中文摘要：

在纵向关联市场中,买方势力和资产专用性是影响企业技术创新的重要因素。本文以我国汽车工业2000-2008年统计数据为样本,利用面板数据模型对买方市场势力、资产专用性与技术创新的关系进行了实证检验,研究结果表明：技术创新行为不仅取决于企业自身所处的市场条件,还与作为买方的下游行业市场竞争状况有关,买方市场势力的增强有利于上游企业技术创新活动的开展;下游企业的资产专用性对上游企业技术创新具有显著的负效应,固定资产比例越高,研发投入越少。此外,较快的市场需求增长率和买方技术能力对技术创新具有积极影响,上下游行业之间较为对等的市场势力会阻碍技术创新。

英文摘要：

Buyer power and asset specificity are important factors of affecting technological innovation in vertical market.Taking Chinese automobile industry statistics from 2000 to 2008 as samples,this paper empirically tests the relationship between buyer power,asset specificity and technological innovation through the panel data model.The results show that technological innovation depends not only on supplier market conditions,but also on the competitive conditions of downstream industry.Buyer market power helps promote upstream technological innovation activities;buyer asset specificity has a significant negative effect on their own technological innovation,the higher the proportion of fixed assets is,the less RD inputs will be.In addition,buyer technological capabilities and the rapid growth of market demand have a positive impact on technological innovation,while equal market power between upstream and downstream industries is an obstacle to technological innovation.
