The purpose of this paper is to explore the correlations among entrepreneurial environment, market-oriented strategies, and entrepreneurial performance.

Entrepreneurial environment is measured by institutional environment and industrial environment. A survey of 176 large Chinese automobile firms is conducted. The structural equation model is applied to perform analysis.

The uncertainty of the institutional environment is positively related with market-oriented strategies and market-oriented strategies are positively related with firms’ performance. The stronger the uncertainty of the industrial environment is, the larger impact that market-oriented strategies have on firms’ performance will be. There is no distinct positive relationship between the uncertainty of industrial environment and firms’ market-oriented strategies. The hypothesis, that the stronger the uncertainty of institutional environments is, the larger the impact that market-oriented strategies will be on firms’ performance, is not supported.

In terms of research design, this paper does not select survey samples randomly. This paper only takes institutional and industrial environments into consideration while the environmental characteristics are omitted.

This paper expands entrepreneurship research by integrating previous studies. Findings in this paper are helpful for firms in emerging countries to implement “going abroad strategies,” to start up new businesses in other countries, and to achieve the goals of improving competitiveness and integrating with international firms.

The purpose of this study is to determine the tribological behavior and wear mechanism of a polytetrafluoroethylene (PTFE)/polyester (PET) fabric composite for application as a self-lubricating liner suitable for high-speed and low-load friction conditions.

The effects of different loads and sliding speeds on the friction coefficients and wear characteristics of the composite were studied using reciprocating friction tests. Scanning electron microscopy, extended depth-of-field microscopy, and energy-dispersive X-ray spectrometry was used to analyze the worn surface morphology, wear depth and elemental content of the lubrication films, respectively.

The friction coefficient curves of the composites presented a long-term steady wear stage under different sliding conditions. With increasing sliding speed, the friction coefficient and wear depth of the composite slowly increased. The film-forming mechanism of the composite revealed that the PTFE/PET ply yarn on the composite surface formed complete PTFE lubrication films at the initial sliding stage.

The PTFE/PET fabric composite maintained good friction stability and high-speed adaptability, which demonstrates that the composite has broad application prospects as a highly reliable self-lubricating bearing liner with a long lifespan.
