摘要
国际上常用的世界经济增长率测算方法有按汇率法或按购买力平价(PPPs)法加权的连锁加权法和固定基期法。用不同方法测算出不同的数据结果,它们各有优缺点和独特的经济涵义,满足不同的经济研究目的需要。统计数据分析表明,按PPPs法加权的世界经济增长率要明显高于汇率法加权的结果。但不论按何种方法测算,自1980年以来,中国对全球经济发展的贡献不断增大,现已成为拉动世界经济增长的重要引擎。
There are different estimated methods of world GDP growth rate in the international community: chained-weight Paasche-type and fixed base Laspeyres-type formulations, weighted by GDP at the current/constant exchange rates or PPPs separately. No single method is mathematically superior to the others since each method has its relative strengths and weaknesses. The results differ strongly depending on whether PPPs or exchange rates are used as weights. Since 1980s, China′s contribution to the global economic growth has been increaseing coutinually and now China has become an important engine for driving world economic growth.
