中介视域中的农村劳动力转移

本文将中介理论引入农村劳动力转移分析中,寻找其内在制约因素,理出了三条一级中介和两条二级中介：农村劳动力转移的合理性、农民素质提高和国外经验;培训和教育培训体系.分析了这些中介对农村劳动力转移的联系功能和阻隔功能,为整合推动转移的各种力量、勾划解决问题的方案提供了依据.     

基于中间业务的中国商业银行生产率变化

本文运用非参数Malmqusit方法实证考察了1999～2005年在银行产出定义中考虑中间业务时对中国商业银行生产率变化的影响,并把生产率分解为效率变化和技术进步.结果表明,当在银行产出中不考虑中间业务时,商业银行全要素生产率每年平均增长率为6.6%,技术进步指数年均增长率为7.1%,而考虑中间业务时生产率年增长率为8.8%,技术进步指数年均增长率为8.5%.不考虑中间业务,则会低估银行生产率水平,而考虑中间业务活动往往会导致估计的银行生产率水平的增加.考虑中间业务对银行技术进步影响比较大,而对效率似乎不显著.最后作者提出了几点政策建议.

Can Industrial Restructuring Significantly Reduce Energy Consumption? Evidence from China

This article uses China’s input–output (I-O) tables in 2002, 2007, and 2012 to estimate the real energy consumption of each sector after the I-O adjustment. The relationship between the sectors is further analyzed using the utility analysis method based on ecological network analysis. The empirical results show that although the traditional energy-intensive industries are the major energy-consuming sectors from a direct energy consumption perspective, large energy consumption by energy-intensive industries is transferred to downstream industries through intermediate products after the I-O adjustment. Specifically, the building industry and service sector are the sectors with the highest real energy consumption. With the upgrading and optimization of the industrial structure, the proportion of energy-intensive sectors in China is declining. However, the development of the service sector and infrastructure construction still requires large intermediate inputs. Thus, industrial restructuring cannot significantly reduce China’s total energy consumption.     

On the corporate use of green bonds

When do wholesalers issue green bonds to finance their socially responsible activities instead of charging a premium for the products they produce? We show that in less competitive retail markets when retailers can “skim” more of the premium that end consumers pay for socially responsible products, green bonds provide additional funds to help cover the cost of a wholesaler's socially responsible activities. Similar incentives arise if the wholesaler's input is a small component of the end consumers’ product, or if it is difficult for end consumers to identify the wholesaler's socially responsible activities.     

The nature of trade,global production fragmentation and inflationary dynamics: Cross-country evidence

This study investigates under which circumstances trade has impact on inflation dynamics by examining the independent effects of trade intensity, intra-industry trade and trade on value added. Trade in goods is decomposed into consumption (final) goods and intermediate inputs to deepen the assessment of the role of the globalisation of production activities on inflation dynamics. Open-economy new Keynesian Phillips curve (NKPC) analyses suggest that inflation is sensitive to domestic factors and that the relevance of external factors changes with respect to the nature of trade, country groups and time. Vertical intra-industry trade in intermediate inputs and value-added trade play important role, whereas final goods trade has no statistically significant effect on inflation dynamics.     

货币中介目标的国际比较*——基于DAG SVAR模型

学术界围绕最优货币中介目标的选择,在利率、简单加总货币量、迪维西亚货币量之间争论不休。本文基于DAG SVAR模型,分别对美国、欧元区、英国的银行间隔夜拆借利率R、简单加总货币量M2、迪维西亚货币量D2对物价P、产出Y影响的相对重要性进行实证比较。结果发现,在美国,M2对Y的影响最大,R对P的影响最大;在欧元区,D2对Y的影响最大,M2对P的影响最大;在英国,M2对Y和P的影响都最大。总的来说,若货币最终目标是经济增长,则美国、英国的最优中介目标是简单加总货币量,欧元区的最优中介目标是迪维西亚货币量;若货币最终目标是物价稳定,则美国的最优中介目标是利率,欧元区、英国的最优中介目标是简单加总货币量。由此可见,对于不同的经济体或者不同的货币最终目标,最优中介目标的选择可能有所不同。本文的研究结论在一定程度上是对“利率普遍优于货币量,迪维西亚货币量普遍优于简单加总货币量”学术共识的反向补充。     

我国商业银行收入结构改造

随着我国银行业对外开放的进一步扩大和金融体制改革步伐的加快,商业银行之间的竞争日益激烈。对于加快经营模式和增长方式的转变,实现经营结构的战略性调整,提高经营效益,增强核心竞争力等问题来说,我国商业银行至关重要的一个方面就是对收入结构进行改造。本文通过对中外商业银行收入来源的比较和量化分析,阐明了我国商业银行收入结构改造的必要性,并根据当前商业银行的经营情况有针对性地提出了商业银行进行收入结构改造的思路和重点发展的业务领域,促进我国商业银行全面、协调、可持续健康发展。     

中间产品市场价格歧视与纵向控制研究评述

现有经济学文献对价格歧视的研究主要集中在最终消费品市场上,关注的焦点是拥有垄断势力的厂商对消费者实施的歧视性行为。但在现实生活中,大部分商品的销售是面向中间需求的,在这样的产业链纵向关联中,生产商可能会向购买投入品的下游厂商实行价格歧视。由此,价格歧视也成为了一种重要的产业链纵向控制策略。鉴于最终消费品市场与中间产品市场的本质区别,理论研究的结果也有很大不同。本文将对有关中间产品市场价格歧视的经典论题和最新研究成果加以介绍和评述,并提出对规制政策的几点启示。
