论经济增长速度和经济效益

经济增长速度和经济效益是两个不同但又相互密切联系的概念。经济增长是长、短两个不同时期的新增产值的对比,而经济效益则涉及不同时期的利润与总成本的对比。在长期中,经济效益是经济保持一定增长速度的基础,因为经济的长期增长取决于利润持续转化为投资,而只有不断改善经济结构、提高技术水平和产品档次,才能有高利润率（高效益）,才能有持续的新增投资,并取得理想的增长速度。但是在短期内,没有速度就一定没有效益,因为成本刚性在短期里难以克服。在剩余劳动力较多的国家,保持一定的经济增长速度也是取得社会效益的前提。中国的国情决定了中国必须在提高技术水平和广泛利用劳动力之间达到有效的协调。

On the Economic Growth Rate and Economic Efficiency

Economic growth rate " and " economic efficiency" are different and closely related concepts. The economic growth is the comparison of added value between two periods, while the economic efficiencey is dealing with the comparison of profits and total costs between two periods. In long run, the economic efficicncy is the base of economic growth, for that the continue economic growth depends on the investment coming from profit mainly, while only the improvement of economic structure and raising of technology level can supply higher profit rate and sufficient investment. But in short run, lower growth rate surely means lower efficiencey, for that the rigid cost problem can not be overcome in the short run . To keep a higher economic growth rate also is the precondition for countries with surplus labor to get the target of social stable. The characteristic of China has decided that, China must coordinate better the relations between the technology improvement and the broadly taling use of labor.
