Taking mountainous and island counties in Zhejiang Province as research samples

this paper focuses on the dynamic equilibrium of responsibility

authority and benefit in technology achievement transfer payment. By constructing a multi-dimensional evaluation model and conducting case studies

it reveals the mechanism logic of scientific and technological resource redistribution in underdeveloped areas. Based on micro-data from 26 mountainous counties and Zhoushan's island counties in Zhejiang Province from 2021 to 2023

using the balance of responsibility-authority-benefit balance degree model、evolutionary game model、DEA efficiency analysis

combined with matching cases from the "Supply-Demand Hub" platform and central government-guided fund usage data. It is found that mountainous island counties have achieved initial allocation of scientific and technological resources through mechanisms such as "trial use first

payment later" and "demand-oriented transfer"

but core contradictions exist including insufficient empowerment of authority (coverage rate only 49%) and unbalanced benefit distribution (enterprises' profit-sharing ratio 30%). The study proposes an optimization path of "dynamic empowerment + phased profit-sharing + digital collaboration"

providing a practical paradigm for regional coordinated development.
