近代早期城市的能源贸易与能源消费问题——以英格兰海煤为中心

中世纪至近代早期,海煤逐渐发展成为英格兰重要的贸易商品。贸易交换的增加,带动了英格兰的海煤消费。因此有学者认为,英格兰近代早期的城市污染与海煤的贸易和使用有密切关系。通过梳理英格兰海煤的贸易轨迹,得知近代早期英格兰海煤的贸易特点:以纽卡斯尔和布里斯托尔为典型的出口港口,以伦敦为典型的进口港口。近代早期英格兰的城市污染,尽管有消费海煤带来的影响,但二者之间并不存在明显的直接相关。海煤在英格兰近代化的历程中发挥重要的积极作用。     

The coevolution of trade agreements and investment treaties: Some evidence from network analysis

Regional trade agreements (RTAs) and bilateral investment treaties (BITs) are expected to promote trade and investment relationships. One critical feature of such agreements is the network, so the multiplex coevolution of RTAs and BITs should be captured by the dynamics of their two networks. Although many studies have examined the roles of RTAs and BITs, most studies do not account for crucial network properties. This study explores how RTAs and BITs coevolve by applying a stochastic actor-oriented model of multiplex network evolution. In particular, we examine the roles of (i) cross-network dyadic interinfluences and (ii) within- and cross-network preferential attachments to discuss the dynamic relationships between RTAs and BITs. The results are as follows. First, our estimation supports cross-network dyadic interinfluences. Countries that sign a BIT are willing to establish an RTA, while those that sign an RTA are reluctant to establish a BIT. Second, concerning preferential attachments, countries prefer to sign BITs with partners that have more RTA and BIT links. However, countries tend to form RTAs with partners that have more BIT links but are reluctant to form RTAs with those that have more RTA links. We discuss possible justifications for these results, including arguments regarding the benefits and costs associated with the formation of RTAs and BITs.     

Global adjustment to US disengagement from the world trading system

US trade policy in the Trump administration is protectionist, raising tariffs outside of WTO rules, threatening trade wars, withdrawing from existing trade agreements, and negotiating new bilateral trade deals rather than free trade agreements. The reaction of the rest of the world has been to support the WTO rules-based trading system and to pursue new and expanded regional trade agreements that do not include the US. The result may be US disengagement from the world trading system, with countries diverting trade around the US. We use a global computable general equilibrium (CGE) model to analyze changes in trade and production patterns for a variety of scenarios, including US trade wars. We find that adjustment to US disengagement is feasible—the changes in trade shares as countries divert trade are modest and achievable, with very little impact on the volume of global trade. If the US engages in trade wars with major partners, the best response for other trade partners is to sit out the trade war, accept higher US tariffs, and gain markets from global trade diversion around the US. Finally, because of indirect effects, widespread tariffs fail to benefit the protected sectors—a fallacy of composition in a protectionist trade policy.     

从一则史料看清王朝与琉球王国的贸易

清乾隆时，初设于雍正七年（1729）的军机房改名军机处。军机大臣在给皇帝上奏折后，其所奏内容另行由军机处负责抄录副本存档。其中在乾隆三十一年（1766）的一本奏折中，就有关于琉球国与清王朝贸易往来的详细记录，反映了当时清政府与琉球之间的友好关系。     

Do information,price, or morals influence ethical consumption? A natural field experiment and customer survey on the purchase of Fair Trade coffee

We address ethical consumption using a natural field experiment on the actual purchase of Fair Trade (FT) coffee in three supermarkets in Germany. Based on a quasi-experimental before-and-after design the effects of three different treatments – information, 20% price reduction, and a moral appeal – are analyzed. Sales data cover actual ethical purchase behavior and avoid problems of social desirability. But they offer only limited insights into the motivations of individual consumers. We therefore complemented the field experiment with a customer survey that allows us to contrast observed (ethical) buying behavior with self-reported FT consumption. Results from the experiment suggest that only the price reduction had the expected positive and statistically significant effect on FT consumption.     

21世纪中国学界辽金经济史研究回顾与展望

辽金经济史一直是学者研究的重点,21世纪以来学界在辽金农业概况、发展原因、土地制度,畜牧业结构,货币种类、税收制度及贸易几个方面研究深入,取得了丰硕的成果。但对区域农业特点、土地买卖及粮食供给、辽金农业思想史等问题缺乏深入研究。

RCEP和中国参与全球经济治理体系改革:困境、机遇与路径

为识别中国参与全球经济治理体系改革面临的挑战,探索《区域全面经济伙伴关系协定》(RCEP)的签署为中国参与全球经济治理体系改革带来的机遇,对中国借力RCEP推动全球经济治理体系改革的路径进行研究。研究发现,既有全球经济治理体系机制建设滞后,个别国家蓄意设置治理障碍,逆全球化浪潮削弱了改革共识; RCEP能够为中国参与全球经济治理体系改革带来新的契机,有助于重构合理高效的全球经济治理机制,消弭单边和霸权主义障碍,弥合全球多边政治互信; 中国亟需紧抓RCEP签署的机遇,加快构建开放型经济新体制,凝聚区域经贸合作伙伴力量妥善处理中美竞合新关系,积极探索全球投资贸易治理机制创新,推动“一带一路”倡议与RCEP框架良好对接,守护多边主义,巩固政治互信。     

数字贸易测度的概念架构、指标体系和测度方法初探

数字贸易是构建“以国内大循环为主体、国内国际双循环相互促进”的新发展格局的新模式和新业态,也是各国参与国际竞争与合作的重要领域。然而,国际社会对数字贸易概念的认识还比较模糊,直接影响着数字贸易市场拓展和规则制定,数字贸易测度也成为国际贸易统计领域具有挑战性课题。本文在回顾和梳理国际社会关于数字贸易概念和测度方法既有论述的基础上,提出了数字贸易的“二元三环”概念架构,构建了测度数字贸易规模的指标体系,开发了以“实际数字交付比率”为关键的数字贸易测度法,并使用中国“两化融合”平台数据库的数据,对中国2018—2019 年数字贸易进出口总额进行了试测度。本文的研究成果对我国数字贸易测度研究以及有关部门建立数字贸易统计监测制度具有借鉴作用。
