金融资产配置与违约风险:蓄水池效应,还是逐利效应？

本文以2007—2016年中国A股上市公司为研究对象,检验了企业金融资产配置对违约风险的影响。实证研究发现:金融资产持有量越多,企业的违约风险越低,金融资产配置的“蓄水池效应”显著;在货币政策宽松时期,金融资产配置导致的代理冲突显现,宽松的货币政策会抑制金融资产投资对违约风险的降低作用。政府规制也会有一定的公司治理作用,将产业政策纳入讨论发现:对于产业政策支持的行业来说,企业金融资产配置能够降低违约风险,但是宽松的货币政策会刺激管理层的短视投资行为,抑制政府规制的公司治理作用。进一步地,本文提出会计稳健性的提升是企业金融资产配置降低违约风险的重要路径。本文的研究结论丰富了企业金融资产配置动机和违约风险影响因素的讨论,能够为政府部门防范经济运行中的内在风险提供有益借鉴。     

Parking futures: Preparing European cities for the advent of automated vehicles

The introduction of automated vehicles (AVs) is a virtual certainty. Much less certain is the timing of their introduction and how rapid the transition to full automation will be. Various governments are already working to facilitate this shift by, for example, amending and elaborating regulations to support the introduction of AVs, or supporting tests in different urban environments. Meanwhile, urban and regional planners and decision-makers are still grappling with the uncertainties and differing opinions about the possible impacts of AVs on land-use changes and location choices, particularly in relation to the space available for vehicles, both moving (i.e. roadspace) and stationary (i.e. parking space). This paper uses a backcasting approach to identify critical policy decisions and measures to be taken before the implementation of AVs, so as to achieve a more desirable, attractive and high-quality city. These policy measures primarily relate to the reuse and reallocation of parking and roadspace. Two strategic decisions are found to be essential to meet the major goals of sustainable and liveable cities: a clear commitment to a shared mobility and the delimitation of Core Attractive Mixed-use Spaces (CAMS). In order to deliver these desired urbanisation patterns, a set of three policy paths, involving eight policy packages, is proposed for the next 20–30 years. This article provides urban and regional decision-makers with examples of interventions that can be implemented beyond and during the implementation of AVs.     

经济政策不确定性与企业员工配置——来自沪深上市公司的经验证据

企业员工配置是企业内部管理的重要一环,经济政策不确定性是否会影响企业员工配置?本文以员工数量衡量企业员工配置,利用2010-2018年沪深A股上市企业数据和经济政策不确定性指数建立面板数据模型,考察经济政策不确定性对企业员工配置的影响,实证研究发现:经济政策不确定性会显著增加企业员工配置,且该影响经更换变量、调整样本容量以及内生性处理后依旧显著,该反应在还债能力较弱、盈利能力较差、股权制衡度较高、地区经济发展水平较低的企业中更为明显。文章的研究结论对于企业管理和宏观经济管控有一定的参考价值。     

非互惠的零关税待遇是否促进了受惠国的出口多样化——基于中美对非洲贸易政策的比较研究

非互惠的优惠贸易待遇是世界贸易组织和国际社会支持发展中国家尤其是最不发达国家发展的重要工具。为了评估该政策的效果,本文以中美对非洲实施的零关税待遇为例,采用2001—2017年HS8位贸易数据从整体、行业和区域层面评估了两种政策对受惠国出口多样化产生的影响。结果显示,美国零关税待遇分为AGOA-GSP和AGOA-服装两个条款,中国零关税待遇(FOCAC)在遵循WTO规则、受惠商品范围、受惠国家标准、原产地标准及政策有效期方面均优于AGOA-GSP,但在原产地标准灵活度和政策优惠力度方面低于AGOA-服装。这些特征导致三类政策对受惠国出口多样化的影响产生显著的差异。整体上,FOCAC和AGOA-服装对受惠国出口多样化均产生了显著的积极影响,而AGOA-GSP的影响不显著;行业层面,FOCAC对受惠国制造业、矿业和农业的出口多样化均产生了显著的促进作用,而AGOA的两个条款对受惠国三个细分行业出口多样化的影响均不显著;区域层面,三类政策对受惠国出口多样化的影响仅在部分区域发挥效果。     

提高出口退税能够“稳就业”和“稳外贸”吗?

近年来,全球贸易保护主义抬头加剧了各国之间的贸易摩擦。本文以中美贸易为例,探讨中国出口退税政策在稳就业、稳外贸以及应对贸易摩擦中的作用机制。首先基于1994-2020年季度数据发现:中国就业的波动较平稳;净出口则呈现高波动特征;中国就业和净出口呈现弱顺周期。这些周期特征与其他国家存在显著差异。其次构建了一个含有不完全金融市场和价格不完全传递的对称两国开放经济DSGE模型,数值模拟发现:在本国出口退税冲击和它国技术冲击下,模型能够较好地拟合中国就业和净出口的周期特征,其中财富效应和由贸易条件变化引起的支出转移效应是主要的内在传导机制。借助模型对中美贸易摩擦的反事实实验发现:中国单方面提高1%出口退税时,中国就业增长0.05%,净出口增长0.28%,呈现较强持续性,提高出口退税能够稳就业和稳外贸;当中国提高1%出口退税和美国提高1%进口关税时,中国就业增长0.03%,净出口增长0.16%,呈现较强持续性,勒纳中性不成立,此时出口退税在稳就业和稳外贸中的作用尽管有所削弱,但依然有效。     

Tax evasion by tax deferment: Sham litigation with an informal credit market

We show theoretically how tax evasion is facilitated by informal credit market through tax deferment. Our model is empirically based. Using sham litigation, tax evaders earn a higher rate of return than the stipulated penalty rate for tax evasion while the government loses tax revenue. We propose an upfront part–payment of the disputed amount of tax as a solution to the form of tax evasion we describe.     

财政政策对军民融合企业创新绩效的影响——创新投入的中介效应分析

我国军民融合战略的提出旨在促进科技创新和经济效率提升,保障国防和国家安全。基于2008—2019年我国(内地)276家上市军民融合企业面板数据，运用当期、滞后期多元回归模型和中介效应模型，实证探究财政政策对军民融合企业创新绩效的影响机制。结果表明：财政补助对企业当期创新绩效以及滞后期创新科技绩效起显著促进作用，对滞后期创新经济绩效没有显著影响；税收优惠对企业当期和滞后期创新绩效均具有显著促进作用；创新投入对当期及滞后期创新绩效均具有显著促进作用，但对滞后期的影响更加显著。创新投入的中介效应在财政补助对当期创新科技绩效和滞后期创新绩效的影响过程中显著，在税收优惠对当期和滞后期创新绩效的影响过程中显著。其中，税收优惠完全通过创新投入对当期创新科技绩效产生正向影响。     

经济政策不确定性、区域经济复杂度与企业创新行为

构建包含宏观经济政策不确定性指标、区域经济复杂度和上市公司特征变量“宏观-区域-企业”的实证面板数据，在理论分析经济政策不确定性对企业创新行为作用机理的基础上，以区域经济复杂度为视角，对经济政策不确定性与企业创新行为作用机制进行再检验。研究发现：经济政策不确定性对企业创新存在正向激励综合效应，同时，区域经济复杂度不仅能够促进企业创新行为，而且能够强化经济政策不确定性对企业创新行为的影响即抑制负向作用而强化正向作用。考虑内生性，通过替换核心变量检验稳健性以保证研究结论可靠，并且，研究企业特征发现，高科技企业和非高科技企业存在差异。     

Innovation and public procurement: Terminology,concepts, and applications

The growing awareness of public procurement as an innovation policy tool has recently sparked the interest of both policy makers and researchers. While an increasing number of studies is being published every year, an overview of the field is missing. Researchers, practitioners, and policy makers are often using ambiguous wording and have not yet reached consensus on the terminology and concepts involved. This state of affairs leads to research fragmentation and lack of knowledge convergence. For the purpose of contributing to knowledge synthesis and consolidation, this article provides a structured review of the literature on innovation in public procurement. From categorizing publications based on innovation drivers, concepts, and research approaches, the emerging structure of the field is described and synthesized into a framework of innovation in public procurement. The proposed framework differentiates between literature streams on (1) innovations in the public procurement process, (2) innovation of public services by means of procurement, and (3) the use of public procurement as a tool for demand-side innovation policy-making. For each of these streams of literature, different focus areas as well as research gaps and opportunities for future research are identified. Based on analysis of existing research, the proposed framework provides an overview of state-of-the-art knowledge, a unified terminology, and a holistic understanding of innovation in public procurement. The framework is both a point of departure for future research and a source of knowledge for practitioners.
