Does a Lingua Franca matter in bilateralinternational trade?
Li Su,  Hojin Jung,  MingzhuoYang     
Abstract: This article explores the impact of languageproficiency on international trade by using panel data analysis. To do so, weconstruct a time-variant test-score-based measure of common language.Controlling for the standard gravity model variables, we find strong empiricalevidence that English proficiency promotes bilateral trade flows throughfacilitating direct communication. We confirm that this finding is robust evenwhen we estimate its effects separately on goods and services trade flows at adisaggregated level. Furthermore, we show that institutional similaritiesbetween trading partners play a role that is similar to communication easinessin trade. Our study provides a policy implication for government support forattaining second language fluency.

通用语言在国际双边贸易中重要吗？

摘要：本文使用双边贸易面板数据，探讨了精通外语对国际贸易的影响。我们构建了随时间变化的、基于英语考试成绩的，对共同语言的衡量方法。在控制了相关引力模型的变量后，我们的实证结果表明，精通英语能够提升双边贸易流量。我们进一步发现，在分类产品的层面上，分别衡量其对货物和服务贸易的影响，结果依然稳健。此外，我们还证明了贸易伙伴之间的体制相似性，和交流便捷一样，也对双边贸易起到一定作用。我们的研究为政府支持提升外语水平提供了一定的政策启示。

The impact ofChina's Differential Electricity Pricing policy on fossil fuel consumption

Lin Zhao

Abstract: China, the world's largest energy consumer, has beenincreasingly relying on pricing policies to improve energy efficiency in recentyears. This paper estimates the impact of Differential Electricity Pricing(DEP) policy, which covers the most energy-intensive industries in China. Underthe DEP policy, electricity surcharges are imposed on enterprises using“eliminated” and “restricted” production technologies, of which the“eliminated” enterprises are more backward in technology level and are chargedmuch higher electricity tariffs. We exploit a differences-in-differencesapproach to assess the effect of the DEP policy on fossil fuel consumption. Theresults indicate that the DEP policy led to a reduction in coal consumptionintensity (CCI) of “eliminated” enterprises, which can be explained by theobsoleting of backward equipment in these enterprises. As for the “restricted”enterprises, it was economically optimal to continue to use “restricted”equipment; consequently, the DEP policy had no significant impact on CCI.

中国差别电价政策对企业化石能源消耗的影响

摘要：中国作为世界上最大的能源消费国，近年来越来越多使用价格政策来提高能源效率。本文估计了中国差别电价政策（Differential Electricity Pricing policy, DEP policy）对企业化石能源消耗的影响。差别电价政策涵盖了中国能源消耗强度最高的行业，该政策对高耗能行业中属于“淘汰类”和“限制类”的企业征收高于正常工业电价的差别电价。其中，“淘汰类”企业使用的生产工艺比“限制类”更为落后，加价标准也高于“限制类”企业。双重差分回归结果显示，差别电价政策促使“淘汰类”企业加快了对落后生产设备的淘汰和报废，从而有利于减少燃料煤消耗。而在限制类企业，由于加价标准较低，继续使用原有设备是企业的最优选择，因此，该政策对“限制类”企业燃料煤消耗无显著影响。

Why do weresolutely prevent minors from indulging in online games

Moye Li, Mingxiong Zhu

Abstract: The Chinese central government recently published anew regulation to strictly limit the time minors spend on online games,providing a favorable policy environment for the protection of their physicaland mental health as well as their overall development. We first provideempirical evidence that children having more frequent online entertainmentwould suffer worse school performance. We then adopt analytic hierarchy processto analyze the possible hazards of minors' addiction to online games from suchaspects as physical health, academic performance, family relationship, andteacher–student relationship. Recommendations are finally given on how toprevent minors from being addicted to online games.

为什么要严防未成年人沉迷网络游戏?

摘要：中央近期出台新规严格限制未成年人玩网络游戏的时间，为保护未成年人的身心健康与全面发展提供了有利的政策环境。本文分析了我国未成年人深度卷入高速发展的网络游戏产业的现状及危害，明确了防止未成年人沉迷网络游戏的必要性与艰巨性，并用有限标度视角下的层次分析理论从身体健康、学习成绩、家庭关系、师生关系等维度展开分析，就防止未成年人沉迷于网络游戏、保护其身心健康、实现德智体美劳的全面发展提出建议。
