But most emission of refrigerants is man-made, unrea-sonable and needless. Since in most emission cases the refrigerants are contained in the refrigerators, we can retrieve them by some technique that changes the 'manual emission' into manual retriev-ing. To promote the retrieval action and diminish the pollution, society can use economic, administrative and technical counter-measures, which can create a 'good-cycle' both 'harnessing pollu-tion and earning income simultaneously', reinforce the motive of retrieving, and retrieve most proportion of refrigerants used by all refrigerators. This 'good-cycle' method can be easily promoted, and also a valuable way to promote other forms of environmental protection. The three countermeasures have almost no social cost, even no cost at all.展开更多

Empirical analyses show that over fifty percent of the income gap between monopoly industries and competitive industries is unreasonable and is brought about mainly by industrial monopolies. As current income statistics do not count the high welfare benefits in monopoly industries, the above results clearly underestimate the unreasonable component of the high income in these industries.展开更多
