技术中介在技术交易服务中是否存在下沉倾向——基于买方选择视角的验证

技术要素转移与交易对技术中介有较强的依赖性，而技术中介的存在能够有效降低交易过程中的信息失衡，为买方交易提供必要支持，技术中介服务直接影响技术交易效率。当代技术中介服务已经形成较大规模，提供服务的种类也较为全面，整体上适应了技术市场发展需要。但是，由技术中介参与的大量交易都存在低端化倾向，据此提出中介服务下沉化假设，并构建选择影响因素模型。通过对买方企业数据的采集与回归，发现无论是全样本还是分类样本均有效验证了主要假设变量。因此，为保障技术中介合理发展，从政策层面应重点关注如何提升服务质量，使其服务于中高端技术交易需求。

Does the Technology Intermediary have the Tendency of Sinking in the Technology Transaction Service: Verification based on the Perspective of Buyer Selection

The transfer and transaction of technology elements have a strong dependence on technology intermediary.The existence of intermediary can effectively reduce the information imbalance in the transaction, and provide the necessary support for the buyer in the transaction.The quality of technology intermediary service directly affects the efficiency of technology transaction.The contemporary technology intermediary service has formed a large scale, and the types of services provided are relatively comprehensive, which generally meet the needs of the development of the technology market.However, according to the actual statistical data, it is found that a large number of transactions involving technology intermediaries tend to be low-end.Based on this, this paper puts forward the hypothesis of intermediary service sinking, and constructs the model of influencing factors of selection.Through the data collection and regression of the buyer's enterprises, it is found that both the full sample and the classified sample effectively verify the main hypothesized variables.Therefore, in order to ensure the reasonable development of technology intermediaries, the policy level should focus on how to improve their service quality and make them serve the needs of high-end transactions.
