采用SBM-Undesirable模型测算了1999—2017年中部六省的碳排放效率,分别计算了产业结构合理化指数和高级化指数,利用耦合协调模型考察了碳排放效率与产业结构优化的耦合协调度,并对其影响因素进行了实证分析。结果表明:中部六省碳排放效率和产业结构合理化的耦合协调度较低,处在中度失调和中度协调之间,碳排放效率和产业结构高级化的耦合协调度处在中度失调和中度协调之间,但有明显上升的趋势。人力资本、财政支出对中部六省碳排放效率和产业结构合理化的协调发展起到了促进作用,而环境规制、能源结构产生了抑制的作用。人力资本对碳排放效率和产业结构高级化的耦合协调度有正向作用,而外商投资、人均资本、制度质量和能源结构产生了抑制作用。 相似文献

Consumers often base their judgments on a no-pain, no-gain principle—that is, one must pay a cost in order to achieve a beneficial outcome. For example, they infer the quality of a product from its price and judge a bad-tasting medicine to be more effective than a tasty one. Although the use of this principle to infer the value of a product or service has been observed in several domains, the processes that underlie its use have not been fully explored. We find that when people feel out of control, they tend to use the principle because it exemplifies a causal relationship between actions and outcomes and endorsing it reaffirms their belief that they have control over the outcomes of their behavior. Our findings have implications for how marketers might position products and services to attract consumers who perceive themselves as having different levels of control. 相似文献

In this paper, we consider factor models of the term structure based on a Brownian filtration. We show that the existence of a nondeterministic long rate in a factor model of the term structure implies, as a consequence of the Dybvig–Ingersoll–Ross theorem, that the model has an equivalent representation in which one of the state variables is nondecreasing. For two‐dimensional factor models, we prove moreover that if the long rate is nondeterministic, the yield curve flattens out, and the factor process is asymptotically nondeterministic, then the term structure is unbounded. Finally, we provide an explicit example of a three‐dimensional affine factor model with a nondeterministic yet finite long rate in which the volatility of the factor process does not vanish over time. 相似文献

文章以代理理论为基础,实证分析激励和监督对经销商依从的影响及依赖结构的调节作用。研究发现:激励会促进经销商依从,而监督则会抑制经销商依从;相互依赖强度会削弱监督对经销商依从的负向影响,但对激励与经销商依从间的关系没有显著影响;经销商相对依赖会增强激励对经销商依从的正向影响,但对监督与经销商依从间的关系没有显著影响。文章最后对研究发现进行讨论,并提出管理建议和未来研究的方向。 相似文献

The “50/50”, or the shared management international joint venture (shared IJV) remains a popular and yet challenging control structure to govern IJVs. The purpose of this study is to understand the post-formation management of shared IJVs, specifically the relationship between shared structure, relational conditions and management of post-formation challenges. Our evidence is based on 26 in-depth interviews across four cases of shared IJVs between British multinationals and Asian companies. Our findings indicate that the highly integrative nature of shared IJVs, including high operational interdependence and shared decision-making, encourages partners to work closely together, communicate frequently and intensely and exchange personnel. Although share management can lead to inter-partner conflicts, the equal investment and mutual responsibility partly provides partners with motivation and opportunities to learn about each other, to better implement the control structure, to build trust, and to commit to the venture and partner. These relational conditions facilitated the successful management of post-formation challenges such as diversity related conflicts and macro volatility. 相似文献

The conventional partial adjustment model, which focuses on leverage evolution, has difficulty identifying deliberate capital structure adjustments as it confounds financing decisions with the mechanical autocorrelation of leverage. We propose and estimate a financing-based partial adjustment model that separates the effects of financing decisions on leverage evolution from mechanical evolution. The speed of adjustment (SOA) is firm-specific and stochastic, and active targeting of capital structure has a multiplier effect that depends on the size of financial deficit. Overall, we find expected SOA from active rebalancing (30%) more than doubles what is expected from mechanical mean reversion alone (13%). 相似文献

本文以制造业上市公司为研究对象,从收入动因成本中分解出收入动因固定成本和收入动因变动成本,进而计算出习性成本结构指标、保本点指标以及经营安全程度(安全边际率)指标。通过习性成本结构和经营安全程度分析可以得出以下研究结论:(1)以收入动因成本和营业净收入为基础进行的习性成本结构和经营安全程度分析是合理的、可靠的;(2)制造业整体上变动成本比重较高,行业整体营业净收入中变动成本比重为89.44%;(3)制造业整体经营风险较低,行业整体安全边际率为77.71%,处于“很安全”的范围。 相似文献

[目的]为促进水库移民的生计恢复及转型,探寻就业结构和土地流转间的交互机制,分析两者间耦合作用对当前移民安置模式及政策的影响。[方法]文章从移民就业结构变迁出发,通过超边际理论构建了安置区移民土地的流转机制模型,推演了从业决策对土地流转行为的影响路径,并运用南水北调农业安置移民数据进行实证检验。[结果]大面积转出土地是移民搬迁后土地处置的主要行为,移民中土地转入户有所增加,但土地集中度却有所减少。移民非农就业较搬迁前有明显上升,并有向当地兼业转移的趋势,但与土地流转间并不互为因果,农村社保还难以弱化其对土地养老的依赖。劳动力数量、非农就业时间、非农收入占比、土地政策等对移民土地流转行为和规模均有显著影响,而外出就业前景和地租水平在促进土地流转行为的同时,却不一定能增加土地流转面积。[结论]移民外迁中可以采用无土安置代替农业安置,推动移民土地流转的关键在于技能培训、政策保障和地租补贴,简单的就业推荐和土地权属划分的作用有限。而对于移民中的农业大户,则需在满足土地转入面积的基础上,保障其在安置区的各项土地权益。 相似文献

This article argues whether and how investment promotion agencies (IPAs) efficiently influence investment promotion in the cases of the following selected variables: resources (experience, total staff, and overseas staff), service functions (combined promotion service of inward investment and trade, and inward and outward investment), and organizational structure (autonomous status of private/upper ministry-level IPAs). The results reveal a positive relationship between IPA’s performance and longer experience, larger staff, larger overseas IPA staff members, autonomous private agency types, and upper ministry-level IPAs. However, an IPA’s performance was negatively associated with the combined promotional service of inward investment and trade, and inward and outward investment. The results suggest that an IPA’s performance can be enhanced by adjusting the service functions and restructuring the governance and structure in addition to improving the IPA’s resources and the country’s investment climate. 相似文献
