【摘要】 对正处于新一轮跨越式发展关键时期的中国来说,创新是推动经济结构调整和增长方式转变的关键环节,是实现社会经济持续协调快速发展的核心动力。企业作为创新体系的主体,其创新活动在提升国家创新能力过程中具有重要战略地位。但国家相关部门统计数据显示,尽管我国企业的R&D投入强度保持一定上升趋势,但与发达国家仍有较大差距,而且对外技术有较高的依存度,国内拥有自主知识产权核心技术的企业极少。这都表明我国企业创新能力还较为薄弱。然而,企业创新活动会受到其自身经济特性的影响,市场失灵的存在使得市场机制未能实现资源的最优化配置,因此政府有必要加以干预,为激发企业的创新动力提供良好的政策环境。税收激励由于更倾向于利用企业和市场的力量,具有普惠性,因而被世界各国政府普遍采用。本文从企业微观角度研究税收激励政策对创新绩效的影响,进一步丰富我国有关企业创新的研究的同时,能够为政府政策制定提供合理参考,更为重要的是,可以使企业在经营实践过程中有针对性的选取适宜的优惠措施服务于企业创新活动。根据研究主题,本文采用文献资料法、内容分析法、问卷调查法及统计分析法,依照提出问题、分析问题和解决问题的思路,从如下四个方面就税收激励政策对企业创新绩效的影响进行研究：(1)通过文献与资料的梳理,回顾以往学者对税收激励政策和创新绩效的相关研究,了解我国企业创新活动现状及问题,明晰我国税收优惠政策的发展历程与特征；(2)基于经济增长理论分析税收激励政策对创新投入及其对创新绩效的影响机理,构建相应概念模型；(3)采用问卷调查方式收集数据,对税收激励政策、创新投入和创新绩效量表进行信度和效度检验,运用逐步回归分析方法对理论模型和研究假设进行检验,并运用上市公司公开数据进一步论证；(4)通过对我国与主要发达国家现行税收优惠政策的对比分析,并结合实证数据检验结果,提出提升我国创新税收政策激励效应的建议。本文从创新投入的视角切入对税收激励政策与企业创新绩效之间的关系展开研究,建立了“税收激励政策——创新投入——创新绩效”的概念模型,并提出税收激励政策通过创新投入中的资金投入和人力投入对企业创新绩效产生影响的各项理论假设。本研究通过对我国301家企业问卷调查数据以及281家上市公司公开数据进行实证检验,分析结果表明税收激励政策能够影响企业对创新活动的资金与人力投入,并进而对创新绩效产生作用。主要研究结论如下：(1)税收激励政策对企业创新活动的资金投入与人力投入有显著的正向效应。从相关系数的大小来看,税收激励政策对企业的人力投入有更强的激励效应。(2)企业对创新活动的资金与人力投入对创新绩效有显著的正向效应,说明充足的资金支持是企业实施创新的关键要素,而企业对员工人力资本的投入同样是开展创新活动的重要因素。(3)创新投入是税收激励政策影响企业创新绩效的完全中介变量。税收激励政策与企业创新绩效之间具有显著的正相关关系,而在加入创新投入变量后,创新投入与企业创新绩效之间仍旧具有显著的正相关关系,而税收激励与创新绩效之间的关系变为不显著,说明税收激励政策通过影响企业对创新活动的投入从而对创新绩效产生效应,即创新投入在税收激励政策与企业创新绩效的关系中起完全中介效应。(4)从税收激励政策选用的税种来看,企业所得税优惠对企业创新活动的资金投入具有显著的正向影响,而对人力投入的激励作用并不显著；以增值税和营业税为代表的流转税类优惠则对企业人力投入具有显著的解释能力,而与资金投入之间并未有显著的相关关系。从税收激励政策的优惠方式来看,与直接优惠方式相比,间接优惠方式对企业开展创新活动的资金投入与人力投入具有更为有效的激励作用,均呈现显著的正相关关系。尽管税收激励政策对企业开展创新活动的资金与人力投入具有促进作用,但具体到每一项税收激励工具,对企业创新投入的促进作用以及效果是不同的。因此,为了充分发挥税收激励政策的效用,需要根据不同优惠政策的适用范围进行合理的规划与选择,否则会降低税收激励政策的有效性。本文的创新点主要体现在以下三个方面：(1)构建税收激励政策通过创新投入对企业创新绩效产生影响的概念模型。本文在系统分析税收激励政策相关研究文献的基础上,提出税收激励政策通过影响创新投入而对企业创新绩效产生效应的概念模型。以往学者多将企业R&D投入作为影响创新绩效的重要因素,尽管众多研究证实税收优惠政策对R&D投入具有激励效应,但甚少有文献从税收激励视角切入,系统研究税收政策对企业创新绩效的影响机理。因此,本文关注税收激励政策如何通过资金投入和人力投入对创新绩效产生影响,在一定程度上丰富了有关企业创新绩效的研究成果。(2)运用问卷调查与上市公司公开数据相结合的方式检验不同类型税收优惠政策的激励效应。以往学者多采用问卷调查方式研究税收政策的相关命题。本文首先通过问卷调查数据实证验证创新投入在税收激励政策对企业创新绩效的影响过程中起到完全中介作用。在此研究结论的基础上,运用上市公司公开数据针对不同税种和优惠方式的税收激励政策进一步展开实证检验,分析各项政策对企业资金投入和人力投入的不同激励效应,使得研究结论更具可信度。(3)系统梳理我国创新税收激励政策发展历程及主要发达国家现行创新税收激励政策。本文全面收集1978～2012年政府发布有关创新的税收激励政策,并在文本信息基础上从政策年度、激励税种、激励对象、激励方式和激励环节五个方面对政策进行量化归类,按照不同时期政策的特点将其划分为四个阶段,有利于明晰我国税收激励政策的发展历程及不同阶段的特征。目前我国较缺乏此类研究。此外,由于科技活动日新月异的变化以及企业创新能力的提升,一些激励政策已与政府的政策目标不相匹配,许多国家也在修订已有的税收激励措施。以往学者对外国政策的整理多直接借鉴前人文献,在政策内容上具有较强时滞性。本文从各国政府网站中直接获取相关税收法案中有关创新的条款,对我国及主要发达国家现行有效创新税收优惠政策进行系统梳理,通过比较分析我国与发达国家税收优惠政策的特点,提出提升我国创新税收政策激励效应的有关建议,对企业结合实际情况选择适宜政策从而保障创新活动顺利开展有较好的借鉴意义。更多还原

【Abstract】 Innovation is the key link to regulate economic structure and shift the way of economic growth, and also the centre power of China social economic fast and sustainable development, especially in the critical period of a new round of great-leap-forward development. The principal part of innovation system is enterprises, and its innovation activities play important strategic position in promoting country’s innovation ability. But the statistics from related department in our country show that, although the enterprises in our country maintain rising trend in R&D input intensity, there is still a large gap comparing with the developed country, and depends on foreign technology highly, there is rarely company which has the independent intellectual property and core technology in the country. This suggests that the innovation ability of our country’s enterprises is still extremely weak. However, enterprise innovation activities will be influenced by its own economic characteristics, and the existence of market failure that makes the market mechanism failing to achieve the optimal allocation of resources, the government need to intervene and provide a good policy environment to arouse the innovation power of the enterprises. Tax incentives are adopted by governments around the world as they are more likely inclusive and to use the enterprise and market forces. This article studying the effect of tax incentives to innovation performance from the microscopic perspective of enterprise, further enrich the research on enterprise innovation, and provide reasonable reference for government policy making at the same time, and more importantly, it can help the enterprise selects appropriate incentives to serve the enterprise innovation activities in the process of business practice.According to the topic, using the literature material method, content analysis, questionnaire investigation and statistical analysis method, the article studies that how tax incentive policies affect mechanism of innovation performance from the following aspects in accordance with logic of asking questions, analyzing and solving the problems:(1) To review previous research on tax incentives and innovation performance, understand the current situation and problems of enterprise innovation activities, and clarify the development process and characteristics of the preferential tax policy in our country.(2) Based on the economic growth theory, to analysis how tax incentives affect innovation performance through innovation input, and build the appropriate conceptual model.(3) To collect data by means of questionnaire survey on tax incentives, innovation input and innovation performance, test the scale reliability, validity and confirm the theoretical model and research assumptions with the stepwise regression analysis method, then use the listed company data to do further argument.(4) To contrast the current preferential tax policy with main developed countries, and propose suggestions on promoting the incentive effects of tax policy combing with the empirical results.This paper researches the relationship between the tax incentives and enterprise innovation performance from the visual angle of innovation input. The framework of "tax incentives-innovation input-innovation performance" is established and theoretical assumptions on tax policy affecting innovation performance through capital and labor investment are put forward. The questionnaire survey data of301enterprises as well as public data of281listed companies are used to do empirical test. Analysis results show that tax incentive policy can affect the enterprise capital and labor input, and further have effect on innovation performance. Main research conclusions are as follows:(1) Tax incentives have significant positive effect on capital and labor input of corporate innovation activities. From the perspective of the correlation coefficient, the intensity on labor input is stronger than on capital investment.(2) Capital and labor input of innovation activities has significant positive effect on innovation performance, shows that adequate funding is the key element for implementation of innovation, also the human capital investment is.(3) Innovation input is a complete intermediary variable between tax incentives and innovation performance. After joining innovation input variables, the significant positive correlation between tax policy and innovation performance becomes non-significant, but innovation input still has significant positive effect on innovation performance. This shows tax incentives influencing the enterprise input of innovation activities, so as to affect innovation performance, namely the innovation input variables play full mediation.(4) From the perspective of tax categories, corporate income tax preferential treatment has significant positive effect on capital input and is non-significant with labor input. Turnover tax that represented by value added tax and business tax has significant explanatory ability to enterprise labor input but no significant correlation with capital investment. From the way of tax incentive policy, indirect preferential way has more effective incentive effect on capital and labor investment for carrying out incentive activities compared with direct preferential way. With regard to specific policies, they have different effect on promoting innovation input. Therefore, enterprises need to reasonably select these policies according to the scope of application in order to make full use of the effectiveness.The innovation point is mainly manifested in the following three aspects:(1) Build the conceptual model that tax incentives impact on the enterprise innovation performance through innovation input. Based on the systematic analysis of research literature related to tax incentives, the appropriate conceptual model that tax incentives influence the innovation input and then have effect on innovation performance is established. R&D expenditures variable is seemed as important factor which may affect innovation performance in many previous literatures. Although numerous studies have confirmed the tax policy has incentive effect on R&D expenditures, few literature study the mechanism between preferential tax policy and innovation performance from the visual angles of tax incentive. Therefore, this paper focuses on how tax incentives act on innovation performance through the intermediation of capital and labor input, and to some extent enriches the research on enterprise innovation performance.(2) Test incentive effects of different types of preferential tax policies by using questionnaire survey and public data of listed companies. Many previous literatures adopt questionnaire investigation to research tax policy. The paper firstly uses questionnaire survey data to validate the full mediation of innovation input between tax incentives and innovation performance. On the basis of that research conclusion, we develop further empirical test on different tax categories and preferential way and analyze the different incentive effect of various policies on capital and labor input, which can make the results more credibility.(3) Sort out the development of tax incentive policy in our country as well as the main developed countries. This article comprehensively collects the tax incentive policy about innovation during1978～2012, and categorizes these policies by the annual, tax type of incentives, incentive objects, motivational methods and encouraged link, then divides the development into four stages according to the characteristics of policy in different periods, which is conducive to clear the development of tax incentive policy in our country and the characteristics of different stages. And our country is relatively lack of such studies at present. In addition, as the activities of science and technology change quickly, and enterprises improve innovation ability, some incentives can’t match with the policy objective, so many countries are revising the existing tax incentives. Much more researches about organizing the foreign policies directly refer to the previous literatures, and are quite "time lag". This article obtains the terms of the innovation in tax law directly from the governments website, and sort out the development of tax incentive policy in our country as well as the main developed countries, then put forward some suggestions to improve the innovation incentive effects of the tax policy in our country, according to comparative analysis of the characteristics of the tax incentive policy between our country and developed countries, which are significant for the enterprise combining practice to choose suitable policy ensuring innovation.更多还原
