产业集中度、企业所有制性质与企业绩效

基于我国规模以上工业企业2004年至2008年的数据,考察了产业集中度和企业所有制性质对企业绩效的影响。通过回归分析发现,以资产收益率、净资产收益率和销售利润率为内容的企业绩效与产业集中度之间具有明显的正相关关系;而不同所有制性质企业间的绩效水平也差别较大,且总体而言国有企业的绩效水平还相对较低。因此,出于提高企业绩效的目的,政府一方面应进行产业结构的优化调整,不断提高产业集中度,充分发挥企业的规模经济效应;另一方面要进一步深入推进市场化改革,在引导国有经济从竞争性行业和领域退出的同时,鼓励民间资本参与到国有企业的改革过程中来。     

中国货币当局资产负债表结构与货币政策调控方式转变

货币当局资产负债表是分析央行行为与货币政策执行情况的一个重要报表。我国货币当局资产负债表科目随着经济金融结构的演变经历了多次调整,本文梳理了我国货币当局资产负债表结构及其演变过程,重新编制1999-2018年的年度可比货币当局资产负债表,通过解析各科目余额及其结构的动态变化特征,揭示统计数据背后的经济逻辑与政策实践、以及重要资产负债科目间的勾稽关系。研究发现：外汇占款和对其他存款性公司的债权是我国货币当局投放基础货币的主要渠道。过去20年中,两种渠道此消彼长反映出我国基础货币投放方式和货币政策调控方式的两次重要转变与创新。在外汇占款大幅增长时期,货币当局曾通过频繁提高法定存款准备金率和发行央行票据回笼过剩流动性。随着国际收支顺差收窄和国内经济由高速增长向高质量发展转变,公开市场操作和创新型再贷款工具将成为货币当局主动投放基础货币的重要渠道。     

Risk and diversification of nonprofit revenue portfolios: Applying modern portfolio theory to nonprofit revenue management

This study uses modern portfolio theory (MPT) to estimate the risk of nonprofit revenue portfolios and examines to what degree the revenue concentration measure based on Herfindahl–Hirschman Index is associated with the portfolio risk measure based on MPT. The findings suggest that nonprofits with greater revenue concentration have lower revenue portfolio risk in the whole sample analysis. However, it is plausible that this result is dominated by organizations reliant on commercial income, which comprise over half of the sample. In fact, when examined separately, the relationship varies by an organization's primary funding structure. While higher revenue concentration is positively associated with portfolio risk for organizations relying on donations or those without a consistent primary funding source, it appears to associate with a lower portfolio risk for commercial organizations and those relying on government grants. This study reflects on the concept of diversification derived from portfolio theory and calls attention to a more nuanced approach to nonprofit revenue strategy.

效率结构、市场势力与我国银行绩效的动态变化

利用经资产质量和资本校正后的成本函数模型测度出我国商业银行1995年至2005年的规模经济效率和X-效率。"效率结构"假说和"市场势力"假说并不能充分解释我国商业银行市场"竞争程度提高,组织绩效恶化"的悖论,导致这一悖论的根本因素是资产价格(利率)管制、业务趋同和竞争目标的非利润化所导致的商业银行竞争中的费用偏好。     

Uneven and combined development and sub-imperialism: the internationalization of Brazilian capital

This paper examines the political-economic outgrowth of Brazilian capitalism in the global south after the outset of the global financial crisis. In analysing the public-sector finance policy of the Workers’ Party (PT) during the crisis, I argue that a structuration of investment was established. Utilizing theoretical premises of uneven and combined development and sub-imperialism, this paper traces the motions of the industrial financing processes that perpetuate Brazilian capitalism outside of the boundaries of the nation-state to shed light on the relationship between ‘emergent’ economies, their state structures, and the developing world. I argue that such structures represent a policy to accelerate capital accumulation abroad.     

Estimation and diagnostic for skew-normal partially linear models

Partially linear models (PLMs) are an important tool in modelling economic and biometric data and are considered as a flexible generalization of the linear model by including a nonparametric component of some covariate into the linear predictor. Usually, the error component is assumed to follow a normal distribution. However, the theory and application (through simulation or experimentation) often generate a great amount of data sets that are skewed. The objective of this paper is to extend the PLMs allowing the errors to follow a skew-normal distribution [A. Azzalini, A class of distributions which includes the normal ones, Scand. J. Statist. 12 (1985), pp. 171–178], increasing the flexibility of the model. In particular, we develop the expectation-maximization (EM) algorithm for linear regression models and diagnostic analysis via local influence as well as generalized leverage, following [H. Zhu and S. Lee, Local influence for incomplete-data models, J. R. Stat. Soc. Ser. B 63 (2001), pp. 111–126]. A simulation study is also conducted to evaluate the efficiency of the EM algorithm. Finally, a suitable transformation is applied in a data set on ragweed pollen concentration in order to fit PLMs under asymmetric distributions. An illustrative comparison is performed between normal and skew-normal errors.

论我国消费信贷业务存在的问题及其对策

改革开放以来,我国的消费信贷活动出现了一般消费信贷明显减少,特种消费信贷发展较快和消费心理、消费习惯发生了变化等三个新的特点。面对消费信贷活动迅速发展的新特点,银行开展的消费信贷业务却面临着业务量所占的比重小、品种少,对开展消费信贷业务的作用认识不足和缺少一套完善的消费信贷制度等问题,这些问题的存在既不能满足消费信贷活动迅速发展的需要,也束缚着我国和西方发达国家在消费信贷业务方面的竞争。为了克服这些问题,在竞争中处于有利地位,必须提高认识,突出重点,完善机制,努力提高人
