土地领域供给侧结构性改革的重心和方向

研究目的:分析土地领域供给侧结构性改革的本质,研究提出土地领域供给侧结构性改革的重心和方向。研究方法:基于微观经济学和土地经济学理论,结合中国推进供给侧结构性改革的战略和实践,从中国土地市场的特殊性入手,分析中国土地市场供需信号传导、市场主体构成和市场供需平衡,探求推进土地领域供给侧结构性改革的路径。研究结果:(1)地方政府成为土地市场中的主体并发挥主导作用,形成了中国土地市场的特殊性。政府与市场的进退,关键考量是政府对土地市场的把控能力能否优于建设一个相对竞争充分的土地市场。(2)土地市场供需信号失灵的原因,主要来自于土地要素让渡市场,一方面市场失灵导致企业追求高利润过滤真实需求信号而不受市场之制,另一方面地方政府市场定位放大市场有偏信号,两者共振,形成土地市场整体的有偏预期,共同引起土地市场失衡。研究结论:推进土地领域供给侧结构性改革,(1)关键是引导土地市场向满足公众真实需求的方向转化、生产企业向转变生产方式和发展方向的转变;(2)重点是逐步实现土地征收市场与土地让渡市场的对接,实现土地供需信号畅通传导并有效指导企业开展满足公众需求的生产活动;(3)方向是弱化政府在土地要素让渡市场和征收市场中的市场主体地位,强化并发挥政府在土地市场中的管理、监督和调控的作用;(4)途径是继续强化和充分发挥政府在土地规划、土地市场、土地供应、农地制度改革中的规制作用。     

Why has China’s vertical specialization declined?

Vertical specialization (VS) is quantified by the VS share, which measures the average import content per dollar of exports. A characteristic of China’s export trade is its strong dependence on assembly and processing activities. To take proper account of this, China’s VS shares should explicitly distinguish processing export production from other production. We estimate China’s annual VS shares from 2000 to 2012—the latest year for which a special input–output table is available that makes such an explicit distinction. We find that VS shares increased from 2000 to 2004 and subsequently started to decrease. To explore why it has declined, we introduce a new structural decomposition approach. We find that the decrease of the VS share appears to have been driven mainly by the substitution of imported intermediates by domestic products. This occurred in particular in the production of exports, which implies an upgrading of China’s position in global value chains.     

Chinese tourists' views of nature and natural landscape interpretation: a generational perspective

This study investigates Chinese tourists’ views of nature, interest in animal experiences and their preferred natural landscape interpretation content from a generational perspective. Eight hundred and eight self-administered questionnaires were collected at Wulingyuan, a UNESCO World Natural Heritage Site, in China. It suggests that overall Chinese traditional cultural values and beliefs, notably the thinking of tian ren he yi (oneness of nature with humans), still have considerable impacts on Chinese tourists. They were found to have a strong sense of connection with nature and a preference for cultural interpretations of natural landscapes. Meanwhile, Chinese might be reaching a point of convergence in terms of attitude towards nature and animals with their Western counterparts, as reflected by their weak anthropocentric view, and strong ethical and aesthetic appreciation of animals, regardless of generation cohorts. Yet, the study shows significant generational gaps: older generations have a stronger connection with nature, are more concerned about environmental issues and show more support for the Western approach towards nature protection; the younger generations hold weaker anthropocentrism, and are more interested in animals, yet are less likely to learn about nature through tourism interpretation.     

Key impact factors of visitors’ environmentally responsible behaviour: personality traits or interpretive services? A case study of Beijing’s Yuyuantan Urban Park,China

The environmentally responsible behaviour (ERB) facilitates the sustainability of tourism destinations. This study aims to identify the key impact factors to promote visitors’ ERB in urban park and examine the impact mechanism. A total of 567 visitors were surveyed in Beijing’s Yuyuantan Urban Park. Structural equation modelling results indicate that personality traits are the most important factors that affect visitors’ ERB, while the effect of how satisfaction with interpretive services plays upon visitors’ ERB using place attachment as a mediator. Openness traits positively affect satisfaction with experiential services and general behaviour. Additionally, implications in urban park management are provided.     

The influence of attitudes towards healthy eating on food consumption when travelling

This study explores tourists' attitude towards healthy eating and its influence on their travel eating behaviour. Based on focus group interviews and literature review, two instruments were developed to measure healthy eating attitude and travel eating behaviour. Factor analysis results revealed two healthy eating attitude factors (‘food content and nutrients’ and ‘balanced diet and eating habit’), and five travel eating behaviour factors (‘novelty’, ‘risk avoidance’, ‘health steadfastness’, ‘familiarity’, and ‘food supplement and medicine’). The relationships among the factors were examined using structural equation modelling. The findings revealed that respondents who had a stronger attitude towards ‘balanced diet and eating habit’ tended to be more motivated by the ‘novelty’ factor; whereas ‘risk avoidance’, ‘health steadfastness’ and ‘familiarity’ were found to be associated with a stronger attitude towards ‘food content and nutrient’. The findings suggest that the healthy eating attitude construct is multidimensional and healthy eating conscious tourists should not be treated as a homogeneous group.     

奥贝胆酸有关物质的分析及合成

为了控制奥贝胆酸药品的质量,从奥贝胆酸原料药中分离并鉴定了3种有关物质:3α-羟基-6-乙基-7-酮-5β-胆烷-24-酸(A),3α,7α-二羟基-6-亚乙基-5β-胆烷-24-酸(B)和3α(3α,7α-二羟基-6α-乙基-5β-胆烷-24-酰基氧基)-7α-羟基-6α-乙基-5β-胆烷-24-酸(C)。分析了这些物质产生的原因并进行了设计合成,其结构经过核磁共振氢谱得以确认。研究表明,3个有关物质与奥贝胆酸粗品中的主要有关物质的相对保留时间完全一致,合成的有关物质与分离得到的有关物质的核磁共振氢谱图相符合,可以判定奥贝胆酸产品中的主要有关物质就是合成得到的有关物质A、有关物质B、有关物质C。解决了有关物质研究所需对照品的问题,提高了原料药的质量,为奥贝胆酸的质量研究和有关物质的控制提供了一定的帮助。     

我国经济结构失衡的内需与外需原因分析

我国已是一个经济大国,内需应是经济增长的主导力量。外需快速增长给我国央行货币发行与管理模式的有效性带来挑战,使我国经济结构失衡加剧,不利于实现经济增长向内需主导型模式的转变,也不利于经济发展水平与国内居民消费水平之间做到良性循环。要建立起以内需为主导的经济发展模式,就必须促进经济增长由主要依靠投资、出口拉动向依靠消费、投资、出口协调拉动转变,这是我国实现经济长期、持续、协调发展的必然要求,也是贯彻落实科学发展观的重要体现。为此,文章在分析我国经济结构失衡原因的基础上,提出通过进行出口战略性调整,＂消解并转移＂过度的外汇储备,把经济发展模式转变与政府促进公共消费联系在一起,以此作为有效扩大内需的一种调控手段。     

研发投入、新兴资本与企业绩效关系探讨

文章以2012年我国上市公司年度报告为研究样本,应用AMOS结构方程软件,实证分析了研发投入、新兴资本与企业业绩的相互关系。研究表明,研发投入对新兴资本、新兴资本对企业业绩都具有显著的促进作用。企业要实现持久的业绩提升,必须转变新兴资本筹集渠道。自主研发应成为新兴资本最主要的获取途径,并且还需进一步调动研发人员积极性,促进研发费用向开发支出以及新兴资本的转化,并进一步加强新兴资本间的内部整合,提高新兴资本的投入效率。     

区域发展战略对能源消耗的影响研究——新结构经济学视角

基于新结构经济学理论,对区域发展战略与能源消耗的关系进行理论和实证分析。理论分析发现,违背比较优势的区域发展战略使得人均能源消耗增大。进一步地,利用我国1997-2019年的省级面板数据进行实证检验,在选取老工业基地数量作为区域发展战略的工具变量等内生性处理和稳健性检验后,实证结果支持上述理论假说。异质性分析发现,处于不同发展阶段的地区,区域发展战略对能源消耗的影响不同。进一步讨论发现,违背比较优势的区域发展战略还会导致能源库兹涅茨曲线的第二个拐点延后,峰值也将变大,阻碍能源库兹涅茨曲线的收敛。为实现人与自然和谐共生的“中国式现代化”,建议政府采用符合比较优势的的地区发展战略,并大力支持创新和相关人才的培训以及继续教育工作。
