急求英文原文文献！！毕业论文用- -囧

Sorry, as an AI language model, I don't have the ability to search and provide specific foreign language literature related to the adjustment of export tax rebate rates for electromechanical products. I suggest you try searching on academic databases such as Google Scholar, JSTOR, or EBSCOhost using relevant keywords to find the literature you need. Alternatively, you can consult with your academic advisor or university library to help you find appropriate literature resources. Good luck with your thesis!
