

Factors affecting subjective well-being and their gross effect measurement have been widely studied. However, how people derive utility from these factors has not been fully explored. This article provides a way to decompose the gross effect of major determinants on life satisfaction into direct and indirect effects and make inference for the latter. Because the indirect effect is nonlinear in parameters associated with different models in an equation system, it creates a problem in estimating the standard error. Besides, the categorical nature in survey data further introduces bias to the covariance estimation even asymptotically. To address these issues without knowing the form of heteroskedasticity under the null hypothesis, we propose to extend the wild bootstrap procedure in this particular context. Its robustness against various data properties is validated via several simulation experiments. Using three recent waves of World Values Survey, we find that the relative importance of life control has significantly increased recently, and endowing citizens with the right to enjoy their freedoms and liberties is a more effective policy in raising life satisfaction than promoting national income.     

粮库机电设备招投标流程

机电设备招投标一般是由甲方委托所指定的公共交易平台代为发起,在所需条件范围内设置标书内容和所需交易条件,依照法律程序所规定的程序内容,对多个参与方提交的技术方案、报价、响应条件进行评审,从中选择最接近中标单位条件的一种交易方式。本文主要针对各企业机电设备招投标事项进行归纳总结。

能源回弹效应下高碳产业低碳转型过程中的技术突变性

考虑能源回弹效应下，分析高碳产业低碳技术突变技术门槛，发现技术碳减排存在由量变到质变的门槛效应，另外还发现能源回弹对门槛效应具有显著影响。运用Hansen门限面板模型、结合CD生产函数的能源回弹模型发现：①不考虑能源回弹效应，高碳产业低碳化过程中的技术突变存在两个门槛；②考虑能源回弹作用，将减少为一个门槛，并且将延长高碳产业完成低碳技术突变所需时间。因此，为加快高碳产业低碳技术突变，有效减少碳排放，一方面应缓解能源回弹效应的影响，对能源回弹效应较大的高碳产业采取实时监控，对能源回弹较小的高碳产业采取定期检查和不定期抽检方式监控；货币政策、财政政策和产业政策相互配合，在高碳产业拉动经济增长的同时，最大限度控制能源回弹效应。另一方面，市场手段和政府职能双管齐下，协助企业低碳技术升级和设备改造，优化税收结构，弥补低碳技术升级导致的负外部性，完善高碳产业转移或市场退出机制。     

“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。     

Contracting and Reporting Conservatism around a Change in Fiduciary Duties*

We exploit an influential 1991 Delaware court ruling to examine simultaneously two types of conservatism that play important roles in resolving creditor–owner agency conflicts: contracting conservatism and reporting conservatism. The ruling expanded managerial fiduciary duties in favor of creditors for Delaware-incorporated firms in the vicinity of insolvency. In those firms, following the ruling, debt contracts are less likely to include conservative adjustments to accounting numbers used for covenant compliance (i.e., contracting conservatism decreases), while public financial reporting becomes more conservative (i.e., reporting conservatism increases). The decrease in contracting conservatism is concentrated in firms that exhibit a greater increase in reporting conservatism, suggesting that reporting conservatism is more cost-effective in resolving agency conflicts. In addition, the substitution effect is more pronounced in firms facing greater business uncertainty and firms with greater board independence.     

江西省高校研学旅行资源开发研究

近年来，高校研学旅行成为备受关注的新兴话题。文章在梳理国内外高校研学旅行研究与发展现状的基础上，通过对江西省高校特色和优质资源的把脉，明确了江西省高校研学旅行资源开发中应把握的科技类、文教类、艺术类、管理类、生态类等五大主题定位，提炼了属地化、品牌化、梯度化、融合化、联动化等五大开发原则，并基于属地精品开发、梯度重点开发、多元复合开发、分层联动开发四大视角提出了针对性开发策略。     

Who benefits from partial tax coordination?

In this paper, we investigate whether partial tax coordination is beneficial to countries within and outside a tax union, in which countries are supposed to compete in taxes and infrastructure. Our results demonstrate that a subgroup of countries agreeing on a common tax rate can harm both member and nonmember states. This is in contrast to the classical findings that partial tax harmonisation is Pareto improving. When a minimum tax rate is imposed within a tax union, we demonstrate that it does not necessarily improve the welfare of the member countries. Moreover, both the high‐tax and low‐tax countries can be worse off. This conclusion is at odds with the classical result that a high‐tax country benefits from the imposition of a lower tax bound.     

国际策略情境、国际双元学习与后发企业创新赶超

整合国际策略与双元学习理论，构建国际策略情境、国际双元学习的平衡和联合与后发企业创新赶超之间的关系模型。基于长三角地区327家外向型制造企业（高新技术企业）问卷调查数据，发现国际策略情境以及国际双元学习平衡和联合均显著正向影响企业创新赶超，国际策略情境对国际双元学习平衡和联合均具有显著正向影响，并且国际双元学习平衡和联合均在国际策略情境与创新赶超之间具有部分中介作用。研究结果揭示了国际化视域下双元学习与后发企业创新赶超的内在影响机制，延展了企业国际化、组织学习和创新赶超等相关领域理论空间，对于本土企业有效实施创新赶超具有启示意义。     

电子信息产业国内价值链省域比较优势测度及空间差异研究

为应对后疫情时代全球电子信息产业加剧的“比较优势陷阱”,中国亟需通过国内价值链省域比较优势的互补协同提升整体国际竞争力。在价值链产品内,基于垂直专业化分工框架,兼顾增值能力与劳动生产率两个维度,使用非竞争型投入占用产出模型,设计一个评测国家内部区域电子信息产业真实比较优势的新指标。结果表明,东部沿海省域比较优势强度与广度最为显著,内陆省域比较优势集中于上游能源型部门;制造业部门比较优势凸显,服务业部门比较优势相对薄弱;比较优势高省域集中度与低省域集中度的产业部门中,均存在整体比较优势强弱差异,其中,高省域集中度产业部门比较优势强度更高。
