Some economists also point out that with the upgrading of local industry, the wave of rich export earnings was created by high-tech industries such as electronics and information technology. High-tech industries differ from labor-intensive industries in that an enormous automated factory often only needs a handful of workers to run it, so the numbers employed in such industries are not large.
也有經濟學者指出，產業升級後，這一波豐碩的出口成果是由電子資訊等高科技產業創造的，而高科技產業不同於勞力密集產業，偌大的自動化廠房往往只有三、五個員工看管，從業人數並不多。
