普惠金融的税法规制

普惠金融是一种旨在为社会弱势群体谋求公平的金融发展权利的新兴理念,其与我国当前的精准扶贫政策高度契合,故此推动普惠金融发展在当下具有重要意义。普惠金融的税法激励被屡屡提及,但是缺乏全面系统的理论阐述、制度设定和规范建构。实际上,普惠金融的税法规制是一种带有特定公共利益倾向的政策性规制,其具有理论正当性;同时税法规制的激励性功能和补偿性功能构成其合理性依据。当前我国普惠金融的税收优惠依赖于政策性文件,缺乏系统性考量,其内容设计较为粗糙,税收优惠的公平性和保障性尤为不足,其实际效果也有待观察。对此,采用转向制度化的规范之治、差异化的激励机制、实质性的监管约束等法治化路径应该是将来理想的规制方案。

The Double Excitation： A Solution to Improve Energetic Performances of High Power Synchronous Machines

DFSM （doubly fed synchronous machine） presents several advantages such as efficiency improvement, weight reduction and increase of the utilization factor （kW/kg）. In this paper the authors focus on impact of the DFSM on the efficiency and machine weight in comparison to conventional synchronous generator with wound rotor. Different topologies of DFSM are briefly described and the different methods and models for performances prediction are presented.
