THE IMPACT OF WORLD HEALTH ORGANIZATION’S OFFICIAL ANNOUNCEMENTS ON PHARMACEUTICAL COMPANIES STOCK RETURNS

ABSTRACT

AGAINST THE BACKDROP OF ESCALATING GLOBAL CLIMATE CHANGE AND CHINA BEING THE WORLD’S LARGEST CARBON EMITTER, THIS STUDY EXPLORES THE IMPACT OF THE CARBON TRADING SYSTEM ON GREEN FINANCE IN CHINESE POWER SECTOR. THIS STUDY USES A QUANTITATIVE RESEARCH METHOD, NAMELY A DIFFERENCE-IN-DIFFERENCES (DID) MODEL, TO INVESTIGATE POWER COMPANIES THAT PARTICIPATED OR HAD THE POTENTIAL TO PARTICIPATE IN CARBON TRADING IN 2019 AND 2022. THE KEY FINDING IS THAT COMPANIES THAT PARTICIPATED IN CARBON TRADING HAD SIGNIFICANTLY HIGHER GREEN FINANCE THAN THOSE THAT DID NOT PARTICIPATE, INDICATING THAT THE CARBON TRADING SYSTEM HAS A POSITIVE IMPACT ON PROMOTING GREEN FINANCE. HOWEVER, THE IMPACT DOES NOT SIGNIFICANTLY INTENSIFY AFTER THE NATIONAL CARBON TRADING SCHEME WAS IMPLEMENTED IN MID-2021. THE GREEN FINANCE OF LISTED COMPANIES AND STATE-OWNED ENTERPRISES WERE LESS AFFECTED BY CARBON TRADING, POSSIBLY BECAUSE THESE COMPANIES RELY ON ALTERNATIVE FINANCING OPTIONS AND GOVERNMENT FINANCIAL SUPPORT. DUE TO THE FINDINGS, THIS STUDY RECOMMENDS THAT POLICY MAKERS SHOULD STRENGTHEN THE PROMOTION OF THE CARBON TRADING SCHEME AND PROVIDE MORE SUPPORT FOR NON-LISTED COMPANIES AND NON-STATE-OWNED ENTERPRISES. AT THE SAME TIME, THE COMPANIES SHOULD ACTIVELY PARTICIPATE IN THE CARBON MARKET TO TAKE ADVANTAGE OF THE INDUSTRIAL POLICIES TO ENHANCE GREEN FINANCE, AND ULTIMATELY PROMOTE ENVIRONMENTAL PROTECTION AND THEIR OWN SUSTAINABLE DEVELOPMENT
