现代服务业是否有助于推动城镇化？——基于产城融合视角的PVAR模型分析

目前中国的城镇化现象难以完全用"工业决定论"来解释,服务业在城镇化过程中扮演着越来越重要的角色。流通业和旅游业作为现代服务业的主导产业,具有较强的集聚功能和就业吸纳能力,还具有较强的城市经济功能和服务功能,成为城镇产业体系和公共服务体系的必要组成部分。首先对服务业与城镇化之间的互动作用机制进行理论分析;然后建立PVAR模型,通过格兰杰因果检验、脉冲响应分析和方差分解分析变量之间的因果关系;最后构建耦合协调评价模型,从全国、区域及行业层面对系统间的相互作用强度与协调发展水平进行实证分析,并归纳协调发展模式。研究发现：以流通业、旅游业为主导产业的现代服务业与城镇化之间存在因果关系和稳定均衡关系,能够推动城镇化发展;早期由工业化推动的城镇化水平高于流通业和旅游业,后期两者逐渐缩减与城镇化的差距,系统间的耦合协调发展水平不断提升,但存在区域差异;耦合协调发展模式归纳为演化趋同型和发展同步型,发展同步型组合内各系统发展水平相对一致,有助于快速提升耦合协调发展水平。     

澳门土地制度改变及其影响与纱纸契合法性问题

澳门基本法第七条规定,澳门境内的土地和自然资源,除在澳门特区成立前已依法确认的私有土地外,属于国家所有。土地制度的改变、土地所有权的改变,除了涉及澳门土地所属问题,还涉及澳门特区的成立和基本法的实施对澳门原有法律制度和司法程序的影响。具代表性的案例是去年澳门特区终审法院就观音堂地段的所有权和使用权的民事诉讼案所作出的裁决:在特区成立前未获依法确认为私有的土地,特区成立后就成为国家所有,也不能通过司法裁判确认这些土地的所有权或利用权为私有,无论有关诉讼是在特区成立之前还是之后提起的。也就是说,澳门从此再也不会有新的私人业权土地了,连"和平占有"也不能了。土地制度改变所带来的影响,可从上述观音堂地段的官司反映出来,未来可能还涉及棘手的离岛土地"纱纸契"的法律地位问题。本文以终审法院的有关裁决为例,进而讨论土地制度的改变对于土地"纱纸契"问题的影响。     

Assessing the effects of land use and land cover patterns on thermal conditions using landscape metrics in city of Indianapolis,United States

Direct applications of remote sensing thermal infrared (TIR) data in landscape ecological research are rare due to limitations in the sensors, calibration, and difficulty in interpretation. Currently there is a general lack of methodology for examining the relationship between land surface temperatures (LST) derived from TIR data and landscape patterns extracted from optical sensors. A separation of landscapes into values directly related to their scale and signature is a key step. In this study, a Landsat ETM+ image of Indianapolis, Unites States, acquired on June 22, 2000, was spectrally unmixed (using spectral mixture analysis, SMA) into fraction endmembers of green vegetation, soil, high albedo, and low albedo. Impervious surface was then computed from the high and low albedo images. A hybrid classification procedure was developed to classify the fraction images into seven land use and land cover (LULC) classes. Using the fractional images, the landscape composition and pattern were examined. Next, pixel-based LST measurements were correlated with the landscape fractional components to investigate LULC based relationships between LST and impervious surface and green vegetation fractions. An examination of the relationship between the LULC and LST maps with landscape metrics was finally conducted to deepen understanding of their interactions. Results indicate that SMA-derived fraction images were effective for quantifying the urban morphology and for providing reliable measurements of biophysical variables. LST was found to be positively correlated with impervious surface fraction but negatively correlated with green vegetation fraction. Each temperature zone was associated with a dominant LULC category. Further research should be directed to the theoretical and applied implications of describing such relationships between LULC patterns and urban thermal conditions.

双循环驱动我国城市产业转移效应研究

基于201个城市的相关数据,利用动态面板模型和空间杜宾模型,实证分析了内循环、外循环和双循环对产业转移的影响。研究结果表明：前期产业转移在一定程度上会影响后期产业转移,前一期当地产业比例较大,其后产业转移受到的促进作用也较大;内循环、外循环和双循环均对产业转移起到显著的正向促进作用,东部城市受到的促进作用略高于中西部城市;要素流动在产业转移中发挥着重要作用,劳动力要素流动、技术要素流动和资本要素流动不仅受到内、外循环和双循环的促进作用,同时对产业转移也起到一定的促进作用;产业转移具有空间相关性,产业在空间上倾向于向产业转入较高的城区转移。为此,我国在政策上应进一步加快推动内循环,促进外循环,关注要素流动在产业转移中的重要作用,合理分配要素资源。     

诠释的循环及实践维度批判

循环性是诠释的基本特征之一.文章用马克思主义观点分析了循环的动力、实质、作用和特征,由此指出诠释内部存在的相信社会进步和不相信社会进步两种观点的自相矛盾之处,最后对如何走出诠释学循环的魔圈,尝试作出根本性回答.     

招贴设计的方法论研究

招贴设计的方法论研究是平面设计基础理论的一个重要支系,由于招贴设计自身的复杂性,与之对应的方法论研究不应等同于一般的设计方法论.文章突破了旧有的研究体系,尝试从哲学、图像学、潜意识等多个角度去剖析创意生成的奥秘,进而引导初学者完成创意的构思.     

Changing Indigeneity Politics in Indonesia: From Revival to Projects

Through the discourse of indigeneity, rural communities around the world are joining a global network of rural justice seekers. By articulating grievances collectively, they demand state recognition while seeking support from NGOs and international development organisations. In Indonesia, the manifestation of indigenous ‘adat’ politics is no longer confined to the national struggle for the recognition of land rights, but instead, has proliferated into many localised short term ‘adat projects’. This introduction to the TAPJA special issue on adat demonstrates that both the rural poor and local elites can be the initiators or recipients of these adat projects but, at the current juncture, the latter are better positioned to benefit from such projects. The special issue shows that in Indonesia, where adat is often firmly entrenched in the state, the promotion of indigeneity claims can work in contradictory ways. Findings from across the special issue show that adat projects tend to reinforce the power of the state, rather than challenging it.

浅析房地产市场复苏的制约因素及其对策

房地产市场包括一级市场和二级市场，二级市场又包括消费市场和投资市场。现在的政策导向只注重房地产消费市场部分，而忽视了其投资市场部分，这是潜力巨大的市场。房地产只有真正成为大众投资品种时，才可能促进房地产一、二级市场的共同繁荣     

浅谈创新农村土地流转模式与农民意愿问题——基于典型创新土地流转模式的实证考察

在我国土地公有制的背景下,通过在土地所有权的基础上设立(如土地承包经营权和宅基地使用权等的)用益物权,解决了土地的归属与利用的矛盾。在我国土地制度改革的进程中,农村土地承包经营权也在通过多种方式开放流转。关于土地流转方式的创新模式也在各地展开的探索。作者通过对三种典型的创新土地流转模式进行实证考察,结合基本理论研究,进而对创新土地流转模式展开讨论。以农民意愿作为基本价值判断,指出创新土地流转模式在制度设计上存在的问题。
