第四章 生产函数（The fourth chapter is production function） You must know something, or die better. - Roman Roland The fourth chapter is production function I. judgment questions 1., the premise of diminishing marginal production and the principle of scale income are both technical level. () 2., when other factors of production remain unchanged, the more input of a factor of production, the higher the output. () 3. on the same plane there can be three equal yield lines. () 4., the law of diminishing marginal production and the principle of scale returns are the same question, and the conclusions are the same. () 5., in agricultural production, the more densely planted land, the better the more fertilizer. () 6., the marginal production curve intersects the average yield curve at the highest point of the average yield curve. () 7. when a certain quantity of products is produced, the ratio of the factors that can be invested can be changed and fixed. () 8. the upper part of an equal yield line indicates output greater than the lower part of the yield line. () Two, multiple-choice questions 1. in economics, the term short-term refers to (). A. a period of one year or less B. during this period all inputs are variable C. during this period all inputs are immutable D. during this period, at least one input is fixed, and at least one input is variable The amount of change in total output caused by an increase of 2. variable inputs is called (). A. average yield B. marginal production C. average variable yield D. total output 3. when hiring seventh workers, the weekly output increased from 100 units to 110 units; when hiring eighth workers, the weekly output increased from 110 units to 118 units. A. diminishing returns to scale B. marginal cost decreasing C. diminishing marginal returns D. labor intensive production 4., the problem of diminishing marginal production is studied A. effects of simultaneous changes in production factors on output. B. effects of simultaneous changes of
