Patent Storage Research of Cooperation between S&T-Oriented Small-Micro Enterprise and University in Triple Helix Innovation Based on EPQ Model

Abstract

Based on the government-sponsored economic production quantity(EPQ)model, this paper analyses technology patent storage problems in university-enterprise cooperation under the perspective of S&T-oriented small-micro enterprise, finds out the optimal number and cycle of patent research which can keep S&T-oriented small-micro enterprise the lowest cost of research and storage, then puts forward the future research direction.

Patent Storage Research of Cooperation between S&T-Oriented Small-Micro Enterprises and Universities in University-Industry-Government Based on EPQ Model with Shortage

“…In the current study, Su groupanalyzed patent storage issue in EPQ model in which stockouts weren't allowed [3] . They supposed that the cost of patent lacking is infinite, so that patents can't be out of stock.…”

“…In view of the demand from the novel model, we purposed some additional question assumptions based on assumption (1) (2) (4) (5) in the article of Ye and Su(2013) [3] .The assumptions are shown as follows:…”

“…The definition of symbolsP, R, Q, C 1 , C 2 , C 3 , S 1 , S 2 , Y 1 , Y 2 are the same as Ye and Su(2013) [3] . Besides, some new symbols were added and parts of the symbols were redefined as follows:…”

“…→ ∞, this model is simplified into the EOQ model established by Tang and coworkers [2] . And once → ∞, this model is transformed into the EPQ model set up by Ye and coworkers [3] .…”

“…S&T-oriented small-micro enterprises and university-industry-government are important means for China to build an innovative country.However, studies on these two objects, especially on the cooperation of the both, are scarcely reported in China. Yao and Zheng (2011) [1] utilized the three-helix theory to investigate the innovationmode of S&T-oriented small-micro enterprises in Tianjin;Su et al employed the EOQ model [2] and EPQ model [3] respectively to studythe patent storage issueon cooperation between S&T-oriented small-micro enterprisesand universities. In the background ofuniversity-industry-government,current researches seem to be unable to meet the demand from the development of S&T-oriented small-micro enterprises.…”
