中文摘要：

市场是否认同企业的研发投入价值直接影响到企业R＆D投入的动机和效果，进而影响到企业的可持续发展。本文通过理论和构建多元线性回归模型，分别研究了产品市场和股票市场是否认同企业的研发投入价值。实证结果表明：（1）在产品市场上，消费者认同企业的研发投入价值；高新技术行业的企业与非高新技术行业的企业所获得研究发投入的市场效果不同，前者获得了更高的销售毛利率，有更大的市场认同度；相比第一大股东为国有控股公司，消费者对第一大股东性质为非国有控股企业的研发投入价值有更大的认同度。（2）在股票市场上，投资者对公司披露的研发投入价值并没有得到显著性认同的证据，这在一定程度上反映了我国股票市场支持企业成为自主创新主体的动力不足。

Whether the market accepts the value of business investment in R＆D directly affects motives and the effects of R＆D expenditure, thereby affecting the sustainable devel-opment of enterprises.

Enterprise＇s core competitiveness and competitive advantage in the market needs more prod- ucts with high technical content or update the technology of existing products by much R＆D activity. This process implicates in turn that in the R＆D innovation decision-making, we must consider the market recognition to develop new products that consumers identify the level of R＆D in order to reduce market risks, forming an effective mechanism of R＆D cycles to make investment in R＆D a positive interaction with the market recognition. （2） There is a significant different economical efficiency in product market between hightech and non-high-tech enterprises, the former receive a higher gross profit ratio and greater market acceptance. The results show that high-tech enterprises in R＆D investment have a significant difference statistically and R~D intensity has a greater contribution to gross profit ratio than non-high-tech enterprises. In other words, the products market is the place that consumers are inclined to more high-tech enterprises and recognize the value of R＆D, willing to pay higher prices. This result implicates that the higher the technological content of the enterprise,
