基于风景健康的海南省自贸区人居环境 空间研究

海南经过30年的经济特区建设已正式迈入自贸区建设的新时代，所面临的地区发展与生态维育矛盾逐步加剧。为保育海南优良的生态品质，提升海南人居环境空间质量，基于“健康、生态、人居”三元耦合与互动多赢的发展关系，提出与之适宜的风景园林健康理论；结合前人经验，以人居环境空间规划为切入点，解析人居环境空间研究内容。运用ArcGIS 10.2.2空间分析和Fragstats 4.2景观格局分析，解析海南省域三生空间敏感性、资源利用效率可持续性，以及资源服务范围与开发建设空间适宜性，结合人居环境空间发展特征，提出从全岛国土空间、资源统筹和空间营造3个方面进行规划引导，并提出以下观点：1)人类活动对资源环境和空间利用的合理性是有效保障海南人居环境空间的前提基础；2)遵循风景园林健康理论指导的全域国土空间规划、资源统筹规划和空间营造规划是提升海南人居环境空间的根本路径；3)“健康、生态、人居”三元耦合和互动多赢的关系均衡与协调是提升海南人居环境空间的终极目标。     

特征尺度理论:经济学中的短期、长期与可持续发展

本文首先论述了特征尺度的基本概念，提出了特征时间尺度是可持续发展的基本时间测量单位的观点，利用特征尺度概念给出了经济学中长期与短期的定义，论述了它们与马歇尔长期与短期概念之间的区别与联系，详细讨论了特征尺度与战术和战略之间的关系，以及不同层次经济系统战略与战术之间的区别，联系与转化。     

The refoundation of the symmetric equilibrium in Schumpeterian growth models

We provide a refoundation of the symmetric growth equilibrium characterizing the research sector of vertical R&D-driven growth models. We argue that the usual assumptions made in this class of models leave the agents indifferent as to where targeting research: hence, the problem of the allocation of R&D investment across sectors is indeterminate. By introducing an “?-contamination of confidence” in the expected distribution of R&D investment, we prove that the symmetric structure of R&D investment is the unique rational expectations equilibrium compatible with ambiguity-averse agents adopting a maxmin strategy.     

Explaining momentum profits with an epidemic diffusion model

We show that information diffusion is a function of its dissemination and assimilation. Whereas dissemniation is a function of observable factors such as volume and price volatility, assimilation is dependent on unobservable factors such as the usefulness and reliability of information. We find that buying low volume (or low volatility) past losers and shortselling low volume (or low volatility) past winners generates a positive net return across the entire sample period and especially during bear markets. Second, buying high volatility past winners and shortselling high volatility past losers generates a positive net return, especially during bear markets.

区域经济增长理论与中国非均衡协调发展模式

区域经济发展中有均衡发展、非均衡发展和非均衡协调发展三种可选模式.区域经济的非均衡协调发展模式,强调在区域经济非均衡发展的同时,采取积极的方法,对这种不均衡进行适度的调控,以期实现区域整体经济的快速、健康和可持续发展.此模式已成为许多国家和地区经济发展的首选模式,也应是我国实现经济和社会可持续发展战略的首选模式.     

The contingent value of marketing strategy innovativeness for product development performance in Chinese new technology ventures

This study extends research on entrepreneurial behavior by investigating the relationship between the marketing strategy innovativeness (MSI) and new product performance in technology-based new ventures in China. Specifically, premised on contingent resource-based view we argue that MSI is a firm capability that must be bundled with external managerial relationships and be deployed in the appropriate environment to ensure its success. We found that the team's extra industry relationships and market dynamism enhanced the impact of MSI on new product performance. In contrast, top management team's intraindustry relationships, financial relationships, and technology dynamism hindered the impact of MSI on new product performance.     

A Reexamination of Housing Price and Household Consumption in China: The Dual Role of Housing Consumption and Housing Investment

It is important to investigate the correlation between housing price and household consumption to gain an understanding of the behavior of the economy and effectively handle the consequences of economic development. In the last two decades, the accumulation of housing wealth by Chinese households has not been effectively transmitted to their final consumption. We discovered that the sustained increase in household wealth and housing-ownership rate in China has been accompanied by a decrease in consumption rate. We also identified a negative correlation between housing price and household consumption for both the homeowners who own one housing unit and those who own two units of housing. We investigated this phenomenon in China both theoretically and empirically by capturing the dual nature of housing as a consumption good and an investment vehicle. We found that the demand for second housing units is motivated by increasing housing consumption demand rather than pure investment needs. To explain the mechanisms that drive household-consumption behavior, we also explored the effects on household consumption of China’s educational system, marriage market and ageing society, as well as future housing-market uncertainty. The implications of government intervention in the housing market are discussed.     

Supply chain finance schemes in the procurement of agricultural products

Product, information, and finance flows are all interrelated within the modern supply chain; thus, it is now more than ever of paramount importance for practitioners to integrate procurement and financial decisions. This challenge is exemplified in many agricultural supply chains, where operational risks are significant and access to capital differs sharply across firms. We study three management tactics that some large food/beverage manufacturers – situated downstream in these chains – have used to meet the challenge: ordinary fixed price contracts (or soft tolling) with direct suppliers, hard tolling and contract farming where the manufacturer intervenes upstream, providing capital, and coordinating procurement decisions. We place these upstream intervention schemes in the theoretical context of supply chain finance (SCF) and model their application to a three-echelon agricultural supply chain. We perform a numerical study in order to understand how the structure of capital constraints in the chain may influence the manufacturer's choice of SCF scheme. The numerical study is based on a business case that reflects the barley–malt supply chain of Heineken N.V. Despite greater coordination opportunities, we show that upstream intervention is not necessarily preferable for the manufacturer. Nevertheless, the preferred SCF scheme can be inferred on the basis of relatively simple characterization of the capital constraints in the supply chain.
