互联网正在以越来越迅猛的态势改变着我们的生活方式，而投身于互联网行业的各家高科技公司也正在努力不断创造出更多的产品。对于这些公司来说，创新不止是为了生存，它已然成为了互联网本身所具有的存在形态。在本文中，笔者将研究重点锁定在北京某互联网行业的科技公司，以项目团队为单位，从团队层面出发，去探索该家公司内部存在的可能对创新绩效产生影响的不同因素。在团队属性层面上，选取了团队规模和成员加入团队时间异质性两个变量，在团队成员的主观感受层面上，选择了团队认同(Team identity)以及创新支持(Supervisor supportiveness)两个变量，在行为层面，分别采用团队成员和团队领导的创新行为(Work innovation behavior)，来衡量这两个因素可能会对团队创新绩效产生的影响。团队异质性也叫团队多样性，不同指标描述了团队成员中各种不同特征的分布情况。团队认同是指个体在何种程度上通过团队的身份来进行自我定义。如果一个人认同一个团队，他会从身份，评价和情感三个方面来对自己和公司进行紧密的链接。团队成员的创新行为包含从创新想法的产生到创新想法的推进，以及创新想法的实现三个部分。创新是一个过程，需要在团队内不同成员的努力下共同完成。因此，个人创新行为和团队创新绩效不只是单纯的加和关系，在本文中，我们也会对个人行为和团队绩效的关系进行简单探讨。在对前人文献整理的基础上，笔者对本次实证研究提出假设，研究结果得到以下结论：团队认同对于团队创新绩效有正向积极的影响;团队认同与成员加入团队时间异质性产生交互效应，共同对团队创新绩效产生影响;团队领导对创新的支持对于团队创新绩效有正向积极的影响;团队成员的创新行为对团队创新绩效有正向积极的影响;团队成员的创新行为通过团队领导的创新支持而对团队创新绩效产生积极的影响，创新支持作为中介变量起到了影响;相比于团队中其他成员，团队领导的创新行为对团队创新绩效的正向影响更加明显。而由于团队层面的统计样本量偏小，统计的结果不具有足够的说服力，对于研究中提出的以下问题还不能得到完全支持：当团队创新绩效处于较高的水平时，成员加入团队的时间异质性较高;当团队创新绩效处于较高的水平时，团队规模较小。调查对象为某互联网公司的20个在公司中作为核心业务的工作项目团队，共回收有效量表139份，通过调研实施和数据分析，对以上假设进行了一定程度的支持。在后续的研究工作中，还需要对更多的变量，以及多变量共同对团队创新绩效产生的影响进行更为深入的研究。

Internet is changing our way of life increasingly rapidly, and the high-tech companies that engaged in the Internet industry are struggling to create more new products. In this article, the author will study focusing on an Internet industry high-tech company in Beijing, to explore the different factors within the company which may affect innovation performance on the project team level.On the team attribute level, the author selects two variables include the team size and the diversity of the team members’ tenure; on team members' subjective feeling level, selects the Team identity as well as innovation support; the behavior level, the innovation behavior of team members, as well as the Team leader of innovation behavior to measure their potential impact on team innovation performance.Team diversity is to the team members in different distribution characteristics of description. Team identity refers to the extent to which individual self-defined by the identity of the team. If a person identifies a team, he will link himself with team closely from three aspects: the category, evaluation and emotional. Team members' innovative behavior includes from the generation of innovative ideas to the advancement of innovative ideas, and the realization of the innovative ideas. Innovation is a process, which needs different team members to cooperate to complete together. Individual innovation behavior and team performance, therefore, not simply added. In this article, we will simply on the relationship between the individual and team performance.On the basis of previous literature, the author put forward hypothesis, and the result give support to the follow ones:Team identification has a positive impact on team innovation performance.Team identification and the diversity of the team members’ tenure have interaction effects on team innovation performance.the team leader's support for innovation has a positive impact on team innovation performance.Work innovation behavior of the team members has a positive effect on team innovation performance.Innovation support has a mediate impact between the team members’ work innovation behavior and the team innovation performance. Compared with the other members in the team, the impact of team leader’s innovation behavior on team innovation performance is more obvious.For thestatisticalsample size on team levelis small,the survey resultsare notpersuasive enough. Theproposedhypotheses1and2 in study can’t befully supported yet.When the team performance is in the highest or lowest level, diversity of the team member’s tenure is higher.When the team performance is in the highest or lowest level, a team is on a smaller scale.The Investigation includes 20 project teams from an Internet company. A total number of the effective questionnaire is 139. Through the research and data analysis, the hypothesis above are supported to a certain degree. In the follow-up research work, also need to explore more variable, and the impact of multivariate on the performance of team innovation.
