产业安全的内涵

不同的学者对产业安全的内涵持有不尽相同的观点.笔者认为,产业安全应当分为宏观、中观、微观三个层次,且是一个系统过程.从层次上看:中观的产业安全问题是关键与核心,是一个国家产业安全问题的集中表现;从传导路径上看:宏观产业安全问题向中、微观传递,在中、微观产业安全中得以体现;微观产业安全问题也会向中观宏观渗透.

我国粮食补贴政策体系的构建与完善

我国的粮食补贴政策,经历了由间接补贴到直接补贴发展的过程。现行的粮食补贴政策,在促进粮食增产、农民增收,确保国家粮食安全方面,发挥了积极的作用。但是在政策的实施过程中,也确实存在着一些不容置疑的问题,针对粮食补贴政策中存在的主要不足,就如何完善我国的粮食补贴政策,更好地实现政策目标,进行了思考并提出相应的建议。     

Food Aid, Food Prices, and Producer Disincentives in Ethiopia

Although the short-term aims of food aid are well conceived, strong concerns have been voiced regarding the long-term impacts of such aid on incentives for agricultural producers in recipient countries. This article examines the statistical link between food aid shipments and food prices in Ethiopia over the period 1996–2006. Monthly data from three markets and three commodities are used to estimate a system of seemingly unrelated regression models for food prices. Results indicate that previous year food aid shipments reduce prices in all producer and consumer markets. These effects, however, appear to be limited to the set of internationally traded commodities that are domestically marketed. A recursive regression procedure is used to identify the food aid threshold at which a negative aid effect emerges. Food aid shipments that constitute less than 10% of domestic production appear to be benign, but shipments above this level show signs of being disruptive to local markets. We use a simple policy simulation to argue that production-sensitive targeting, e.g., conditioning food aid on local food production, would help to circumvent disincentive effects.

钻井远程实时决策系统的开发与应用

在构造复杂地区,累计发生钻井复杂情况较高,实施安全钻井就显得非常重要。而钻井远程实时决策系统不仅可以及时对各种可能发生的钻井复杂情况进行提前决策分析,还可以在后方通过图文并茂的方式实时显示现场情况,这样后方专家就可以利用该系统进行多井远程实时决策和现场技术支持。该系统首先实现了远程数据的实时采集、统计分析已钻井资料总结出异常数据变化规律、并提出新的灰色关联理论计算方法,并对元坝272H井进行了应用测试,决策界面美观清晰,测试结果显著,得到了工程院专家的认可。

Market Incentives for Safe Foods: An Examination of Shareholder Losses from Meat and Poultry Recalls

Meat and poultry recalls, while voluntary, are carried out under governmental oversight. If firms have financial incentives to avoid being implicated in a recall situation, governmental involvement in recalls may cause firms to internalize social costs when making investment decisions concerning food safety controls. To examine these incentives, we analyze federally supervised meat and poultry recalls from 1982 to 1998 within an event study. Results show significant shareholder losses when publicly traded food companies are implicated in a recall involving serious food safety hazards. We find no evidence that the stock market reacts negatively when recalls involve less severe hazards.     

Gender,entrepreneurship and food security in Niger

In many African countries, the income generated from the informal sector and the entrepreneurship is particularly important for reducing poverty. Previous studies have not found clear evidence on the relationship between self‐employment by gender and food security. We argue that this may be a result of the gender inequality in resource accessibility. In this paper, we analyze the implication of household entrepreneurship on food security in Niger, where gender disparities in resource accessibility are reduced. We find that owning female‐managed non‐agricultural enterprises is positively related to food accessibility and food availability within female‐headed households. The results draw the attention on reducing gender differences in resource accessibility in entrepreneurship for improving food security.     

中国食品行业应诉国外反倾销的特点

近年来,中国食品行业在国际市场上屡遭反倾销投诉,企业损失惨重。因此,深刻了解国外对中国食品行业反倾销调查的特点,并采取相应措施,已成为中国企业进一步开拓国际市场的当务之急。针对上述现状,并结合国外对中国食品行业实施反倾销的四个特点,对其遭遇反倾销的原因及损害进行了深层次的分析。中国食品行业应该培养并形成自己的核心竞争力,并强化反倾销意识,这样可以从根本上改变食品行业出口频频遭遇反倾销的状况。
