Secondly, customers with known cycle 0 are from company A, which is within the cycle 1, 5000=3500+500+ 1000, 3000=300+2400+300, 2000 = 100+65438+.
Thirdly, we know that customers who enter A do not completely buy A's products, and the corresponding absolute market share is within the period of 1.
B.C.
35% 5% 10%
B 3% 24% 3%
1% 1% 18%
The relative customer share during the period of 1 is
B.C.
70% 10% 20%
B 10%
C 5% 5% 90%
Therefore, the nominal market share of Cycle 2A is 35%+3%+ 1%=39%, B is 5%+24%+ 1%=30%, and C is10%+3%+18% =
Therefore, it can be assumed that the changing trend during the period of 0- 1 continues during the period of 1-2, so the actual market share of product A is = 39% * 70%+30% *10%+31%* 5% = 3/kloc-0.
So we know that at the beginning of the third cycle, C became the company with the largest share, with 38.7%, A second, 365,438+0.85%, B third, 29.45%.
