从今年６月底以来，由于我国南方部分省份发生洪涝灾害，造成当地猪肉短缺，我省部分城市的生猪开始“支援”南方市场，再加上近几年生猪价格过低，饲养成本上升，部分地区发生疫情等因素的影响，我省生猪生产下降。2007年4月以来，生猪及猪肉供应偏紧，价格出现较大幅度上涨。目前，我省部分城市的生猪、猪肉价格逐渐达到今年新高点，个别市的肉价甚至达到了历史最高点。猪肉价格一涨，苦了居民，喜了农民。农民有了按劳等值的收获，当然高兴。但城市居民的生活受到影响，富了的城市人毕竟是少数，大多数城市居民还是低收入者，面对十几元一斤的猪肉实在尴尬。

结合上述材料，回答下列问题：

小题1:（1）谈谈你对当前猪肉价格上涨原因的认识。（6分）

小题2:（2）简析猪肉价格上涨对企业生产和居民生活可能会产生哪些影响？（7分）
