Now the term threshold effect was given so because in the field of business a phenomenon is observed in which the sales of that particular company surpasses a specific and fixed quantitative limit which is known as the threshold, hence this effect too was given the name ‘Threshold effect’. For the level of economic development, it is a core explanatory variable and has a significant impact on environmental governance only when the efficiency of science and technological services is below the threshold value. What sets one group apart from the other? 174 Shazhengjie, Shapingba, Chongqing, China. Some changes are gradual and benign, but others, especially those associated with catastrophic mass extinction, are relatively abrupt and destructive.
