村镇银行社会网络资本作用的实证研究

社会网络资本影响网络主体的经营绩效。本文尝试对村镇银行社会网络资本对于其经营绩效的作用进行实证,通过村镇银行经营管理人员的社会网络资本作为替代变量来测度村镇银行的社会网络资本,用信贷额增长率、利润额增长率、当地市场份额增长率三个问题来衡量村镇银行经营绩效。结果表明村镇银行经营管理人员的社会网络资本对其经营绩效正面影响不显著,但可以通过提高村镇银行市场和非市场发展能力来提高其经营绩效。     

The effects of customer and supplier involvement on competitive advantage: An empirical study in China

The focus of this paper is on the effects of customer and supplier involvement on competitive advantage in the firm. Using the resource-based view and knowledge-based view of the firm, hypotheses are developed concerning customer involvement, supplier involvement, and competitive advantage. Hierarchical multiple regressions are employed to test the hypothesized relationships. The data used was collected from 139 Chinese manufacturing firms across different industries. Each variable except control variables in the model is measured by a number of scale items. Both reliability and validity (content validity, convergent validity, and discriminate validity) are demonstrated. The results of the regression analysis show that (1) customer involvement has positive impact on product quality, delivery reliability, process flexibility, and customer service; and (2) supplier involvement leads to decreased cost. These findings are interpreted in the context of Chinese manufacturing setting and enhance the understanding of the roles of customer and supplier involvement in China's business environment.

Research on the time-varying effects among green finance markets in China: A fresh evidence from multi-frequency scale perspective

Green finance is an essential instrument for achieving sustainable development. Objectively addressing correlations among different green finance markets is conducive to the risk management of investors and regulators. This paper presents evidence on the time-varying correlation effects and causality among the green bond market, green stock market, carbon market, and clean energy market in China at multi-frequency scales by combining the methods of Ensemble Empirical Mode Decomposition Method (EEMD), Dynamic Conditional Correlation (DCC) GARCH model, Time-Varying Parameter Vector Autoregression with Stochastic Volatility Model (TVP-VAR-SV), and Time-varying Causality Test. In general, the significant negative time-varying correlations among most green finance markets indicate a prominent benefit of risk hedging and portfolio diversification among green financial assets. In specific, for different time points and lag periods, the green finance market shock has obvious time-varying, positive and negative alternating effects in the short-term scales, while its time delay and persistence are more pronounced in the medium-term and long-term scales. Interestingly, a positive event shock will generate positive connectivity among most green finance markets, whereas a negative event including the China/U.S. trade friction and the COVID-19 pandemic may exacerbate the reverse linkage among green finance markets. Furthermore, the unidirectional causality of “green bond market - carbon market - green stock and clean energy markets” was established during 2018–2019.     

商业银行不良贷款的宏观经济影响因素分析

商业银行不良贷款总额一直在高位徘徊,成为制约中国商业银行发展的重要因素之一.通过收集2004年1季度～2009年1季度的最新数据,运用相关分析、共线性诊断、主成分回归分析等方法建立模型,探讨宏观经济因素对商业银行不良贷款的影响和贡献率.由实证结论发现:宏观经济因素与不良贷款余额负相关;社会消费品零售总额、进出口总额对降低商业银行不良贷款的贡献度最大,每增加1%会导致不良贷款平均降低0.0249%和0.0248%;宏观经济因素对降低不良贷款有正向促进作用,因此,在操作层面上可通过扩大内需、改善商业银行的外部信用环境等措施间接降低商业银行的不良贷款.     

The impacts of share pledging on firm investment timing and valuation

This paper applies a model in the real options framework to analyze the impacts of controlling shareholder’s share pledging on corporate investment timing and valuation. We find that the optimal investment timing shows an inverted U-shape with the pledge ratio, indicating that share pledging exacerbates firms’ over-investment and worsens firms’ under-investment. Furthermore, share pledging hurts firms’ option value unless active measures are taken to control the pledging risks. The maintenance requirement can keep controlling shareholder from irrational early investments and protect investors from severe wealth losses. In addition, our work can provide testable empirical implications.     

收入分配公平的衡量——基于等基尼系数线的平均增长点方法研究

文章在基尼系数的基础上,提出了等基尼系数线、平均增长点等相关概念,构建了用于判断收入分配公平性的平均增长点方法,认为在等基尼系数线的条件下,平均增长点横坐标数值越大(不超过0.8时)其代表的收入分配越为理想.通过对湖南省1998、2005以及全国2005、2007年的城镇居民收入分配公平状况的实证分析,论证了基于等基尼系数线的平均增长点方法在判断居民收入分配公平状况的有效性.     

COVID-19 as a stress test: Assessing the bank regulatory framework

The broad economic damage of the COVID-19 pandemic poses the first major test of the bank regulatory reforms put in place after the Global Financial Crisis. Our study assesses the U.S. regulatory framework, with an emphasis on capital and liquidity requirements. Prior to the COVID-19 crisis, banks were well capitalized and held ample liquid assets, which partly reflects enhanced requirements. The overall robust capital and liquidity levels resulted in a resilient banking system, which maintained lending and market making through the early stages of the pandemic. Trading activity was a source of strength for banks, reflecting in part a prudent regulatory approach. That said, leverage requirements are associated with more repo position netting by banks, with potential implications for market making.
