Analysing Materials and Energy Flows in an Industrial District using an Enterprise Input–Output Model

Recent approaches to sustainable development leave much room for policies at a local level. In fact, it is becoming evident that targets such as increasing resource productivity, preserving natural cycles, or extending the present level of welfare, are best pursued within the confines of a local area. In particular, environmental changes are best brought about by considering local systems of firms as cornerstones of cooperative strategies and using data on materials and energy use in physical terms. In this paper, an enterprise input–output model is developed for an industrial district, i.e. a local group of firms specialized in the production of a single final output. The model allows for a detailed quantitative analysis of materials and energy flows and the consequent generation of waste and pollution. As a planning tool, the model may be used to evaluate alternative scenarios, such as the possibility of re- using waste taking account of sustainability requirements. An empirical case study applies the model to an industrial district in Southern Italy producing leather sofas.

Empirical Investigation on China＇s Private Enterprises Performance Change Before and After Listing

This paper evaluates the performance change of the private enterprises listed on China＇s two exchanges during 2 years before and after listing in the period of 1996-2001. It is concluded that earning ability, real sales and financing are significantly improved, while only profitability decline a little bit after the private firms listed. In addition, we find that IPO private firms have appreciably better performance than that of BS ones as well as the financing condition becomes finer, which is relative to both the attributes of the private enterprises and Chinese regulatory rules. Therefore, we figured out that the outcome of private firms listing is positive, and China＇s economic reform will be a step-by-step process.

An investigation of transformation-based prediction interval for the Weibull median life

Statistical inference based on the Weibull distribution, a distribution widely used in reliability and survival analysis, is usually difficult as it often involves numerical computation and approximation. However, this distribution can be transformed to near-normality by a simple power transformation. Based on this transformation, a prediction interval (PI) for its median can be easily constructed through an inverse transformation. The procedure for selecting the best power transformation through minimizing Kullback-Leibler information is described. The property of this transformation-based PI is investigated. Simple correction factors are also proposed. It is shown that the transformation-based PI with corrections performs well, irrespective of the sample size and parameter values. Simulation results show that the new PI generally outperforms the existing PI. Numerical examples are given for illustration.     

论企业的品牌战略——以商标法为视角

在世界经济一体化进程中,我国企业知名品牌数量少、档次低,影响其发展壮大,促使其树立品牌战略。从商标法的角度看,品牌设计要符合法律的规定,考虑到不同地区的风俗习惯,尽量使用强商标。商标要及时注册和续展,使用联合商标和防御商标,以防止商标被境外抢注;同时,也要注重商标管理和保护,保证企业的品牌战略顺利实施。

美、德农业社会化服务提供的启示

美国的农业社会化服务主要由三个部分组成：农业公共服务体系、集体农业服务体系和私人农业服务体系。公司＋农场、公司＋农户以及合作供销是美国农业社会化服务的三种形式。德国的农业社会化服务体系在于农业专业合作社组织的成功发展,尤其是健全的农村金融服务体系,由一个具有三级层次结构的分权型组织组成,通过立法和提供一些优惠政策,政府在服务体系中起了重要作用。我国农业社会化服务体系的组成和服务形式与美、德十分相似,在推动农村经济发展方面却有一定差异,美国和德国农业社会化服务的经验对中国农业社会化服务的发展具有重要启示。
