2026备考丨习题打卡25期(农业经济)
哈喽，大家好！
我是匠匠~
2025年高级经济师评审落下帷幕，标志着新一轮备考周期正式到来，2026年高经备考热潮随之升温，目前有不少同学已经加入备考队伍中来！
今天领匠26年习题打卡-正式开启，记得搬好小板凳来学习哟~

习题打卡25期（农业）

20世纪80年代，我国的工资水平还处在以两位数计算的时代，月收入超过100元的仅占少部分，1985年城镇居民人均可支配收入为739元，农村居民人均可支配收入为398元。相对于人们的收入水平，我国家电产品的价格普遍较高，当时最普通的一款冰箱卖到2 800元左右，而且需要凭票供应，因此出现了1989年凭票排队抢购冰箱的场面。
2023年，我国城镇居民人均可支配收入已经达到51 821元，农村居民人均可支配收入已经达到21 691元，而冰箱的价格却不升反降，某品牌一款中端三开门冰箱的售价低于2 500元。家电市场百花齐放，各种品牌应有尽有。
问题：
1.为什么随着人均收入的增长，电冰箱的价格会下降？请根据供求理论进行阐述。
2.请简述影响农产品供给弹性的因素有哪些。
