本文通过建立基于内生增长理论的模型，说明技术研发外包活动可以增加新的中间投入产品，进而促进了企业产品创新。然后利用多层混合效应logistic模型检验企业外包行为对企业引入新产品的影响，结果表明：企业研发外包会显著提高该企业引入新产品的概率，企业研发外包可使得该企业引入新产品的概率提高5．6倍；来自市场竞争的压力也会激励企业积极提高自己的竞争能力，使得企业引入新产品的概率提高了40％-50％；但随着市场竞争程度的加剧，降低了企业研发外包能够提高该企业引入新产品的促进效应。
本文通過建立基于內生增長理論的模型，說明技術研髮外包活動可以增加新的中間投入產品，進而促進瞭企業產品創新。然後利用多層混閤效應logistic模型檢驗企業外包行為對企業引入新產品的影響，結果錶明：企業研髮外包會顯著提高該企業引入新產品的概率，企業研髮外包可使得該企業引入新產品的概率提高5．6倍；來自市場競爭的壓力也會激勵企業積極提高自己的競爭能力，使得企業引入新產品的概率提高瞭40％-50％；但隨著市場競爭程度的加劇，降低瞭企業研髮外包能夠提高該企業引入新產品的促進效應。

The paper constructs a model based on the endogenous growth the- ory to clarify the mechanism through which enterprises＇ R＆D outsourcing activi- ties expand the varieties of new intermediate inputs, and thus promote the enter- prises＇ new products creation. By employing the multilevel mixed- effects logis- tic regression method, the paper conducts an empirical analysis to test the effect of enterprises＇ R＆D outsourcing on its new products development. The results suggest that enterprises＇ R＆D outsourcing has a significant positive effect on its new products development, which increases the probability of new products intro- duction by 5.6 times. The pressure from market competition will also encourage enterprises to improve their competitive ability actively, which improves the proba- bility of new products development by 40 to 50 percent. However, the promoting effect of enterprises＇ R＆D outsourcing on its new product introduction will wane when the market competition continues to intensify.
