问题 单项选择题

根据产业间产出的关联效应来选择主导产业,由于()具有较高的前、后向关联效应。因此在资源分配上常给予优先地位。

A.农林牧渔

B.纺织工业

C.重化工业

D.食品工业

答案

参考答案:C

解析:在实践中,运用产业关联标准选择主导产业主要通过影响力系数和感应度系数来衡量产业关联强度。一个产业影响其他产业的程度叫影响力,受其他产业影响的程度叫感应度,分别把这两种程度系数化就得到影响力系数和感应力系数。产业关联度是影响力系数和感应力系数之和。重化工业的高产业关联特征主要表现为内部产品自我循环量较大,不仅是中间产品的最大供给者,也是中间产品的最大需求者,具有较强的前向和后向产业波及效果。

Dear John,

     Thank you very much for your letter. I am glad that you enjoyed your holiday with me. We enjoyed having

you and your sister here. We hope that you will both be able to come again next year. Perhaps you'll be able

to stay longer next time. A week is not really long enough, is it? If your school has five weeks' holiday next

year, perhaps you will be able to stay with us for two or three weeks.

     We have been back at school three weeks now. It feels like three months! I expect that you are both

working very hard now because you are in Grade Two now. Tom and Ann won't be in Grade Two until

2007. They went for a picnic yesterday but I didn't go with them, because I hurt my foot and I couldn't walk

very well. They went to an island and enjoyed themselves there.

     Tom, Ann and I send our best wishes to you. We hope to see you soon.

                                                                                                                                                  Yours,

                                                                                                                                                  Michael
