有鑑於此，研究團隊與全國公信力民意調查股份有限公司合作，合併2007年迄今（2013年3月）該公司所執行抽樣範圍為全國的原住民電話訪問成功樣本成為原住民電話資料庫，以為調查之用。初步研究結果顯示，使用雙重抽樣方法所整併的電訪樣本資料庫進行電話調查，所獲得之成功樣本特徵與官方人口統計中的原住民母體特徵近似。同時，納入跨年度的原住民電話資料，能夠更有效地提升前述原住民電話資料庫的蒐集範圍，並降低樣本取得成本。
There is a lack of indigenous object research inside the nation, and the research is usually attached to national sample as one of the small sample analysis. The main reason is that with only about 2% of the country's total population, indigenous population is rather few in Taiwan. Besides, uneven geographic distribution and the factor that a considerable number of workplace/residence and domicile difference due to livelihood are other reasons which cause difficulty to traditional method of investigation. Both face-to-face interview or telephone interview have handicap on sampling. However, public opinion polls had become more universal in recent years. Academic and private investigation agency all has accumulated a large number of successful phone survey samples, which contained numerous Han samples and certain proportion of indigenous samples. If there is a possibility to get these samples which were ＂not originally using indigenous population as statistic population, but contain successful indigenous samples,＂ and apply data mining technology to dig the ＂valuable mineral＂ out from a large amount of ＂useless＂ information, then it will be probable to directly filter out the indigenous samples that were needed, and solve the problems mentioned above in the context of saving cost. In this view, the research team and Taiwan Real Survey Co. had cooperated and merged the successful indigenous population phone interview samples, which are from national samplings that were executed by the company since 2007 so far (March 2013), as indigenous telephone database. Preliminary research result shows, by using telephone interview sample database that was consolidated by data mining and double sampling, the characteristics of successful samples which got from the telephone interview are similar to the indigenous statistic population in the official population statistics. Other than that, including multi-year indigenous population phone data could enhance the collection range of the indigenous telephone database, and reduces the cost of sample acquisition.
