建立产业共性技术研发外包博弈模型,从政府视角研究以共性技术产出最大化为目标的最优政府支持性研发外包合同,并对最优外包合同影响因素进行分析。研究表明:足够多的政府预算是共性技术政府支持性最优研发外包合同存在的前提,最优合同条款随政府预算的增大而增多,企业保留收益增大倒逼政府预算增加;企业最优知识技术投入与共性技术价值系数以及从研发中分享的收益份额正相关,与政府支付的固定研发费用负相关;政府最优知识技术投入与固定研发费用及单位投入成本系数负相关;企业最优投入与政府投入成本系数负相关,与政府投入对研发成功的贡献系数正相关,且企业最优投入随其研发能力的增强而加大。最后,根据研究结论,从政府预算、项目前景及支持性资源分配3个方面提出共性技术研发外包合同实施的政策建议。 相似文献

既有研发外包组织理论主要基于技术优势企业视角,关注如何治理技术溢出等交易成本,忽视了缺少专利和隐性知识的企业进行渐进性创新时最优研发外包组织选择。基于不完全合同视角,从企业对研发中激励代理方努力与降低渐进性创新的不完全替代性成本之间的权衡出发,分析委托方如何合作、并购、委托以及新建研发等组织最优选择。结果表明,当委托方技术水平较低时,最优组织将需要给代理方更多控制权以激励其努力,相反,委托方则保留更多控制权以降低不完全替代性成本。委托方市场规模通过影响代理方的私人收益降低不完全替代性成本,使得委托方愿意放弃控制权以激励代理方努力。新建研发可以看作是委托方通过承担更多时间和风险成本,从而降低不完全替代性成本。在不同组织形式中,委托方对研发投入的积极性是不同的,这决定了委托方通过研发外包获得的技术溢出效应和企业创新能力。 相似文献

Modelling Risk Perceptions of Stakeholders in Public–Private Partnership Toll Road Contracts 下载免费PDF全文
This paper investigates the risk perceptions of key stakeholder groups typically involved in public–private partnership (PPP) toll roads. Risk perceptions have an important impact on these PPP schemes for investing in public infrastructure. However, the nature and extent of risk associated with the specification of a PPP contract that commits contracting parties to deliver on their obligations remain unclear. In the context of major transport infrastructure, such as a new toll road, the often‐cited key risk to investors is the traffic (and hence demand) risk. There are, however, other risks, including political risk and media risk, the latter often causing untold harm resulting in modifications to the planned infrastructure. This paper develops a method to capture evidence on how public sector and private sector partners involved in previous PPPs perceive the levels of risk associated with each risk attribute, as a way of identifying the ex ante risk setting brought to negotiations in PPP toll road investments. Using a sample of 101 experts with contract experience in 32 countries, we develop a stated choice experiment and estimate a discrete choice model to quantify a risk profile index (RPI) to capture the perceived (relative) influence of each dimension of risk, and then identify sources of systematic differences in the RPI as a way of understanding the influence of personal traits and contextual and contractual factors. 相似文献

We investigate production risk, technical efficiency and risk attitudes amongst contract and independent farmers. We use a Bayesian parametric approach and stochastic dominance quantile regression methods to compare technical efficiency and risk attitude of smallholders in Nepal. Using farm‐level data, we find that contract farmers appear to show lower inefficiency and lower production risk. Additionally, contract and independent farmers can increase output by reducing the scale of operation. Regardless of the commodity produced and farming arrangement (contract or independent production), we find that labour, land and other inputs are risk‐augmenting, while the role of capital is mixed. We find a second order stochastic dominance (SSD) for lentils, and first order stochastic dominance (FSD) for tomatoes, ginger and HYV paddy seed commodities. Finally, contract farmers are more risk averse than independent farmers, regardless of the commodity produced. 相似文献

This research investigates the learning of inter-organizational contract design in greater depth. Two types of learning, i.e. learning from all past partnerships and learning from one specific partner, are distinguished in terms of their influence on the complexity of three different functions of the contract, namely control, coordination, and adaptation. Contract design capability and interorganizational routines are employed as mediators to explain the two types of learning respectively. Empirical tests using data from the Chinese construction industry reveal that there are significant indirect effects between partner-specific experience and contractual coordination, and between general partnership experience and all the three functions of the contract. This research contributes to the literature by providing more nuanced conclusions regarding the contract learning issue. 相似文献

This paper investigates if the strength of the legal system impacts on the trade in insurance and financial services in the high-income OECD and developing countries. Our findings reveal a statistically significant positive correlation of rule of law and regulatory quality with the exports and imports of insurance and financial services. Our empirical findings also reveal a negative and statistically significant correlation of contract enforcement with the exports and imports of insurance and financial services. We conclude that strengthening the rule of law and contract enforcement mechanisms can facilitate higher levels of trade in insurance and financial services. 相似文献

Nepal’s population continues to grow, but the agricultural sector’s performance remains almost stagnant. This has led to a decline in the per capita availability of food. Increasing agricultural productivity is the key to agricultural growth, and one strategy for increasing agricultural productivity is to use improved seeds. This study investigates the impact of contract farming (CF) in high yielding varieties (HYV) of paddy seed production on costs, yield, and profits of smallholder farms in Nepal. Using farm-level data and a non-parametric propensity score matching estimator, the study finds a significant positive impact of contract HYV seed farming on revenues, profits, and yield, and a significant negative impact on total costs of production. Additionally, very small farms (⩽0.43 ha) with CF in HYV paddy seeds tend to gain the most when it comes to yield per hectare. Our estimates reveal that the average smallholder household in Nepal engaged in CF with input conditions receives higher profits. However, farmers engaged in CF with output conditions tend to have higher yields but smaller profits. Finally, farmers engaged in CF in HYV paddy seeds with both input and output conditions have the highest yield gains and significantly higher profits. 相似文献

Perennial energy crops are a promising source of bioenergy whose production involves production risks, long‐term commitment of land and need for crop‐specific investments without the coverage of crop insurance potentially available for conventional crops. We conduct a choice experiment in five states in the Midwestern and South‐central regions of the U.S. to examine the effect of crop‐contract attributes on the joint discrete‐continuous choice decisions to adopt an energy crop and convert acres to it from a status quo use, while controlling for the effect of various farmers’ risk and time preferences, sociodemographic characteristics, and availability of crop insurance for conventional crops. We find robust evidence that high discount rates, high upfront establishment costs and need for crop‐specific investments create disincentives for adoption and allocation of land to energy crop production. The effects of riskiness of returns and risk aversion are less robust across specifications. The effect of conventional crop insurance on the energy crop adoption decision differs across types of insurance; in particular, farmers with revenue insurance are statistically significantly less likely to adopt an energy crop. Our results have implications for the design of effective contracts and policy incentives to induce the production of energy crops. 相似文献

This paper shows that a reciprocal grantback clause could potentially be a better licensing provision than a one-way type. There are two benefits associated with the use of a reciprocal grantback clause. First, it improves efficiency by reducing the (minimum) contract compatible royalty rate to zero. As a result, the production becomes efficient because both the licensor and the licensee produce at the same marginal cost. Second, a reciprocal grantback clause is a more effective provision than a one-way grantback clause to guarantee the transfer of superior technology, hence it promotes better technology diffusion. 相似文献
