摘　　要：价格决定和价格竞争是厂商行为理论研究中的重要议题。囿于价格竞争相关微观企业数据获取和测度方面的难度,相关领域还一直缺乏经验证据。本文探索性地基于上市公司数据进行实证,以我国1999—2010年A股上市公司为研究样本,首先实证检验了公司在市场中的相对势力与价格竞争之间的关系,并以此为基础,进一步检验行业层面的结构特征对二者间关系的影响。实证检验结果表明:公司市场占有率越高,即在市场中的相对势力越强,其进行价格竞争的优势越明显;不过,公司所处行业的结构特征会调节二者间关系,伴随行业集中度提高,市场势力较强公司进行价格竞争的优势下降,依据行业集中度分组的检验结果同样支持该发现。本文的研究结论不仅在一定程度上填补了价格竞争微观数据经验研究的空白,而且还丰富了产业组织与微观企业间行为关系的学术文献。Price determinants and price competition are important issues in firm theory. Due to difficulties in accessing and measuring the price competition tendency of a company, there is still little empirical evidence in related research field, This study tries to use public listed firms＇ data to conduct exploratory research, Taking Cbina＇s A share listed companies from 1999 to 2010 as research sample, this paper firstly studies the relationship between firms＇ relative market power and price competition tendency. Based on this, this paper further studies whether industry structure affect this relationship. Empirical results suggest that the higher the market share of a company is, the higher the degree of price competition tendency is. However, the industry structure of a company will moderate this effect. As the industry concentration increases, the price competition tendency of a company with greater market power will decrease. The tests based on groups according to industry structure also support this findilN. Our conclusions not olnly fill the gap in micro empirical evidence of price competition to some extent, but also era-icE the academic literatme on relationship between industry orgalnization and micro firm＇s behavior.
