单产与粮食产量始终保持很高的关联度；有效灌溉面积、实际机耕面积、化肥施用量、农村用电量和农机总动力等农业投入对粮食产量提高影响重大；耕地面积和劳动力对粮食产量具有一定的制约；自然条件与粮食产量的关联度剧烈变动。

Some views think MBO have cheating operation that lead to the state assets losses; I think MBO , as a kind of comparatively ripe system , its must not cause the loss of state assets , the objective factor influenced state assets price is much, higher or lower than net assets price may not reasonable , may not unreasonable either, the cause leading the loss of state asset is unsufficiency condition and not canonical means. We should consider interior employee especially outstanding the historical contribution factors of administrators.

笔者认为MBO作为一种较为成熟的制度，其本身并不必然导致国有资产流失，但国内影响国有资产合理定价的客观因素多而复杂，国有资产转让价格高于或低于净资产未必合理，也未必不合理；国有资产流失的原因是在条件不充分的情况下，用不规范的方法实施MBO；某些企业作低价是因为考虑了内部职工尤其是优秀管理者的历史贡献因素；当前首要目标是改制，提高社会整体经济效益，应在合理范围内以法律形式明确管理层收购价格优惠制度，促进MBO的顺利进行。
