从八十年代中期开始,我国就在各省的部分城市和农村开始了城市居民、物价和农村住户的抽样调查工作,九十年代后期,我国又在各省级中心城市开展了规模以下企业抽样调查。实践表明,由国家直接开展的这些抽样调查工作,对快速、准确获取统计数据发挥了重要作用,但也存在不少问题。 Since the mid-1980s, our country began to carry out sample surveys on urban dwellers, prices and rural households in some cities and rural areas of various provinces. In the late 1990s, our country also conducted sample surveys of enterprises below designated size in various provincial-level central cities . Practice shows that these sample surveys carried out directly by the state play an important role in obtaining statistics quickly and accurately, but there are still many problems.
