摘　　要：使用苹果公司上游供应商苏州联建科技公司破产案例构建数学模型。模型中考虑了企业垂直关系所涉及的专用资产、买方垄断以及关系资本3个要素。根据模型得到上游企业创新投入随着企业事前专用资产投入的增加而降低;上游企业创新投入随着自身讨价还价能力增强、买方垄断势力度下降、买卖双方关系资本增加而增加4个推论。使用世界银行对中国企业调查数据对推论进行验证。相关系数矩阵分析发现,上游企业创新投入力度与专用资产比例显著负相关、与合作历史以及企业规模显著正相关。上游供应商规模增大背后,买方企业相对垄断势力度的降低和企业相对讨价还价能力的增强将导致上游供应商创新投入增加。OLS统计和稳健性检验发现上游供应商专用资产投资与其创新力度显著负相关;合作时间表示的关系资本与上游企业创新投入显著正相关。This paper constructed a model based on the case of the bankruptcy of SuZhou Lianjian Company,which had been a upstream supplier of Apple Co.The model concerned on the following three elements in the firm's vertical linkage including specific investment,buyer monopoly and relational capital.The model derived the four deductions as follows:The upstream supplier's innovation investment is reduced with the increase of specific investment for the deal and increased with the enhancement of the bargain power,increased with the decrease of the buyer's market power and increased with the accumulation of the relational capital.The paper used the data collected by the World Bank's investigation on Chinese firms to testify the above deductions empirically.From the coefficient matrix this paper finds that the upstream supplier's innovation intensity is negatively related to the specific investment rate and positively related to the cooperation history and upstream supplier firm's size.The larger the size of upstream supplier firm,the relatively smaller the buyer's market power,the relatively larger the bargain power of the supplier and the upstream supplier's innovation investment will be increased.Both the OLS and robust methods find that the upstream supplier's specific investment significantly reduces its innovation investment;the relational capital represented by the cooperation history has a significant relationship with supplier's innovation investment.
