诚信原则是市场伦理道德在民法上的反映,它一方面要求当事人进行民事活动是必须具备诚实善良,守信不欺和公平合理的主观心理和客观行为状态,对当事人的民事活动起指导作用;另一方面授予法官自由裁量权。在当今市场经济条件下,我们需要重新认识诚实信用原则,求它被广泛的市场主体所重视,从而使每一个竞争主体在市场经济中占有永久的位置。 The principle of sincerity is the reflection of the market ethics in the civil law. On the one hand, it requires the parties to carry out civil activities that they must have the honesty, trustworthiness, fairness and reasonableness of subjective psychology and objective behavior and play a guiding role in the civil activities of the parties. On the one hand grant the judge discretion. In today’s market economy, we need to re-understand the principle of good faith, seeking it by a wide range of market players, so that each of the main competition in the market economy occupies a permanent position.
