中文摘要：

企业是否选择自主研发及其自主研发选择的动力与制约因素是自主创新的重要问题之一．将自主研发选择影响因素归纳为主观与客观共五个因素——创新压力、创新信心、创新氛围、研发体系、创新外部依赖，通过175家企业自主研发问卷调查，应用Logistic回归模型实证分析了上述影响因素对企业自主产品研发和自主技术研发选择的作用，并比较两者间差异．实证结果表明，两种研发选择既受共同的因素影响，也存在各自特殊的影响因素；企业从自主产品研发到自主技术研发转变过程中，各影响因素的作用是动态变化的．

英文摘要：

The drivers and restrictions of organizational indigenous R＆D choices is an extremely important issue for indigenous innovation research. It finds five influential factors, including pressure, confidence, environment, R＆D system and the external dependence of the innovation activities. Through a survey on 175 enterprises about their indigenous R＆D, it empirically analyzes the impacts of five factors on the indigenous product R＆D and technology R＆D, and compares their difference. The results indicate that indigenous product R＆D and technology R＆D have common factors and special factors. The impacts of factors dynamically change during the transformation process from indigenous product R＆D to technology R＆D.
