A process model of entrepreneurial venture creation

The process model of entrepreneurial venture creation developed in this paper is based on interviews with entrepreneurs who started twenty-seven business in a range of industries in upstate New York. The venture creation process described here is an iterative, nonlinear, feedback-driven, conceptual, and physical process.The model includes internally and externally stimulated opportunity recognition, commitment to physical creation, set-up of production technology, organization creation, product creation, linking with markets, and customer feedback. For analytical convenience, the process has been divided into the opportunity stage, the technology set-up and organization-creation stage, and the exchange stage. Business concept, production technology, and product are respectively the core variables representing the three stages.Entrepreneurs introduce differing amounts of novelty at each core variable during venture creation, and the varying amounts of novelty qualitatively distinguish one kind of entrepreneurship from another.For the researcher, the model suggests a better method for specifying samples of entrepreneurial firms. It shows how studies on the context of venture creation can be more specific, and proposes that novelty at the core variables be operationalized as a step toward defining the entrepreneurial content of ventures.For the prospective entrepreneur, the model will serve as a useful road map. It will alert the entrepreneur to the strategic issues at each stage in the venture creation process, particularly when introducing significant novelty at any of the core variables.     

我国商品期货市场弱式有效性实证研究

现以我国三个商品期货市场的主要交易品种合约为研究对象,运用单位根检验、序列相关检验对期货收益率进行实证分析,其结果表明我国所有期货品种的价格时间序列满足一阶单整过程,棉花、铜期货品种的收益率时间序列服从随机游走过程,而大豆、豆粕、天胶、硬麦四个期货品种的收益率时间序列存在3阶自相关,我国商品期货市场整体上尚未达到弱式有效。     

绿色供应链管理理念初探

在新的环境时代,工业生产和环境保护能够共同协调发展。现今的公众已不仅要求企业对产生的废物进行处理,更要求企业减少产生污染环境的废物,而且要求企业进行绿色管理,生产绿色产品。面对这种挑战,第一步要做的就是重新定义供应链管理,把环境问题融入整个供应链过程。     

偏苯三酸酐的生产应用及市场前景

偏苯三酸酐是一种重要的有机化工原料,主要用于生产粉末涂料、环氧树脂固化剂、偏苯三酸酯类增塑剂、聚酰亚胺绝缘漆等,其生产方法主要有硝酸氧化法、液相空气氧化法和间二甲苯法3种。2008年世界偏苯三酸酐的总生产能力约为31．0万t／a,消费量约为23．0万。中国偏苯三酸酐的生产能力约为10．5万t／a,消费量约为3．3万t／a。预计到2010年中国偏苯三酸酐的消费量将达到约4．1万t,产能已经严重过剩,切不可盲目扩建产能。

Computer ownership and home usage: the case of Malaysia

The multi‐functionality of computers and the increased accessibility of the Internet have created a demand for computers at home which was previously concentrated in offices. Using the Heckman two‐step model and by combining socioeconomic factors and insights from Becker's theory on allocation of time in the household with information system theories, it was found that: (i) household allocation of resources; (ii) age and gender; and (iii) household social environment are significant in determining computer purchase decisions and its extent of usage in households in Malaysia, a developing information, communication and technology country. Responses collected from 500 computer users were used in the study. Unlike most household technologies, the results also suggested that despite the multi‐functionality of computers, it was perceived as a technology that facilitates the consumption process more than the production process.     

TECHNICAL CHANGE IN PRODUCTION PROCESSES OF THE SEQUENTIAL INTERINDUSTRY MODEL

Transient processes important to understanding technical change are modeled using a time-varying version of the Sequential Interindustry Model, SIM. A simple process of technical change is explored, where a new production technique replaces an old one for one of an industry's production processes. Using several measures internal and external to the industry the model can help in understanding the complex processes of technical change, point to difficulties in their analysis, and suggest guidance to further examinations. An earlier version of this paper was presented at the Eighth International Conference on Input-Output Techniques, Sapporo, Japan, July 1986.     

低碳经济与我国国际分工地位:思路与对策

低碳经济作为一种可持续的经济发展模式为我国经济的结构升级和国际分工地位的提升创造了新的机遇。为此,在国内的经济发展中,不仅要从低碳生产的角度做好节能减排,而且要从低碳消费入手把握全球生产生活方式变革所衍生的巨大需求;在对外的经济政策中,要以"共同但有区别的责任"原则为基础,结合对发达国家作为主要的全球消费者和工业排放的历史责任者的定位,为我国低碳经济的发展和扩张争取更多的时间和空间。
