【答案解析】The most significant affairs influencing the reform of Chinese economic system in the past few years and the next few years is no more than the accession to WTO. Especially in the past two years, almost every reform is trying to meet the needs of WTO, while the pace of reform is obviously accelerated and the depth of reform is getting more and more closely to the most crucial field of planned economy.
