党的十九届五中全会提出了到2035年人均GDP达到中等发达国家水平的远景目标,因此测算和回答能否和如何如期实现该目标,对于我国实现第二个百年奋斗目标和坚持“四个自信”具有重要的意义。为此,本文根据跨越和陷入“中等收入陷阱”经济体的发展经验,对2021—2035年我国潜在增长率变化进行了测算。一是参照跨越和陷入“中等收入陷阱”经济体在我国相同发展阶段时各主要生产要素的变化,模拟设定我国未来各主要生产要素的增长率;二是通过运用附加人力资本的增长核算模型测算基准、乐观和悲观三种不同情境下未来我国经济的潜在增长率,验证我国2035年发展目标实现的可能性;三是依据主要要素对潜在增长率的贡献度,提出我国如期实现2035年发展目标的相应政策建议。 相似文献

基于限制因素组合序列的耕地质量提升潜力研究*——以什邡市为例 总被引:5,自引:0,他引:5
[目的]通过分析什邡市耕地质量现状,充分把握影响耕地质量的主导因素并进行质量提升分区,测算不同质量提升区的提升潜力,以期为全市耕地质量的建设与发展指明方向。[方法]依据农用地分等理论,构建2014年什邡市耕地质量限制性指数评价体系,采用限制性指数模型测算耕地质量限制性指数,结合因素组合法、耕地质量潜力测算法,分别进行耕地质量提升分区及其提升潜力评价。[结果]什邡市耕地质量现状差异显著,地域分布特征明显;因素限制程度以中限制为主,多因素共同主导限制耕地比重大;各质量分区限制特征明显,各区耕地质量提升潜力在时序上和空间上也存在差异。高等别耕地集中分布于南部平原,受土壤酸碱度中等限制和剖面构型高程度限制为主;北部丘陵区以及南部河谷低洼地带主要为低等别耕地,表现为坡度与灌溉因素较高程度限制为主;综合提升潜力较大的耕地集中于北部丘陵区与南部河谷低洼地带。[结论]什邡市范围内耕地质量差异明显,存在普遍限制且分区限制特征明显,各区提升潜力空间差异明显。 相似文献

AbstractThe current economic crisis has brought to the fore the need for firms to deal with ambiguity and complexity. Hence, firms need a specific balance between exploration and exploitation in order to keep pace with varying and changing environmental conditions. Hitherto, there is limited research that has examined the nexus of HR architectures, ambidexterity, and environmental dynamics. In this conceptual paper we ask: How do HR architectures serve as a means of balancing exploitative and exploratory learning in different dynamic environments? We explain how exploratory, exploitative, and ambidextrous HR architectures with their embedded HRM systems on the business unit level enable organizations to meet different environmental requirements. Thus, firms in which heterogeneous demands for flexibility and for innovation co-exist need to develop internally differentiated HR architectures. In particular, we elucidate how critical the organization’s ability is to connect different HRM systems to create an ambidextrous HR architecture to find an appropriate balance between exploration and exploitation. 相似文献

Given the increasingly strategic role of external resources, acquiring knowledge about current suppliers and the broader supply market is an important and demanding task for the purchasing and supply management (PSM) function of a firm. Performance-improvement-oriented application of external supply knowledge present further challenges for the function. To examine this, we draw on the knowledge-based view and develop a hypothesized model in which supply knowledge acquisition drives PSM exploration and exploitation orientations which in turn mediate the organizational status of PSM function in terms of supply performance. We test the model on an SME-focused and survey-based dataset, using structural equation modelling. Our results indicate that an exploitative orientation is associated with knowledge gained from the supply base, whereas an explorative orientation is predominantly associated with supply market knowledge and less with supply base knowledge, suggesting natural pairings. The findings also show how an exploitative development orientation mediates the positive association of the PSM function's organizational status with supply performance. Driven by supply base knowledge, a status-empowered exploitative PSM orientation may suppress supply market based explorative orientation in resource-scarce SMEs, thus appearing to serve as the sole path to supply performance. Our research contributes by pointing out the significance of the knowledge-resource, and the knowledge-based view, in understanding performance in PSM. 相似文献

ABSTRACT In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory. 相似文献

Employees are increasingly given control over how they learn, and their choices for training are diverse and varied, yet employees must balance competing demands. On one hand, they are expected to be increasingly efficient in their current job duties – on the other hand, they are expected to develop new skills and competencies that enable them to adapt and respond to changing job demands. Drawing from the organizational learning literature, we propose a model of worker and work characteristics that inform choices between two mindsets related to learning at work. The first mindset is exploration, or the pursuit of learning outside one’s current knowledge domain; the second mindset is exploitation, the refinement/deepening of one’s existing knowledge stock focusing on the task at hand. We further propose that these strategic choices, or trade-offs, influence employee learning and performance in unique ways, with different implications for both routine and adaptive performance. Finally, we incorporate the notions of feedback loops and risk assessments that influence ongoing decisions between exploration and exploitation mindsets. Recommendations for future research and extensions of the theoretical model are also proposed. 相似文献

Understanding customer needs is key for fashion retailers to stay competitive and innovative. Surprisingly, however, extant literature mainly explores customer needs in terms of a garment and its attributes rather than viewing shopping as a problem-solving process to meet customer needs. Moreover, these studies fail to address how customers meet their needs in-store (ISFR) and online fashion retailing (OFR). To fill this research gap, we empirically investigate customers' personal and social needs and how they can be met through the jobs-to-be-done theory. Findings reveal that, beyond the purchase of a garment, customer needs can be fulfilled through different ways, such as smart technology or a person's high interaction with social others in ISFR and the online shop experience or a social linkage without social interaction in OFR. Additionally, our findings offer potential service innovations for fashion retailing managers. 相似文献
