人们常说:‘没有投入就没有产出。’笔者认为,从严格意义上说,对于投入与产出的关系,这样说还不够全面和准确。诚然,投入是产出的前提,但二者之间并不能划等号,有投入也不一定就有产出。最近,我们对本县乡镇关停企业进行了一次专题调查。据统计,共有181个企业关停,闲置厂房、设备占用农业银行信贷资金2415万元,是农行对乡镇企业信贷规模的四分之一。这些企业少者投入几万元,多者投入几十万甚至几百万元,不仅没有产出,反而成了沉重的包袱。分析原因,有的是上马时市场调查不准确,项目论证不充分, People often say: ‘There is no output without input. ’The author believes that in a strict sense, the relationship between input and output is not comprehensive and accurate. Admittedly, input is the premise of output, but there can be no equal sign between the two, and there is not necessarily output in the input. Recently, we conducted a special survey on the closure of enterprises in this county township. According to statistics, a total of 181 enterprises have been shut down. Idle plant and equipment use 24.15 million yuan of credit funds from the Agricultural Bank of China, which is one quarter of ABC’s credit to township and town enterprises. The few of these enterprises invested tens of thousands of dollars, and many invested hundreds of thousands or even several million dollars. Not only did they fail to produce output, they became a heavy burden. To analyze the reasons, some of them are inaccurate market surveys when they are launched and the project demonstration is not sufficient.
