替代产品投放策略与竞争性反应研究

本文首先介绍了产品替代理论，然后回顾了新产品投放及竞争者的反应方面的相关理论研究，在投放策略与反应之间引入信号的概念：根据已有文献研究总结得出企业感知信号的不同类型与其做出竞争性反应的关系。     

建设具有福建特色的生态农业──兼谈发展福建绿色产品的问题

福建省人多地少，常规的传统农业已不能使农业持续地发展，发展生态农业可以利用广阔的山地、海洋、滩涂、草地资源，生产各种品质优良、无污染的绿色产品。这是具有福建特色的生态农业，前景广阔。

Environmental regulatory enforcement with “green” consumers

We consider a standard probabilistic model of random monitoring to analyze the interactions between a firm and a monitoring agency in the presence of “green” consumers when compliance payoffs are contingent on monitoring and monitoring costs are shared by the monitoring agency and the firm. When the amount paid by the firms if monitored is exogenously fixed, we find that full compliance is implemented with a finite fine. If there is an upper bound for the fine and the regulator determines endogenously the fine and the amount paid by the firms if monitored, we find that full compliance is also achieved, although the optimal fine is now set at its maximum level. The optimal amount paid by the firms if monitored is lower than the environmental premium the compliant firm gets.The author thanks two anonymous referees for their useful comments and suggestions     

对企业技术创新自我实现的经济学分析

本文从经济学的理论角度分析了企业技术创新自我实现的可能性。分析发现：产品被成熟生产后的产量与资本报酬和资本边际生产率的大小有直接关系。因此，企业发展内部本身就可以通过市场供需调节来实现创新的循环和延续。从这一点上说，国家对于企业技术创新的鼓励政策应该更加依靠市场机制的作用。     

A model of multiple-unit ownership as a diffusion process

This paper develops and tests a new model for multiple-unit adoptions of durable goods based on the diffusion modeling tradition. Multiple-unit adoptions are a major component of sales for many consumer durable product categories. For instance, sales of multiple-unit adoptions for televisions have been higher than both first adoptions and replacement purchases since 1977, while for automobiles, they have represented more than 20% of sales since 1966 in Australia. The structural drivers of multiple-unit adoptions are quite different from either first purchase or replacement purchase. Hence, identifying and modeling the multiple-unit component of sales is important for aggregate sales forecasts. Moreover, consumer requirements for additional units of a product are likely to be considerably different than for the other components of sales (first purchases and replacement purchases). As such, the ratio of the first, multiple, and replacement sales components will strongly influence the product mix requirements of the market.

While forecasting and influencing multiple-unit sales are an important managerial issue, very little attention has been given to multiple-unit ownership in the diffusion modeling literature. The only model available was developed for the purpose of modeling relatively short-term behavior of multiple-unit adoptions, rather than the longer-term pattern of sales. We propose a model of multiple-unit adoptions as a diffusion process.

We apply the model to both color television and automobiles. Analysis of the model's long-term fit and forecasts in these applications provide support for the structure of the new model.     

辽宁沿海经济带地脉文化旅游开发利用的经验、问题与对策

地脉文化也被称为地脉和文脉，是一个地方旅游发展的基石。根据地脉文化与旅游产品关系对比可以将旅游开发分为两类四型：（1）旅游产品扎根于地脉文化发展模式 （根基稳固、主次分明）；（2）旅游产品脱离地脉文化发展模式 （左顾右盼、横生枝节）。本文根据这一基本原理对辽宁沿海经济带旅游发展及旅游产品进行了系统分析，总结了辽宁沿海经济带地脉文化旅游开发利用的经验、问题与对策建议。结果显示：辽宁沿海经济带的地脉文化基础有 “海” “滩” “宜” “河” “港” “城” “工” “农” “山” “史”十大方面。 “海” “城” “山”的旅游产品是辽宁沿海经济带各地当前旅游发展主要方向； “滩” “农” “史”旅游产品是辽宁沿海经济带各地当前旅游发展主要方向； “滩”“农”“史”正在发展； “宜”（宜人气候、度假资源）表面发展丰富，实际潜力巨大； “河”（河流、湖泊、水库） “港” （港口） “工”（工业旅游）是被忽视或者发展滞后的地脉文化资源。     

垂直专业化贸易:理论模型与基于中国数据的实证

国际贸易理论研究的最新论题之一是对国际垂直分工以及基于垂直分工贸易的关注,本文在较为系统梳理这方面最新研究成果的基础上,从产品内国际垂直分工的角度切入,测算了中国典型年份的垂直专业化贸易程度,并对一些影响因素进行了回归分析。结果显示机械设备制造业占我国垂直专业化贸易份额的30%以上,纺织业其次;关税与垂直专业化贸易扩展呈明显的正相关联系;产业规模较小、中小企业居多的部门一般具有较高的垂直专业化程度。     

中国实施绿色GDP的困难与对策

论我国现行缺陷产品召回制度

我国有关缺陷产品召回制度的法律规范或者原则性较强缺乏可操作性、或者位阶较低不具有广泛性、或者针对特定产品适用面较窄。所以,我们应借鉴发达国家的先进经验制定有关缺陷产品召回制度的基本法律和针对特定行业的特别法律,同时建立明确的缺陷产品召回管理体系,以形成保护消费者、维护市场安全与稳定的健全的法律制度和运行机制。
