【论文速递】新能源汽车产业政府补助与市场融资的创新激励效应

摘要：本文选取2015-2018年新能源汽车产业110家上市公司面板数据，探索政府补助与市场融资及其协同配合对企业研发创新影响的差异性。结果显示，新能源汽车产业政府补助对企业研发创新具有显著激励效应，市场融资并未显著促进企业研发创新，政府补助与市场融资协同配合能有效促进新能源汽车产业研发创新。通过进一步研究发现，处于不同新能源汽车产业链阶段的企业，政府补助对中上游企业研发创新的激励效应更大，而市场融资对下游企业研发创新的激励效应更大，政府补助与市场融资协同配合对中上游企业研发创新的激励效应更大。同时，相对于国有企业，新能源汽车产业政府补助与市场融资及其两者协同配合对非国有企业研发创新的激励效应更大。本文在一定程度上丰富了创新激励与政府干预理论，并为政府扶持新能源汽车产业精准设计创新政策提供理论指导。

Abstract: To cultivate and develop the new energy vehicle industry is an effective solution to reduce the pressure on fossil energy and environment. But its technological bottleneck is a main problem in the industrial development. To promote R&D and Innovation is an important way to obtain industrial technological progress by governmental subsidies to compensate firm R&D and innovation input for high uncertainty and spillover effects. Currently, there are three main theoretic problems to be discussed, i.e., how do governmental subsidies and market financing stimulate firm innovation in China new energy vehicle industry? Whether governmental subsidies encourage firms to increase innovation input with their own financing funds？In the context of the reduction in government subsidies，how to balance the monetary policy and fiscal policy for the new energy vehicle industry in the future?

Existing studies mainly focus on the vertical comparison to stimulate innovation between government subsidies and market financing. Some literatures focused on the impact of government subsidies on firm innovation，emphasizing its stimulative effect and crowding out effect on firm innovation. Others focused on the relationship between financing constraints and firm innovation to analyze their promoting effect and exclusion effect of firm innovation in terms of firm financial growing. However, very few studies have integrated governmental subsidy and market financing into the same research framework to explore the different impacts of the two aspects on innovation input of new energy vehicle industry and their coordinative effects between the two variables on firm innovation. Therefore, it is difficult to answer whether the government subsidy policy can stimulate firms to increase private innovation input, and how the government should design fiscal policy and monetary policy for the new energy vehicle industry so far.

In this study, we collected the data in the annual reports of 110 new energy vehicle firms listed during 2015 to 2018 in China stock market from the CSMAR database and the WIND database, to classify the data of fiscal subsidies and tax incentives, equity and credit financing by careful reading their annual reports. In terms of the panel data, we have done comparative studies between governmental subsidies incentives, such as fiscal subsidies and tax incentives to the firm innovation, between equity financing and credit financing to firm innovation effects. And，this paper explores the collaborative effect on firm innovation by the interaction between government subsidies and market financing, comparative studies by upper, middle and downstream firms in terms of industrial chains, and state owned and non-state-owned firms in terms of firm ownership.

The empirical study shows that government subsidies and market financing have different incentive effects on firm innovation. Specifically, both fiscal subsidies and tax incentives can significantly stimulate firms to increase R&D investment, and the role of fiscal subsidies is greater than that of tax incentives, while credit financing and equity financing do not promote firm R&D investment significantly. On the one hand, firms do not use their market financing funds into the R&D activity. On the other hand, the study also shows that government fiscal subsidies do not drive firms to input private R&D, instead of, making more dependence on government.

Moreover, the coordination between government subsidies and market financing can effectively promote firm innovation of new energy vehicle industry. The study indicates that when firms have more market financing, they are more willing to use government funds for innovation. On the contrary, when it is difficult for firms to obtain external market financing, they will use government subsidies for other purposes.

Furthermore, this study finds that firms in the industrial upstream are more dependent on government subsidies and seldom use the funds obtained from the market financing for R&D purpose, and there is no driving effect of governmental policy. The middle and downstream firms can use the government subsidies funds for R&D purpose, and input market financing for R&D use either. In this case, governmental policy can generate driving effect in good results. Therefore, in the downstream of the industry, combination between government subsidy and market financing can generate greater incentive effects on firm innovation than that of middle and upstream firms.

Finally, the empirical study also reveals that there are differences of governmental policy incentive effects to innovation between state owned firms and non-state-owned firms. The policy has greater positive impacts on non-state-owned firm than that of state-owned firm significantly. In other words, it means that non-state-owned firms are more likely to use market raising money into R&D and innovation，and government subsidy policies plays more significant positive effect to promote equity and credit financing of non-state-owned firms than that of state counterpart, because these firms got from government subsidy can transmit positive information to the market.

The conclusions of this paper have the following policy implications: (1) In the context of reduced government subsidies year by year, the government should gradually shift from fiscal subsidy policy to monetary policy based on market mechanism. For instance, policies such as interest rate subsidy and loan guaranty are more effective tools to reduce firm financing cost, so as to encourage firm innovation input. (2) government policies for the new energy vehicle industry need to be reformed and more focused in terms of different industrial chain stages and in different ownership precisely. For these firms in the middle, upstream of the industry and non-state-owned firms, government should focus policy on fiscal subsidies and loan supporting, helping them overcome financing constraints. For these firms in downstream of the industry, government should cut down fiscal subsidies, and increase loan support, to encourage firms to carry out innovation in market orientation. (3) Governmental policy should be more precise and flexible depending on the industrial chain and firm ownership, combination of fiscal subsidy and monetary policies based on market orientation would be more effective to firm innovation, and the subsidies should be more focusing on non-state-owned firms because they are more efficiency to use their subsidy.
