生态工业园建设中普遍面临企业参与积极性不高、生态链网建设投资不足问题,为此,根据园区企业间生态协作契约的不完全性特征,在把生态工业园生态链网建设分为预处理资产投资过程和商品化资产投资过程的基础上,运用不完全契约理论分析了园区生态链网建设投资不足问题的成因,进而从政策干预和产权安排两个方面分析了刺激园区生态链网建设的激励机制,并提出了相关政策建议。研究认为:(1)废弃物再利用过程中的资产专用性、生产不确定性、互信性以及企业地位等因素引致了园区生态链网建设投资不足问题;(2)价值类补贴干预只具有参与激励作用而缺乏投资激励作用,园区应更注重投资类补贴措施的应用;(3)当具有废弃物环境影响大、商品化资产对预处理资产强依赖、排放企业地位至关重要等特征时应鼓励排放企业的纵向一体化,反之,当园区具有处于初期发展阶段、商品化价值高、预处理资产对商品化资产强依赖、利用企业地位至关重要等特征时则应鼓励利用企业的纵向一体化,处于居间水平时,则应采取产权相对独立安排。
The construction of eco-industrial park is generally faced with the problem of low enthusiasm for enterprise participation and insufficient investment in eco-chain network construction. Therefore, according to the incomplete characteristics of eco-cooperation contract between enterprises in the park, the construction of eco-industrial chain eco-chain network is divided into pretreatment Asset investment process and commercialized asset investment process, this paper analyzes the causes of the underinvestment in the construction of eco-chain network in the park by using incomplete contract theory, and then analyzes the factors influencing the construction of ecological chain network in terms of policy intervention and property rights arrangement Incentive mechanism, and made the relevant policy recommendations. The research shows that: (1) asset specificity, production uncertainty, mutual trust and enterprise status in the recycle process of waste lead to the problem of underinvestment in the construction of eco-chain network in the park; (2) intervention of value subsidy only has participation Incentives and lack of investment incentives, the park should pay more attention to the application of investment subsidies; (3) When the waste has a large impact on the environment, the assets of the pre-reliance on the strong asset-dependent, emissions status of enterprises is essential and so on Encourage vertical integration of venting enterprises. On the contrary, when the park is in the initial stage of development, the commercialization value is high, the preconditioned assets are strongly dependent on the commercialized assets and the use of the status of the enterprise is of vital importance, the enterprises should be encouraged to use the vertical integration At intermediate level, relative independent property right arrangements should be adopted.
