改造我们的教学

进入"双高时代",我们距离新时代高等职业教育"舞龙头"的教学还有问题和"短板",应该改造教学方法和学习与研究制度。在剖析改造教学原因的基础上,厘清看待教学中存在问题的两种互相对立的态度,提出改造教学的革故鼎新路径,如强化"课堂教学为王"的意识,强化学习与专业研究,强化教学的职业素养,强化教师的课堂教学治理。     

中国自由贸易试验区的改革深化与自由贸易港的建立

中共十九大为中国自由贸易试验区下一步的发展指明了方向。中国自由贸易试验区在经济市场化方面取得重大进展,颁布了一系列法律规范,旨在营造国际化、法制化和市场化的营商环境,但在开放方面还不够深入和系统化,因此十九大为自由贸易试验区的进一步发展提出了更高目标,指明了新的方向。我们建议把每个自由贸易区分为海关监管的自由贸易区和非海关监管的改革试验区。自由贸易区把成熟的经验推广到改革试验区,改革试验区再把经验推向全国。所有的自由贸易试验区采用不同模式,包括货物贸易和服务贸易自由贸易区、直接投资与金融自由贸易区和金融中心自由贸易区等。

Tick Size and Financial Reporting Quality in Small-Cap Firms: Evidence from a Natural Experiment

Using a natural experiment (the SEC's 2016 Tick Size Pilot Program), we investigate the effects of an increase in tick size on financial reporting quality. The tick size pilot program reduces algorithmic trading (AT) and increases fundamental investors’ information acquisition and trading activities. This in turn increases the scrutiny of managers’ financial reporting choices and reduces their incentives to engage in misreporting. Using a difference-in-differences research design, we find a significant decrease in the magnitude of discretionary accruals, a significant reduction in the likelihood of just meeting or beating analysts’ forecasts, and a marginally significant decrease in restatements for the treated firms in the pilot program. Furthermore, we find that the change in financial reporting quality is concentrated in treated firms experiencing decreases in AT and increases in information acquisition activities. We also find that the mispricing of accruals is significantly lower for treated firms. Taken together, our results suggest that an increase in tick size has a causal effect on firms’ financial reporting quality.     

Assessing effects of federal crop insurance supply on acreage and yield of specialty crops

Crop insurance may affect harvested acreage and yield by influencing producers’ behavior such as land allocation and input use. Although specialty crops are a major source of farm income, especially on the U.S. west coast, they have not received as much attention as field crops in previous empirical studies. This paper assesses the effect of moral hazard and adverse selection associated with the federal crop insurance program (FCIP) on the acreage and yield of major specialty crops in California. An econometric method that expands the switching regression model is developed to assess the effect. Results suggest that federal crop insurance can change specialty crop growers’ production responses to climate and soil conditions. The moral hazard effect tends to increase the acreage and yield of the specialty crops, whereas the adverse selection effect tends to have the opposite effect. The overall effect of the FCIP on acreage and yield of specialty crops is found to be moderate.     

珠海市跨境电商产业培育政策评价研究

为了研究珠海的跨境电商产业政策的效果,本文利用文本挖掘与PMC分析方法,选取珠海市跨境电商7项典型支持政策,建立13项一级指标和60项二级指标,对政策进行评价,结果显示:1项跨境电商政策评价为完美,2项评价为优秀,其余4项为可接受。就一级指标分项来看,加大资金投入、推进对外贸易发展、提高海关便利、作用对象和促进产业集聚方面表现较好,其他方面有待改进。结合珠海跨境电商政策与珠海实际情况,发现珠海在发展跨境电商方面存在四个主要问题,分别是过分注重资金投入、对跨境电商产业链认识不足、对跨境电商产业支持对象认识不清、跨境电商法律治理能力重视不够等问题,并针对上述四个问题,提出解决对策,期望为珠海跨境电商产业的进一步发展提供政策的改进与完善对策。

企业核心能力生命周期的特性

核心能力在企业发展的过程中是动态发展的,并且存在一个从培育、形成、提高到再生或者衰退的生命周期过程。核心能力是企业取得长期竞争优势的源泉。因此,企业决策者在企业发展过程中必须对核心能力生命周期的各个阶段的特性予以清楚地了解,以便企业根据特性通过具体的运作来实现核心能力的维护和提升,从而达到核心能力持续成长的目的。     

浅议国际贸易学科研究领域与方向的拓展

我国对外经济与贸易涉入的领域日益扩大,但国务院学位办和教育部研究生办及很多学校界定的国际贸易学科的研究和学习范围比较狭窄,主要局限于外贸及其与之有关的理论与政策,而对与外贸有直接关系且地位日渐重要的生产要素跨国流动等领域重视不够或不认为是其研究范围,学科名与专业名容易混淆,社会、学生、同行都有误解,影响对人才的培养与就业领域的拓宽,故有必要拓展它的研究领域和方向,将学科名与专业名互换或都定为国际经济与贸易.
