First, we discuss a monopolistic downstream firm's decision of outsourcing in the final good market. Then we extend the model to a duopolistic downstream market structure with two competing firms to examine whether the outsourcing decisions change in such a competitive environment.

模型推导以渐进式进行，首先讨论当最终财市场结构为独占下，最终财厂商的委外决策；其次开放市场竞争程度，使最终财市场结构由独占转为寡占，厂商家数由一扩增为二，且两厂商在最终财市场进行同质产品的数量竞争，则最终财厂商的委外决策是否改变。

In this case, there exist two effects: one is that, due to the market competition, the duopolistic downstream firms' market shares and their revenues decrease, thereby lowering their ability to burden the fixed costs of setting up a manufacturing factory; the other is that the increasing demand for the intermediary goods from the downstream firms raises the upstream firm's incentive to accept the outsourcing contract.

一方面最终财厂商因市场竞争，所得到的市场份额会相对缩小，收益自然减少，造成负担固定成本支出的能力下降，进而提高委外生产的意愿。

Signal peptide sequence was removed lest it couldnt be recognized by Bacillus subtilis, gene coding for mature peptide was ligated to downstream of sacB signal peptide sequence of pWB980 to form a new ORF and generate pWB980-LipA, gene coding for its chaperone was also amplified and ligated to the downstream of LipA to generate a secretion/expression vector pWB980-LipAB.thechaperone gene was sequenced and analyzed by multiple alignments, resulted showed that there were mutations of nucleotides(1～7) and amino acids (1～2) with the other reported genes.
