提供价格激励 literally means provide a boost in the price. The Chinese was translated from English and personally I found the translation a bit awkward. The source text is: "The program is the most effective way to address global warming as it creates a financial incentive for reducing pollution and a profit motive for developing clean technologies." So the sentence in the source is: "it creates a financial incentive for reducing pollution" Reference: http://www.mercurynews.com/2017/07/16/cap-and-trade-advocate-business-supports-anti-pollution-pro-clean-tech-bill/ 希望對你有幫助。
