拓展以质量信号为主要内容的市场信号理论和以技术特征为主要内容的知识转移理论，分别引入技术可供性和技术特征作为中介变量和调节变量，选取2010-2020年A股上市的313家制造类高新技术企业为样本，运用多元线性回归等方法，实证研究质量信号对创新绩效的影响机理。研究发现：质量信号与技术可供性的增强有利于促进企业创新绩效的提升；随着质量信号的加强，技术可供性也有所增强；技术可供性在质量信号与创新绩效之间起中介作用；技术宽度、技术深度以及技术重叠度等技术特征对创新绩效具有倒U型影响，并且负向调节质量信号与创新绩效之间的关系。进一步地，从所有制、区域以及创新行为等视角就质量信号与创新绩效的关系展开异质性分析，即相对于非国有企业以及中西部地区企业，质量信号增强更有利于促进国有企业与东部企业的创新绩效；相对于突破式创新，质量信号增强更有利于推动企业展开渐进式创新。为促进企业创新绩效，提出重视质量信号的发送与接受，提升技术可供性，有效把握与预知技术创新或变革所可能带来的市场效果与认可度，保持适当的技术宽度、技术深度以及技术重叠度等对策建议。

Expand the market signal theory with quality signal as the main content and the knowledge transfer theory with technical characteristics as the main content, introduce technology availability and technical characteristics as intermediary variables and regulatory variables respectively, select 313 manufacturing high-tech enterprises listed in A-share market from 2010 to 2020 as samples, and use multiple linear regression and other methods to empirically study the impact mechanism of quality signal on innovation performance. The research finds that the enhancement of quality signal and technology availability is conducive to the improvement of enterprise innovation performance; With the strengthening of quality signal, the availability of technology has also been enhanced; Technology availability plays an intermediary role between quality signals and innovation performance; Technological characteristics such as technology width, technology depth and technology overlap have an inverted U-shaped impact on innovation performance, and negatively regulate the relationship between quality signals and innovation performance.Further, from the perspective of ownership, region and innovation behavior, we analyze the heterogeneity of the relationship between quality signal and innovation performance, that is, compared with non-state-owned enterprises and enterprises in the central and western regions, quality signal enhancement is more conducive to promoting the innovation performance of state-owned enterprises and eastern enterprises; Compared with breakthrough innovation, quality signal enhancement is more conducive to promote enterprises to carry out incremental innovation. In order to promote the innovation performance of enterprises, it is proposed to pay attention to the sending and receiving of quality signals, improve the availability of technology, effectively grasp and predict the market effect and recognition that technological innovation or change may bring, and maintain appropriate technological width, technological depth and technological overlap.
