摘要:基于20家新能源汽车互补产业上市公司2015-2021年财务数据，并对其采用门槛效应模型就政府补助与新能源汽车互补产业之间的关系进行实证研究.研究结果表明:政府补助与新能源汽车互补产业的发展之间显著的双重门槛效应,只有在政府补助力度处于(0.061,0.063)区间时,政府补助才能对行业发展起到显著的正向作用。因此,我国政府应当严格规划,确保补助力度处于最优区间,同时对于补助落实过程严加管理,确保补助能够推动相关产业的发展。
Abstract: Based on the research on the financial data of 20 listed companies in the complementary industries of new energy vehiclesfrom 2015 to 2021, and using the threshold effect model, the relationship between govermment subsidlies and complementary industries ofnew enery vehicles is empirically studlied. The resuls show that there is a significant double threshold effect between government subsidiesand the development of complementary industries of new energy vehicles, and only when the govemment subsidies are in the (0.061,0.063)range， govermment subsidlies can play a significant positive role in the development of the industry. Therefore, the Chinese govermmentshould stictly plan govermment subsidies to ensure that the intensity of subsidies is in the optimal range, and at the same time strictlymanage the implementation process of subsidies to ensure that subsidies can promote the development of related industries.
