本文通过运用DEA的C2R模型和DEA交叉评价方法对上市的具有比较典型代表意义的15家房地产公司进行评价,发现其中大部分位于中间规模的房地产行业都具有比较高的DEA效率值,而规模很大的企业则存在着一定的资源浪费,规模小的几家企业则远没取得行业平均收益率,本文对此展开分析并提出了些解决问题的建议。 相似文献

This paper presents an indicator-based methodology to identify lead markets in the European automotive industry. The lead market approach tries to explain why certain countries are better positioned than others for developing and launching new products. While much research stresses the role of excellence in technology and interaction among users and producers, the lead market approach focuses on the role of demand characteristics. Based on the concept of innovation design, a lead market is defined as a country where customers prefer that design which subsequently becomes the globally dominant design. We use an indicator-based approach which has been successfully employed for individual products as well as for various industries in order to identify lead markets in the European automotive industry. Employing five lead market factors, our results show that the EU is by far no homogeneous market for automobiles and national markets differ considerably in their lead market potential. The German market is found to be most promising to serve as a lead market, while other European countries with a strong automotive tradition like France, Italy, the UK, and Sweden score lower. Our findings suggest that firms from the automotive industry should exploit this diversity of market characteristics within Europe when developing and launching new products. 相似文献

This paper deals with the question of how upgrading of the symbolic and synthetic knowledge bases takes place and, by doing so, we contribute to the upgrading literature by linking upgrading with the concept of the differentiated knowledge bases. We discern a number of upgrading mechanisms, and based on empirical evidence from the construction industry and the automotive industry in China, we show that the main upgrading mechanisms for symbolic knowledge include “learning-by-interacting in project teams” and “monitoring”, while upgrading of synthetic knowledge takes place via “technology transfer” and “learning-by-doing and-using”. “Mobility” and “on-the-job training and learning in Transnational Corporations” are the main upgrading mechanisms contributing to the development of both knowledge bases. 相似文献

The healthy and stable development of energy efficiencies in existing buildings cannot be separated from effective policy operation, and evaluating policy effectiveness contributes to scientifically-sound government decision-making. This paper creates an evaluation index system and a grey comprehensive evaluation model for policy effectiveness for energy efficiency in existing buildings using three dimensions: 1) the effect of the policy itself; 2) the administrative effect of the policy; and 3) policy implementation effects. It chooses the government’s subsidy policy and preferential tax policy at market cultivation stage for its empirical comparative evaluation. The evaluation indicates that the former is more effective. Finally, it puts forward policy development suggestions from the perspective of: 1) clarifying incentive object; 2) broadening incentive scope; 3) increasing incentive intensity; and 4) innovating incentive mode. 相似文献

汽车空调HVAC总成的气动噪声是汽车空调系统主要噪声来源之一。本文分析了HVAC总成的气动噪声的产生机理,并对某车型HVAC总成的气动噪声表现进行了性能改进。建立了HVAC内部流场仿真模型,并通过修改空调分配箱壳体与鼓风机蜗壳的结构型线,调节模式风门的位置来优化内部流场。结果表明:优化后HVAC总成的气动噪声表现明显优于原状态;实车上使用频次较高的吹面、除霜模式下的噪声声压级,相比原状态分别降低2.3 dB(A)、3.3 dB(A),降噪效果显著。 相似文献
