新型轮对检测仪表

目前,机务段用以测定机车轮对轮箍磨损的检测工具一般都为机械检测工具,例如量规和卡规等等.为了对轮对的滚动面(踏面)作有效而精确的检测,国立乌拉尔交通学院与传感器信息工艺学院的专家们研制出了1种新的仪表.

制造是汽车工业的重要环节，更是汽车业利润的重要来源之一。中国汽车工业协会助理秘书长杜芳慈日前指出：“作为制造业的汽车产业，大部分利润应该来源于制造环节。而不是汽车金融和售后服务等环节。同时，应该把5％确定为整车制造的利润率红线。低于这个比率，汽车研发、生产将很难保证。”

Factors that promote innovation in shipping companies

This study seeks to identify factors that promote innovation in shipping companies. The study is based on an empirical investigation of 63 companies headquartered in Norway. The results imply that organizational and interorganizational variables are important to innovation. Three aspects of innovation are focused on: (1) service/product innovations, (2) market innovations, and (3) production method innovations. The explanatory variables that are applied in this study capture between 13–51% of the variability of the measures of innovation. The results indicate that an explicit strategy that promotes innovation is very important for the actual level of innovation within shipping companies. In management literature, it is often assumed that organic organizational features like decentralized decision-making promote innovation. The opposite features are assumed to restrain innovation. However, the results do not support these basic assumptions. For example, it seems to be important that managers make precise decisions in order to promote innovation.     

The performance effect of innovation in shipping companies

The aim of this study is to investigate how innovation contributes to company performance in Norwegian shipping and to extend our knowledge concerning what organizational and inter-organizational factors influence innovation in shipping firms. The study is based on a survey of 46 Norwegian shipping companies. We find that innovation contributes to firm performance. We also find that a conscious strategy, strategy involvement, external relationships, especially market relationships, and productivity slack have a significant positive effect on the degree of innovation. The results are dependent upon the companies’ degree of differentiation and the type of innovation.
