贸易自由化对环境污染影响的实证分析

采用Panel-data模型方法,研究贸易自由化对环境污染的影响。通过建立联系贸易与环境污染的一般均衡模型,将贸易的环境效应分解为规模效应、结构效应、技术效应,并用我国各省的二氧化硫数据进行检验。结果显示,规模效应加剧我国环境的恶化,而结构效应和技术效应改善我国的污染水平。结论是贸易自由化有利于我国环境保护。     

金沙古史探微

在成都摸底河两岸发现的金沙遗址是历史上开明王朝生活于此的文化遗存。开明族富于治水经验，他们进入成都平原后很快就取代了出自西山的古蜀族．建立了金沙古城．因此这里并无望帝于丛帝禅让的情况。而古蜀族地位逐渐下降．其沦为二等公民殆无疑义。金沙古城与十二桥遗址相近．应是同时代的双子城。金沙时代气候温暖潮湿。其自然环境与三星堆时代迥然不同。距今约2300年前，金沙古城毁于洪水，不久强秦入侵．开明族统治结束．亦即古蜀最后覆亡。     

Boards of directors in family firms: a generational perspective

The purpose of this study is to advance the understanding of boards of directors in family firms. Building on generational changes in family attributes, we argue that firms in a different generational phase have different governance needs and characteristics. With regard to board task needs, the empirical results indicate a convex generational evolution in the need for board advice, and a rise over the generations in the need for board control. With regard to board composition, we find that the likelihood of having an outside director on the board has a convex generational trend. This relationship seems to be fully mediated by the firm’s board task needs. Furthermore, the number of family directors seems to increase over the generations. This study demonstrates that it is important to consider the generational phase of the family firm in order to understand its governance system.

中国纺织服装出口企业贫困增长源于对比较优势战略的过分依赖

比较优势战略,从静态角度看,有利于一国充分发挥自己的优势,促进经济的健康发展;但从动态看,众多国家同时采用这一战略,必然导致合成谬误的产生。即专业化导致生产能力快速增长,产品供应超过需求,市场价格下降,销售越多,收益反而下降,其结果就是企业的贫困增长。发展中国家必须采取有力措施,创造良好的制度环境,使企业能够摆脱对价格竞争路径的过度依赖,从技术进步与自主品牌的建设中获得收益,而不能完全按照自由主义的比较优势理论来发展相关产业与对外贸易。     

Using diffusion models to forecast market size in emerging markets with applications to the Chinese car market

Marketing managers have to forecast the market size and this forecast guides strategic decisions whether to continue exporting, open new factories or expand existing production operations. Forecasting sales and the market size is a challenging task; even more so in emerging markets where data is limited and the market demand is changeable. This research proposes a novel approach that applies diffusion models using car ownership data to forecast car sales. Car ownership data may be easier to access than sales data in emerging markets but marketing managers are more interested in the sales forecast. Researchers propose using diffusion models to forecast the adoption of new products or products which are new to consumers in a market. This research demonstrates that marketing managers can use diffusion models to predict car sales in China where cars are new products to most consumers in this market. Since the majority of car buyers in China are first time buyers, car manufacturers and retailers must also forecast when the market composition will change. This effectively means predicting when first time car buying will start to slow down and repeat/replacement purchase or second hand car purchase will become more important. To forecast both sales and market composition change, marketing managers must choose a robust model. Managers want insights from models that have been tested robustly especially in less stable market conditions. In this context, this study illustrates the value of using a rolling forecast instead of a fixed horizon approach when comparing and choosing which model to use to forecast both sales and market composition change for the Chinese car market.     

经济转型背景下日本贸易技术结构的演进研究——基于1960-1988年数据的实证分析

贸易结构是一国产业结构的反映,对一国产业结构也会带来一定的影响。依据经合组织的技术密集度标准,将日本的进出口商品进行分类。在此基础上,分析了日本贸易结构技术构成的演进。研究发现,战后日本的出口结构出现了持续、明显的升级,进口则集中在中技术与低技术产业。随着日本经济的发展,影响贸易结构的因素以及进出口结构之间的关联均发生了明显的变化。     

Last dance or second chance? Firm performance,CEO career horizon,and the separation of board leadership roles

In recent years, many firms have chosen to separate their CEO and board chair positions. Prior research has demonstrated that there are three forms that a CEO–board chair separation can take: apprentice, departure, and demotion. In this paper, we examine the antecedents of these three types. Our results show that the three types of separation each have different profiles in terms of the prior performance of the firm, the independence of the board, and the career horizon of the incumbent CEO. The findings in this paper provide unique insights into the factors that drive boards' structural choices. As questions about board leadership structure become more nuanced and more relevant in both scholarship and practice, a full understanding of these factors will only become more important.
