Covid-19-tested food labels

While the transmission of virus SARS-CoV-2 via food is rare, some Chinese food retailers are considering a Covid-19-tested food label. However, how consumers may support such a label is unknown. We quantify Chinese consumers’ willingness to pay (WTP) for food carrying a Covid-19-tested label using an online choice experiment. We find that the WTPs for such a label are always positive for all food products considered. The amount of WTP depends on the entities authenticating the labels, country of origin of the food, and consumers’ socio-demographic status. Contrary to expectation, the knowledge on Covid-19 does not affect consumer preferences for the Covid-19-tested food labels. Our benefit and cost analysis suggests a possible large benefit of creating and administering a Covid-19-tested food label. This study provides insights for policymakers, global food manufacturers, and retailers to create marketing strategies to alleviate consumer food safety concerns associated with Covid-19.     

Dialectical mind can be sweet toward crisis‐associated products/brands

Consumers’ thinking style (e.g., dialectical thinking), which is fundamental to cognition, has been paid inadequate attention in the consumer literature. This research explores the impact of dialectical thinking on Chinese consumer responses toward crisis‐associated products/brands. Findings in three experimental studies indicate that, in comparison to those primed with nondialectical thinking, consumers primed with dialectical thinking report higher levels of purchase intention and trust for a crisis‐associated product/brand. This is the case not just for products with Chinese cultural background, but also for products with western cultural background. Consumers’ perceived severity of crises moderates the impact of dialectical thinking, with a stronger impact in a highly severe crisis situation than in a less severe one. A survey study indicates a similar pattern. These findings are important in suggesting ways of encouraging Chinese consumers to be insistent on quality standard in order to better protect their consumer rights, and moreover, for multinational corporations on how best to respond and formulate strategies of handling product‐harm crises in the Chinese market.     

内外融资条件、融资约束与企业绩效——来自京津冀地区企业调查的新证据*

基于独特的京津冀地区企业调查数据和克服内生性的结构方程模型，本文对融资约束的成因及影响进行了实证分析。分析结果表明，企业自身条件和外部市场环境均对融资约束有重要影响，且企业自身条件对融资约束的影响更强。总的融资约束指标对企业绩效的影响不显著。在区分融资约束的不同维度后，本文发现，融资可得性提高显著促进了企业绩效提升，融资频率增加却降低了企业绩效，而融资获得速度（等待时间）对企业绩效没有统计上的显著影响。进一步的分析表明，无论是正规融资渠道，还是非正规融资渠道，上述结论仍然成立。利用多种政策提高企业的管理水平，改善企业的自身条件，是缓解融资约束的最有效办法。     

Institutional quality,investment efficiency,and the choice of public–private partnerships

We examine a sample of 625 public–private partnership (PPP) firms from 1980 to 2015 that straddle nine countries with varying degrees of economic development and PPP markets. We find that the motivations of the firms that undertake PPP investments vary. While private sector firms in economies with low institutional quality choose to engage in PPPs to alleviate capital constraints attributed to underinvestment, those in economies with high institutional quality participate in PPPs to solve the problem of overinvestment due to an abundant cash flow. In the long run, the benefits of lower capital constraints through PPP investments are more pronounced in economies with high institutional quality.     

多视角县级空间开发适宜性评价方法对比研究

［目的］随着市县经济社会发展总体规划的改革创新，越发强调主体功能区制度的完善、强化政府空间管控的能力。空间开发适宜性是合理划分国土空间、优化开发布局的重要基础。［方法］研究通过选取了地形地势、交通干线、人口聚集度、经济发展4项适宜性指标和自然灾害影响、可利用土地资源、可利用水资源、生态系统脆弱性4项约束性指标，建立空间开发适宜性评价指标体系，分别从格网与行政区两种视角出发，开展蒲江县级空间开发适宜性评价，采用点对点匹配度分析对两种评价结果进行综合对比分析。［结果］从总体看，蒲江县最适宜区域占比约为4%，较适宜区域占比约为14%，较不适宜区域占比约为15%，最不适宜区域占比约为67%。行政区视角下，各类开发适宜性等级区域差异明显，但街道、乡（镇）行政区内部具有均质性。具体来说，各类开发适宜性等级区有按行政区集聚的趋势，并且其集聚趋势与多指标评价结果关系密切。空间视角下，各类开发适宜性等级跨行政区，街道、乡（镇）行政区内部具有异质性。一方面，各类开发适宜性等级不受行政区影响，局部精准性更高。另一方面，形成跨行政区的开发时序判读，并且这种开发时序多呈现“中心—外围”结构，便于具体指导区域分步开发。［结论］格网尺度可以更精细地反映县级开发适宜性和开发约束性在空间上的差异化分布，提高城镇、农业、生态3类空间范围划定精准性，为合理确定资源开发强度、促进国土空间科学适度有序布局提供技术保障。     

Neither an Authentic Product nor a Counterfeit: The Growing Popularity of Shanzhai Products in Global Markets

Counterfeits have been a longstanding concern to global brand manufactures. However, recently, a new product category that partly imitates and partly innovates under the term shanzhai has entered into market. Shanzhai products mimic original leading brands through visual or functional similarities and may also provide additional features. Given this new copycat phenomenon, our study for the first time conceptually distinguishes shanzhai products from counterfeits, theoretically compares the values of consumers choosing shanzhai products versus counterfeits, and empirically tests such differences in one integrative model. Specifically, shanzhai buyers value product functional benefits more than counterfeit buyers, while counterfeit buyers value status consumption, yet experience less self‐clarity than shanzhai buyers. Our findings offer important implications for imitative innovation literature as well as for practitioners.     

Public pollution abatement and wage inequality

This paper constructs three-sector general equilibrium models to investigate how public pollution abatement affects the skilled–unskilled wage inequality. In the basic model with full employment, we find that a higher degree of public pollution abatement will decrease the wage inequality if the intensity of skilled labor in the urban skilled sector is sufficiently large and expand or narrow down the wage gap if this intensity is sufficiently small. In the extended models, we consider other four cases, and obtain the results similar or dissimilar to that of the basic model.     

智能制造有利于增加企业技术创新投入吗——基于智能制造试点的准自然实验

智能制造是我国制造业转型升级的主攻方向,而如何准确客观评价智能制造的实施效果成为亟待解决的问题.从技术创新投入视角,将智能制造试点政策实施视为一次准自然实验,采用2011-2019年制造业上市企业面板数据,通过PSM-DID方法研究智能制造对企业技术创新投入的影响.研究结果表明,智能制造显著影响企业技术创新投入,即通过提升客户集成度、供应商集成度进而提高企业技术创新投入,且促进作用仅发生在民营企业和非高新技术行业中.该发现扩展了现有研究外延,同时,为解决当前国际困局和促进智能制造的持续推广提供了重要实践价值.     

庚子赔款的债务化偿付及其影响

庚子赔款是中国近代史上最大一笔赔款,也是以长期债务形式体现的赔款。本文对庚子赔款的债务化偿付安排、利率水平、支付流程及经济影响等进行比较分析。发现:(1)庚子赔款本金4.5亿两,是清政府 1903 年财政收入的 4.33倍,但通过债务化偿付,每年支付赔款占财政收入比重逐步下降;(2)按购买力折算,庚子赔款本金约占1900年中国GDP的2.1%;(3)与当时主要国家长期债务利率相比,庚子赔款4%的利率属于中等水平;(4)将庚子赔款与德国“一战”赔款进行比较,发现赔款本金和占经济总量比重,中国低于德国,但中国每年支付赔款的财政压力高于德国;(5)庚子赔款偿付对近代中国的财税金融产生深刻影响,外籍海关税务司借机成为独立于中国政府的“第二财政”,外商银行藉此强化其“隐性中央银行” 地位,赔款还催生了货币流通的“新周期” 和“新危机”。总体上,赔款的债务化偿付安排不仅受政治外交形势主导,也与金融机构特别是银行跨国经营存在密切联系。赔款的经济影响不仅取决于偿付总量,也取决于经济治理能力和财税金融制度。国家财税金融制度落后,则受到冲击较大。     

制造业企业OFDI能否抑制其"脱实向虚"?

在分析制造业企业OFDI影响其"脱实向虚"的汇率传导机制和对外产业转移传导机制基础上,利用手工匹配的2007-2014年1229家深沪A股制造业上市公司数据进行经验研究.研究结果表明:总体上,制造业企业OFDI对其"脱实向虚"具有抑制作用;高龄的国有制造业企业OFDI对其"脱实向虚"的抑制作用更明显,低增速和低金融深化地区的制造业企业OFDI能够显著抑制其"脱实向虚";制造业企业OFDI通过汇率传导机制对其"脱实向虚"的影响尚不明显,而制造业企业研究开发型OFDI通过对外产业转移传导机制所形成"反哺效应"对"脱实向虚"的抑制作用则已经显现.
