乡村生态旅游促进新型城镇化的实证分析--以西安市长安区为例

在生态资源富集又邻近大城市的乡村地区发展乡村生态旅游,能够有效地促进新型城镇化、助推新型旅游小城镇的形成。文章在界定核心概念并进行理论机理分析的基础上,以西安市长安区为例,对其2002—2014年间乡村生态旅游与新型城镇化之间的关系进行实证检验,结果表明：二者确实存在高度的正相关关系,且前者是后者的重要原因。因此,应采取有力措施发展这些地区的乡村生态旅游：第一,进一步加大政府对乡村地区基础设施的投资,彻底实现城乡公共产品供给的均等化;第二,引导民间资金、技术、管理等有序合理、规模适度地投入乡村生态旅游业;第三,务必加强乡村生态旅游业发展过程中的环境监管等。     

Traffic density,congestion externalities,and urbanization in China

ABSTRACT

Although there is an abundant regional literature analyzing traffic congestion, only a few studies have explored extending such analysis with spatial effects. This study uses a dynamic spatial Durbin model and city-level panel data for the period 2003–14 to investigate the spatial spillover effects of traffic congestion on urbanization in China. The results show that there is an inverted ‘U’-shaped relationship between urbanization and traffic density in local and neighbouring cities, and congestion effects have appeared. In the short and long run, the spatial effects of traffic congestion have become an important force restricting the effective promotion of urbanization in China.     

城市化进程对基础设施投资的需求量分析

在分析基础设施投资需求构成的基础上,建立了相应的矩阵模型.并在对近十余年全国城镇人口和基础设施投资的数据进行统计分析和选取的基础上,按照一定的计算流程,通过拟合相关关系式、对原有基础设施投资(I0)进行估计、代入矩阵模型估算出未来的基础设施投资需求,从中得出了一些有价值的推论以供制定投资计划的决策者参考.

Creative Mediations of the City: Contemporary Public Art as Compass of Metro Manila's Urban Conditions

In this article, public art is proposed as creative agency mobilized to form urban imaginaries. These alternate visions are largely facilitated by artists and art collectives using urban communities as performative grounds. These projects promote a view of art as an effective channel for ‘recentering’ — the identification of a multitude of centers that endlessly fracture and shift, very much resembling the nature of cities themselves. An alternate vision of the city through cartography informed by contrast, temporality and ephemerality is proposed alongside dominant representations of the city. Works by artists Alma Quinto, Mark Salvatus and Wire Tuazon are representative examples of such strategies. Diverse in tactics and platforms, defined by site‐specific mediations, the projects facilitated by these artists reveal the uneven conditions that beset Metro Manila and its outlying areas. Quinto's altered Urban Plan/Duyan is the result of her engagement with women in an informal settler community in San Andres Bukid, Manila, while Salvatus's web‐based Neo‐Urban Planner is an astute observation of the obsessive yet futile ordering of people and space by the state. Tuazon's Amphibian installation is a commentary on the encroachment of multinational interests in local communities. These interventions are foils to state‐ and private‐led urban development schemes. Their strength lies in their direct engagement with the sphere of public dialogue and self‐determination. These artistic practices and strategies are shaped by community interaction, revealing that meanings residing in urban forms are relentlessly negotiated by the numerous actors that inhabit the city.

"拆迁上访"警示城市化过热

本文认为,造成"拆迁上访"的深层原因是城市化过热,让拆迁户背负了城市化的成本.城市化的实质是投资活动,应遵循投资的一般规则.要解决城市化过热的问题,需要政府把城市化当成社会化的市场化的投资活动,转换自己在城市化中的角色与职能,宏观调控微观放手,并在城市化中自觉接受民主监督与法律约束.     

关于我国征地制度问题的研究

城镇化作为农民职业转换、身份转变和社会价值观转型的载体,其健康发展成为解决中国"三农"问题的核心之所在。目前我国城镇化正处在发展推进期,传统的征地制度日渐显现出其内在的弊端,甚至蜕变为我国城镇化发展中的障碍因素。因此,有必要在廓清我国征地制度的变迁轨迹的基础上,剖析传统征地制度中存在的固有缺陷,为探明相应的制度变迁路径提供一种思路。     

城市化进程中政府行为研究

城市化发展的实践表明,政府在城市化进程中的作用是举足轻重的。在对城市化发展进行宏观调控、制定市场规则、提供公共服务等领域,政府行为的作用具有一定的不可替代性。但是政府在城市化发展中要摆正位置,把市场化作为城市化的第一推动力,实现政府与市场的互赢。
