The Relationship between the Firm Size and the Quantity of Accountants Employed by the Firm： An Analysis of the 436 Listed Firms in the Chinese Shenzhen Stock Exchange

There are 9.56 million accountants in China, who are working in different size firms and nonprofit organizations. The objective of this article is to examine the quantitative relationship between the firm size and the quantity of accountants working for the firm. In this paper, the employees, sales revenues, and total assets in a firm are employed to measure firm size. The authors collect and analyze the data of 436 listed firms from the Chinese Shenzhen Stock Exchange. The result of this study indicates there is a positive relationship between the firm size and the quantity of accountants employed by the firm. The study also establishes the multiple regression equation, which can be used to predict the quantity of accountants of listed firms. And it provides a way to predict the quantity of accountants of legal organizations.

基于恒定市场份额模型的中国林产品出口分析

针对1992~2004年中国林产品出口规模的变动特征,采用恒定市场份额模型,对影响中国林产品出口规模变动的因素进行了分析。结果表明:中国林产品的出口明显受其产品竞争力的影响,提高林产品的竞争力对促进林产品出口具有非常积极的作用,世界林产品贸易规模的扩大和商品出口构成的优化对中国林产品的出口产生了正面影响,而市场分布效应则是负的。同时,提出通过提高林产品的竞争力、增加中国人造板的出口以及积极开拓新市场来促进中国林产品的出口等建议。

Disaggregation and consolidation of imperfect quality shipments in an extended EPQ model

We consider a standard economic production quantity (EPQ) model. Due to manufacturing variability, a fraction P of the produced inventory will have imperfect quality, where P is a random variable with a known distribution. We consider a 100% inspection policy and further assume that the inspection rate is larger than that of production. Thus, all imperfect quality items will be detected by the end of the production cycle. For such an augmented EPQ model, we first derive the new optimal production quantity assuming that the imperfect quality items are salvaged once at the end of every production cycle. Then, we extend this base model to allow for disaggregating the shipments of imperfect quality items during a single production run. Finally, we consider aggregating (or consolidating) the shipments of imperfect items over multiple production runs. Under both scenarios we derive closed-form expressions for both the economic production quantity and the batching policy, and show that our desegregation/consolidation schemes can lead to significant cost savings over the base model.     

再论包含两类技术创新的内生经济增长模型

目前关于产品种类扩大型和熊彼特质量改进型的技术创新内生增长模型均较完善,但缺乏同时纳入两类技术变革的内生增长模型。本文构建了包含两类技术创新的内生增长模型,综合分析了技术进步导致经济增长的内在机制,并利用全素生产率核算方法进行了测算。测算发现在1995年至2009年期间政府有意识的技术研发投入对中国经济增长的贡献率上升了12个百分点,但与发达国家相比仍有较大差距,需政府进一步加大研发投入力度,同时加大科技成果转化为经济效益的强度。
