什麽是亞馬遜産品生命周期理論？

产品生命周期理论

产品生命周期（Product Life Cycle）观念，简称PLC，是把一个产品的销售历史比作象人的生命周期一样，要经历出生、成长、成熟、老化、死亡等阶段。就产品而言，也就是要经历一个开发、引进、成长、成熟、衰退的阶段。

（1）産品開發期

從開發産品的設想到産品制造成功的時期。此期間該産品銷售額爲零，公司投資不斷增加。

（2）引進期

新産品新上市，銷售緩慢。由于引進産品的費用太高，初期通常利潤偏低或爲負數，但此時沒有或只有極少的競爭者。

（3）成長期

産品經過一段時間已有相當知名度，銷售快速增長，利潤也顯著增加。但由于市場及利潤成長較快，容易吸引更多的競爭者。

（4）成熟期

此時市場成長趨勢減緩或飽和，産品已被大多數潛在購買者所接受，利潤在達到頂點後逐漸走下坡路。此時市場競爭激烈，公司爲保持産品地位需投入大量的營銷費用。

（5）衰退期

这期间产品销售量显著衰退，利润也大幅度滑落。优胜劣汰，市场竞争者也越来越少。不同阶段的销售策略

"Well, it seems that some Chinese pirates determined to capture this boat, murder all the foreigners on board, rob the Chinese passengers, and then get away on a junk that was to be ready to receive them. They made their plans, and on a certain day fifty of them took passage from Canton to Hong-kong. When about half way, they were to meet a junk with more men; and as the junk hung out her signal and came near, the fellows were to fall upon us with their knives, and capture the boat. They intended to kill us all, but their scheme failed, as there were four ships at anchor that day close by the spot where the junk was to meet them, and so the junk took the alarm and left. There was no disturbance, and we did not have a suspicion of anything wrong. Finding they had failed with us, they went the next day and captured the steamer Spark, which runs between Canton and Macao. They killed the captain and officers and the only European passenger who happened to be on board,[Pg 404] plundered all the native passengers, and got away. Some of them were afterwards captured, and confessed to their part in the affair, and then the whole story came out that they had intended to rob this boat. Since then we always have the gratings down, so that the third-class passengers cannot come on deck; and we keep plenty of rifles and revolvers in the pilot-house and captain's cabin ready for use. They may never try it on us again, and we don't intend to give them a chance to do so." "Smith, if you interrupt me again, sir, you'll find the road back to your regiment. Opposite that blacksmith's shop you'll see a white cottage. There's a young lady stopping there to-night, a stranger, a traveller. The old lady who lives there has taken her in at my request. See that the young lady gets this envelope. It's no great matter, merely a pass through our lines; but it's your ostensible business till you get there; understand?" He appeared to be addressing the air generally. [Pg 133] In a dreary kind of way she found herself answering questions. Somebody had placed a book in her hands and had told her to kiss it. These conditions of short range and great force are best attained by what may be termed percussion, and by machines which act by blows instead of positive and gradual pressure; hence we find that hand and power hammers are the most common tools among those of the smith-shop. I should have to engage a moving-van to return your gifts. magnificent, man's sort of room. I sat down on the edge of a big It has been shown how universal space and universal thought at once contain and explain each particular space and each particular concept. In like manner, the infinite substance contains and explains space and thought themselves. Contains them, yes, as attributes; but explains them, how? As two among an infinity of attributes. In other words, if we ask why there should be such an existence as space, the answer is because existence, being infinite, must necessarily include every conceivable thing. The argument is strikingly like a principle of the Epicurean philosophy, and may well have been suggested by it. According to Lucretius, the appearance of design in our world need not be attributed to creative intelligence, because infinite atoms moving in infinite manners through infinite time, must at length arrive, after a comprehensive series of experiments, at the present frame of things;562 and the same principle is invoked on a smaller scale to account for the origin of organised beings, of memory, and of civil society.563 In both systems, infinite space is the root-conception; but what Lucretius had legitimately used to explain becoming, Spinoza illegitimately applies to the elucidation of being. At one stroke all empirical knowledge is placed on an à priori foundation. By assuming unlimited credit at the bank of the universe we entitle ourselves to draw a cheque for any particular amount. Thus the idea of infinite attributes is no mere collateral speculation, but forms an407 essential element of Spinozism. The known varieties of existence are, so to speak, surrounded, supported, and fixed in their places by the endless multitude of the unknown. And this conception of being as absolutely infinite, is another proof of Spinoza’s Platonic tendencies, for it involves the realisation of an abstract idea, that is to say, of Being, which the philosopher treats as something more comprehensive than the facts of consciousness whence it is derived. VII. “This place is empty, too,” Dick agreed. “Where could?——” "You're the feller they call Shorty, of Co. Q?" And there wasn't going to be a chance, Albin decided. He exchanged a word or two absently with Derban and they went to the door together. Albin reached for the door but Derban's big brown hand was already on it. He grinned and swung the door open. There was a big outcry in Peasmarsh against Backfield's treatment of the Realfs. Not a farmer in the district would have kept on a hand who had burnt nearly the whole farm to ashes through bad stacking, but this fact did little to modify the general criticism. A dozen excuses were found for Realf's "accident," as it came to be called—"and old Ben cud have afforded to lose a stack or two, surelye." HoME 免费的日韩一级视频在线观看ENTER NUMBET 0015kmxb.com.cn
