产业转型升级示范区高质量发展的大数据分析

2017、2019年,国家发展改革委、科技部、工业和信息化部、自然资源部、国家开发银行在全国分两批遴选创设了20个产业转型升级示范区。以第一批12个示范区为对象,通过社会媒体报道和地方政府工作报告大数据分析,研究其在探索传统产业改造、新兴产业发展、绿色发展、园区建设、产业集聚、以及优化营商环境、融入国家战略、加强区域协作等方面的建设成效和典型经验,可以发现,推动国家产业转型升级示范区高质量发展,应因地制宜谋划示范区发展定位,依据功能定位实施差异化产业战略,进一步完善示范区评估考核指标体系,充分发挥中央预算内投资激励导向作用。     

Does individualistic culture impact operational risk?

Employing a sample of 2,957 operational‐risk events across 31 countries from 1990 to 2011, we find that financial institutions located in countries with higher individualism tend to have higher operational risk. This positive relation is achieved through the risk‐taking channel and the earnings‐management channel. In addition, the magnitude of operational losses is higher in more individualistic countries. The results suggest that individualism serves as an important informal institutional determinant of operational risk in an international context. Endogeneity tests and various robustness checks confirm our findings.     

Modelling with flexibility through the business cycle: using a panel smooth transition model to test for the lipstick effect

ABSTRACT

Consumer spending typically declines during periods of economic distress, but observers have noted that lipstick purchases appear to increase during recessions, which is often referred to as the lipstick effect. However, the existence of such effect has remained empirically unconfirmed. Using weekly retail scanner data on lipstick sales from 2006 to 2016 in the United States, we applied a Panel Smooth Transition Regression (PSTR) demand model to test the relationship between economic distress and lipstick sales. This flexible demand specification allows regression coefficients to vary as a function of an exogenous macroeconomic variables and fluctuate asymmetrically, non-linearly, and time-varyingly across an unlimited number of regimes. Empirical results show the income elasticity of demand for lipstick decreased rapidly from 0.31 to 0.05 during the 2007–2009 recession, then slowly rebounded to 0.31 by the second quarter of 2014, thus first empirically confirming the existence of the lipstick effect.

Does corporate governance still affect firm performance after controlling the distress factor?

We explore the impact of corporate governance on firm performance. We first identify whether corporate governance can still be an influential factor or has been largely captured by the traditional Fama-French three-factor model. More importantly, our study adds a financial distress factor to the Fama-French three-factor model to form a four-factor pricing model (labelled as the ‘financial distress four-factor model’). We find that for the US Russell 1000 firms, the financial distress four-factor model is the better model of the two models considered. We further find that the financial distress four-factor model has a higher explanatory power in capturing the return variation. We find that the differences between the return of firms with good (weak) corporate governance and the expected return are insignificantly different from zero for most portfolios in all the two models. The financial distress four-factor model, however, has the fewer portfolios with return difference being significantly different from zero, implying that corporate governance has been better priced in the financial distress factor.     

Beyond trade creation: Preferential trade agreements and trade disputes

This study investigates the effects of preferential trade agreements (PTA) on bilateral trade disputes. We construct a unique and comprehensive dataset on inter-country trade disputes from 1995 to 2007. The dataset covers 110 countries and 1,162 bilateral country-pair trade disputes. Using this dataset in a gravity-type model of trade dispute analysis, we find that countries belonging to the same PTA tend to experience fewer trade conflicts among themselves than with non-member countries. By studying various types of PTA with different dispute settlement mechanisms, we further find that the dispute-reducing effect only comes from PTA with specific provisions on dispute settlement mechanisms. Moreover, the effect is stronger if those PTA explicitly stipulate that members can also resolve their disputes via the WTO Dispute Settlement Body. However, having PTA that do not address how members should resolve their disputes may lead to more dispute initiations than in cases without PTA.

Short-term scheduling of crude oil operations in refinery with high-fusion-point oil and two transportation pipelines

In some refineries, storage tanks are located at two different sites, one for low-fusion-point crude oil and the other for high one. Two pipelines are used to transport different oil types. Due to the constraints resulting from the high-fusion-point oil transportation, it is challenging to schedule such a system. This work studies the scheduling problem from a control-theoretic perspective. It proposes to use a hybrid Petri net method to model the system. It then finds the schedulability conditions by analysing the dynamic behaviour of the net model. Next, it proposes an efficient scheduling method to minimize the cost of high-fusion-point oil transportation. Finally, it gives a complex industrial case study to show its application.
