Cov txheej txheem kev tshuaj xyuas ntau lawm

Cov txheej txheem kev txheeb xyuas cov txheej txheem tsim khoom yog txhawm rau txheeb xyuas tag nrho cov txheej txheem tsim khoom thiab kev ua haujlwm ntawm lub tuam txhab, txheeb xyuas qhov txaus ntshai ntawm txhua qhov txuas los ntawm cov khoom, thiab tshawb pom ntau yam muaj feem cuam tshuam. Txoj kev tsom xam cov txheej txheem yog txhawm rau txheeb xyuas qhov txaus ntshai los ntawm kev txheeb xyuas cov txheej txheem tsim khoom / kev pabcuam kev ua haujlwm lossis kev tswj hwm kev lag luam. Yog hais tias cov tswv yim-tsim kev tsom xam technology ntawm input technology economics ua ke, nws yuav yog ib qho kev pheej hmoo ntawm kev txheeb xyuas thiab kev ntsuam xyuas technology.
