环境成本内在化对浙江产业国际竞争力影响的实证分析

文章在浙江出口量较大的产业中选取了部分污染产业,将产业分成强污染组和相对较弱污染组,并利用2002-2011年10年的面板数据,进行了环境成本内在化对产业国际竞争力影响的实证分析.分析发现：不论是强污染组,还是相对较弱污染组,其回归结果均显示环境成本内在化对产业国际竞争力在5％水平上显著为负;不同组的影响程度相差较大,强污染组有较大的弹性系数（-8.71）,而弱污染组的弹性系数仅为-1.39.这一结果说明环境管制是影响产业国际竞争力的重要因素,需引起相关部门的重视,并需思考如何更好地刺激理论上正向影响作用的发生.     

我国出口农产品技术含量和附加值的实证研究

随着农业科技的进步,我国出口农产品的技术含量和附加值正不断提高.文章实证分析了不同技术含量农产品的出口情况,测度了不同技术含量农产品的比较优势及出口竞争力,横向比较了出口农产品的附加值.研究表明：我国粗加工农产品、深加工农产品的技术含量和附加值在不断提升,比较优势和竞争力都在不断增强,而传统的衡量方法低估了我国农产品贸易结构的优化程度;持续加大科技投入力度,继续推动农产品精深加工,提升农产品的技术含量和附加值是未来我国农业发展的必然选择.     

Competitive diffusion process of repurchased products in knowledgeable manufacturing

This paper presents a diffusion model to explain the competitive diffusion of the repurchased products in knowledgeable manufacturing. The acute market competition accelerates the products’ improvement, which requires that the manufacturing enterprises be highly capable of rapid reaction by means of knowledgeable manufacturing. To forecast the diffusion behavior effectively enables the realization of knowledgeable manufacturing system (KMS) which targets T (time), Q (quality), C (cost), S (service), and E (environment). Various diffusion models have emerged since Bass model was firstly proposed in 1969. A nonlinear model of the repurchased competitive products is proposed on the basis of the product diffusion analysis. By taking the frequently purchased products as example, the stability of the model is examined in light of the qualitative theory of differential equations and proved by the approximate linearization method. As the qualitative analysis reveals, between the two frequently purchased products competing in the same market, one undoubtedly occupies a fixed market share while the other may finally be eliminated from the market. A special case of the problem is that both products are one-time-purchased. With the corresponding model given, the qualitative analysis shows that either of the products occupies a market share, the size of which is determined by the product’s competitive strength and the new product’s time-to-market. A system dynamics model is then established and simulated by vensim. The result is consistent with that of the qualitative analysis.     

动态区域禁忌匹配策略提高新生换热单元竞争力

在优化换热网络过程中, 有分流节点非结构模型的换热单元会打破初始均匀分布状态向流股上游区域集中, 使得冷热流股入口区域无法生成新的换热单元, 造成结构变异能力下降。本文探究该现象成因及其对进化的影响, 并提出动态区域禁忌匹配策略: 上游区域空节点时允许自由匹配; 当上游区域节点非空时进行上游区间的清空操作, 即将生成节点等效向下游区域进行转移, 从而保障换热单元在上游区域的匹配活力, 增强新生成换热单元在结构进化过程中的竞争力, 促进换热网络结构进化。通过在算例15sp和20sp的应用, 发现该策略能够提升网络结构变异能力。

人文竞争力:体育产业发展的核心动力

文章认为人文竞争力是体育产业发展的核心动力,体育产业自身的企业行为活动,必须是通过先进的生产手段(包括训练、服务等方式)和人文思想,以满足人们对体育的需求,适应社会需要,使人的体质得到提高和人的精神得到塑造.并分别从:体育的主旨;提高人文竞争力和变人文比较优势为竞争优势等三个方面进行了论述.     

Mathematical structure of a bilevel strategic pricing model

This paper is concerned with the characterization of optimal strategies for a service firm acting in an oligopolistic environment. The decision problem is formulated as a leader–follower game played on a transportation network, where the leader firm selects a revenue-maximizing price schedule that takes explicitly into account the rational behavior of the customers. In the context of our analysis, the follower’s problem is associated with a competitive network market involving non atomic customer groups. The resulting bilevel model can therefore be viewed as a model of product differentiation subject to structural network constraints.
