中文摘要：	随着经济全球化不断推进，科技快速发展，“自主创新”已经成为国家面对日渐激烈的竞争时的国家竞争力的核心。高科技产业作为一种以高新技术为主要投入的产业，是我国建设创新国家、构建创新体系中的重要主体，提高高科技行业企业的研发能力，对企业乃至国家的战略发展都有重要意义。近年来，我国研发支出快速持续增长，但是研发强度仍然较低，有待进一步提高。许多研究分析了制约我国高科技企业R&D投入的因素，其中之一的融资约束无疑是制约研发投资不足的关键因素。知识经济时代，知识产权已经成为企业获取市场竞争力的焦点，不同地区的知识产权保护水平不同。知识产权保护水平薄弱的地区，企业的知识产权资产不能够得到强有力的保障，企业会因为顾忌信息披露带来的侵权风险，而不愿意将其技术情况和项目进展披露给外部资金提供者，造成企业外部融资成本高高于企业内部融资成本的融资约束，制约了企业的研发投资。因此，本文以融资约束作为中介变量入手分析影响路径，探讨地区知识产权保护水平对我国高科技企业研发投资的影响。 首先，本文梳理和回顾了知识产权保护水平、融资约束和高科技企业研发投入的相关文献和研究。在此基础上推导出知识产权保护水平对高科技企业研发投入影响的理论路径及融资约束在其中起到的中介作用。最后以2011-2014年间我国高科技企业为研究样本，进行实证设计和结果分析，检验了知识产权保护水平与融资约束、融资约束与高科技企业研发投入、知识产权保护水平与高科技企业研发投入的相关关系以及融资约束的中介作用。 研究结果表明：（1）知识产权保护水平与高科技企业研发投入显著正相关，即提高地区知识产权保护水平能够促进高科技企业研发投入的增加；（2）增强地区知识产权保护水平能够缓解高科技企业的融资约束，两者呈负相关关系；（3）融资约束与我国高科技企业研发投资强度之间存在负相关关系；（4）提高地区知识产权保护水平能够缓解高科技企业面临的融资约束，进而促进高科技企业研发投入的增加。
英文摘要：	With the economic globalization, the rapid development of science and technology, “independent innovation” has become the core countries in the face of the increasingly fierce competition of national competitiveness. High-tech industry as a high-tech industries as the main investment is the construction of national innovation, build the important subject in the innovation system, improve the ability of research and development of high-tech industries and enterprises, to the enterprise and even the national strategic development have important significance. In recent years, R&D expenditure in China sustained rapid growth, but the research strength is still low, needs to be further improved. There are many factors caused by the R&D of China's high-tech enterprises, inadequate investment, financing constraints is undoubtedly one of the key factors restricting R&D investment. In the era of knowledge economy, intellectual property has become the focus of the market competitiveness of enterprises to obtain, as a protection system of intellectual property rights protection and innovation output. Now it has become tools of technology innovation competition activities, affects the output of innovation as the main body of research and development of enterprise benefit distribution. Level of intellectual property protection is weak, the intellectual property assets of enterprises can not get strong support, enterprises will because scruples about information disclosure bring the risk of infringement, but do not want to disclose the technical situation and progress of the project to the outside capital providers, cause and external financing cost higher than internal financing cost of financing constraints, restricted the enterprise R & D investment. Therefore, based on the theoretical analysis of financing constraints as a path, to explore the influence of regional intellectual property protection level of the high-tech enterprise in China R&D investment. Firstly, this paper reviews and comments on the level of intellectual property protection, financing constraints and the related literature of R & D investment in high-tech enterprises. On this basis, the theoretical path and the effect of the level of intellectual property on the R & D investment of high-tech enterprises are derived. Finally 2011-2014 years of high-tech enterprise of our country as the research sample, empirical design and results analysis, test the level of protection of intellectual property rights and financing constraints, financing constraints and high-tech enterprise in R & D investment, the level of protection of intellectual property rights and high-tech enterprise R & D investment intermediary role in the relationship and financing constraints. The results of the study show that: (1) enhanced regional intellectual property protection level to ease financing constraints for high-tech enterprises. Both were negative correlation; (2) financing constraints and China's high-tech enterprise R & D investment showed a significant negative correlation; (3) the level of intellectual property protection and hi tech enterprise technology R & D investment has a significant positive correlation, that is, to improve regional intellectual property protection level can promote the increase of investment in research and development of high-tech enterprises; (4) improve the regional intellectual property protection level to ease the financing constraints faced by high-tech enterprises, and promote high-tech enterprise development investment increased.
