跨界高端颠覆性创新模式研究：理论与案例验证

克里斯坦森的颠覆性创新理论旨在解释具有很强技术创新能力的企业顷刻间衰败的颠覆性现象。然而，现有颠覆性创新理论认为，颠覆性创新都是低端的，难以解释智能手机、固态硬盘等高端颠覆现象。通过研究固态硬盘对机械硬盘高端颠覆的案例发现：①导致行业领先企业市场地位更替的新技术，都应该被视为是颠覆性创新，而不应以技术是否具有低端属性作为判断依据；②现有理论认为，颠覆性技术首先来源于行业内部，忽略了技术创新的行业相对性，一个行业的既有技术可能对其它行业产生颠覆性效应；③外部行业企业通过外部技术对原有行业进行颠覆，这种颠覆往往表现为高端颠覆。     

Are nontariff measures and tariffs substitutes? Some panel data evidence

Using new estimates of ad valorem equivalent of nontariff measures (NTMs) over time, this paper examines NTMs and tariffs’ relationship for a sample of 70 economies for 4,949 products at the 6‐digit harmonized system level over the period 2003–2015. A panel data methodology models the lagged adjustment of NTMs to tariffs, consistent with a causal relationship. Trade policy substitution is found when the models are estimated in both levels and changes; with this holding for both OECD and non‐OECD countries, but not for the agriculture sector in OECD countries. Overall, there is a fairly complete substitution between policy instruments in absolute terms.     

Different forms of corporate philanthropy,different effects: A multilevel analysis

This study investigates how different types of corporate philanthropy impact employees' life satisfaction. Grounded in signaling theory, we explore and clarify the nuances among three types of corporate philanthropy values: the absolute value of corporate philanthropy, the value of a firm's corporate philanthropy relative to its past level, and the value of corporate philanthropy relative to the firm size. Results of multilevel analyses on a large scale sample with 218 firms and 2,261 employees at two time points reveal that: the absolute value of corporate philanthropy positively influences employees' life satisfaction; the value of a firm's corporate philanthropy relative to its past philanthropy negatively impacts employees’ life satisfaction; and the value of corporate philanthropy relative to the firm size positively affects employees' life satisfaction. The results indicate that the influences of corporate philanthropy on employees' life satisfaction vary depending on the evaluation benchmarks. Firms may benefit by taking their size and past philanthropy into consideration when making corporate philanthropy investment decisions.     

Security regulations,access to capital markets,and firm performance: Evidence from China

This study explores the cost of security regulations in China, where firms are required to meet a certain profitability benchmark before applying for permission to raise more equity via secondary equity offerings (SEOs). Using a difference-in-differences setting, we show that firms affected by the regulation (i.e., firms with high external financing demands (EFD) but profitability lower than the regulatory requirement) significantly underperform their counterparts, while unaffected firms do not. The affected firms’ performance decline increases (decreases) when the requirement of profitability is more (less) restricted. Consistently, the three-day cumulative abnormal return (CAR) of firms with high EFD is significantly negative (positive) when the regulation is tightened (loosened). Our study provides evidence on how the cost of regulation affects companies that have growth opportunities.     

高管团队异质性、团队冲突与企业绿色绩效——差异化CEO领导风格调节下的整合分析框架

基于高阶梯队等理论，从高层管理团队异质性等要素整合分析视角切入，在探讨高层管理团队驱动企业绿色绩效作用机制的基础上，尝试构建差异化CEO领导风格调节下高管团队（TMT）异质性、团队冲突与企业绿色绩效的理论模型；通过层次回归分析、Bootstrap等方法实证检验异质性高层管理团队的作用机理和边界。研究结果显示：①TMT异质性、任务冲突能显著提升企业绿色绩效，且任务冲突在TMT异质性与企业绿色绩效的关系中起部分中介效应，而关系冲突显著降低企业绿色绩效。多元化构成的高层管理团队拥有更多差异化思想，这些观点通过高层管理团队成员不断分析整合后作用于绿色绩效，而成员间“对人不对事”的关系冲突会弱化该过程，进而对绿色绩效产生负向影响；②变革型CEO领导风格负向调节任务冲突与企业绿色绩效的关系，表明CEO适度简政放权，指导、关怀和保障高管团队成员充分表达观点非常重要。交易型CEO领导风格负向调节关系冲突与企业绿色绩效的关系，说明CEO通过奖惩激励，降低高层管理团队情绪冲突，提升团队凝聚，是推动绿色转型的重要举措。     

Market Discipline and Deposit Guarantee: Evidence from Australian Banks

This study examines depositor market discipline of Australian banks and its interaction with the 2008 deposit and wholesale funding guarantee. Prior to 2008 market discipline is found for Australian‐incorporated banks. Depositors did not distinguish between major and small banks, but some differences in the degree of market discipline were found for foreign bank subsidiaries. Following the introduction of the 2008 guarantees, market discipline was reduced except for nonhousehold depositors at banks that did not access the wholesale guarantee. Market discipline is also evidenced at foreign bank branches, but weaker for those accessing the wholesale guarantee.     

基于会计结算的第三方物流企业风险防范问题的研究

第三方物流企业作为向市场交易双方提供专业化物流服务的企业,在目前物流市场交易环境、金融环境和竞争环境不够规范的情况下,其往来账款结算和信用销售存在着较大的风险.第三方物流企业会计结算中相关风险的防范和控制应从以下几个方面着手,从加强内部控制管理出发,重塑和优化会计结算的流程机制,构建有效的会计管理信息系统,外部上要对市场交易环境、竞争环境和金融环境的运行做好全面的分析、监控,强化会计结算的预测、核算和控制功能,从而对销售风险、资金结算风险和呆账坏账风险进行全面的防范和控制.     

Pricing vulnerable options with correlated jump-diffusion processes depending on various states of the economy

In this paper, we use a Markov-modulated regime switching approach to model various states of the economy, and study the pricing of vulnerable European options when the dynamics of the underlying asset value and the asset value of the counterparty follow two correlated jump-diffusion processes under regime switching. The correlation is modelled by both the diffusion parts and the pure jump parts which describe the uncertainty of the value of the risky assets. We develop a method to determine an equivalent martingale measure and a parsimonious representation of the risk-neutral density is provided. Based on this, we derive an analytical pricing formula for vulnerable options via two-dimensional Laplace transforms, and implement the formula through numerical Laplace inversion.     

Robust scheduling for multi-objective flexible job-shop problems with random machine breakdowns

This study addresses robust scheduling for a flexible job-shop scheduling problem with random machine breakdowns. Two objectives – makespan and robustness – are simultaneously considered. Robustness is indicated by the expected value of the relative difference between the deterministic and actual makespan. Utilizing the available information about machine breakdowns, two surrogate measures for robustness are developed. Specifically, the first suggested surrogate measure considers the probability of machine breakdowns, while the second surrogate measure considers the location of float times and machine breakdowns. To address this problem, a multi-objective evolutionary algorithm is presented in this paper. The experimental results indicate that, compared with several other existing surrogate measures, the first suggested surrogate measure performs better for small cases, while the second surrogate measure performs better for both small and relatively large cases.
