从人口经济协调角度，探讨了国内生产总值、人口经济弹性系数、粮食产量等经济指标所决定的人口最大承载量和最适宜人口。研究认为河南省2000年温饱型标准的适度人口为1．0亿，小康型为0．8亿，富裕型为0．46亿；2010年温饱型为1．27亿，小康型为1．01亿，富裕型为0．92亿；2030年富裕型适度人口为1．23亿。 From the perspective of population economy coordination, the maximum population carrying population and the most suitable population determined by economic indicators such as GDP, population economy elasticity and grain output are explored. The study suggests that the moderate population of Henan Province in 2000 was 1.0 billion, that of a well-to-do 80 million, and that of a well-off 0.46 billion. In 2010, the subsistence level was 127 million while the well-to-do ratio was 1.01 Billion, the wealthy type is 0.92 billion; the wealthy moderate population in 2030 is 123 million.
