This study investigates the effect of international coproduction on the performance of cultural products in the global markets. As a result of institutional barriers and cultural distances, coproduction, which allows a foreign producer to partner with the local firms, has emerged as a way of increasing cultural product performance in the global markets. Using the data on the Chinese movie market from 2012 to 2018, the authors find that international coproduction can promote movie performance and that the coproduction effect is mainly explained by the institutional variables. They further examine the heterogeneous effects and find that coproduction effect is stronger for culturally sensitive movies, and that the magnitude of the coproduction effect increases with the level of cooperation. They also confirm that the results are robust to different measurements of performance.
为了提高双离合变速器在车辆上的换挡品质,提升电气化换挡执行机构的工作效率,给出执行机构性能与换挡品质评价准则;通过两种不同双离合变速器电控电动执行机构的工作原理与性能分析,基于MATLAB数值仿真方法优化出最高效率进行试验.基于车辆6个维度的换挡工况对二者所搭载的变速器分别进行试验与CAN线数据采集,对比研究两种机构优缺点,通过雷达图的方式进行优劣说明.结果表明,两种执行机构传动效率可达70%且换挡品质相当.可见Tip in tip out工况对二者要求最为严格. 相似文献
