本文以中国36个工业行业的面板数据为样本,基于市场结构、行业技术机会、政府资助规模三个维度,运用门限回归模型分析法,检验政府直接资助、金融机构贷款、税收优惠所具有的R&D投资激励效应。本文研究结果表明,政府接资助、金融机构贷款、税收优惠的不同政策在R&D投资激励效应上具有差异性。其中,政府直接资助对企业R&D投资具有显著的挤入效应,金融机构贷款的激励效果不够明朗,税收优惠激励效果已开始出现成效。同时,R&D投资的政策激励效应还受到行业异质性的影响。根据上述研究结论,本文提出了相应的政策性建议。
Based on the panel data of 36 industries in China, this paper uses Threshold Regression Model Analysis method based on the three dimensions of market structure, industry technology opportunities and government-funded scale to test the R & D of R & D of government subsidies, loans of financial institutions and tax incentives Investment incentive effect. The results of this study show that the different policies of government subsidy, loan of financial institutions and tax incentives have differences in the incentive effect of R & D investment. Among them, direct government subsidy has a significant crowding-in effect on corporate R & D investment, the incentive effect of loans to financial institutions is not clear enough, and the tax incentives have begun to take effect. At the same time, the policy incentives for R & D investment are also affected by the heterogeneity of the industry. According to the above conclusions, this paper put forward the corresponding policy recommendations.
