‘To sell or not to sell’: Licensing versus selling by an outside innovator

We study various modes of technology transfer of an outside innovator in a spatial framework when the potential licensees are asymmetric. In addition to different licensing options, we also look into the option of selling the property rights of innovation and find the optimal mode of technology transfer. For licensing we find the optimal policy is to offer pure royalty contracts to both licensee firms when cost differentials between the firms are relatively small compared to the transportation cost, otherwise offer a fixed fee licensing contract to the efficient firm only. Interestingly, we show the innovator is always better-off selling the innovation to any one of the firms who further licenses it to the rival firm. The result holds irrespective of the size of the innovation (drastic or non-drastic) and the degree of cost asymmetry between the licensees. Social welfare is greater under selling than licensing.     

City Size,Population Concentration and Productivity: Evidence from China

This paper investigates the impact of China's city size and urban population concentration on city productivity by developing a distinctive index based on global nighttime light data. Using the panel data of 280 prefecture cities from 2004 to 2013 and employing dynamic system generalized method of moments and panel threshold model regression techniques, our results show that city size has a positive impact on city productivity; therefore, cities in China still have the potential to expand. While moderate urban population concentration can benefit city productivity, excessively concentrated urban population distribution may impede the growth of city productivity. We also find that the level of labor income significantly affects the impacts of urban agglomeration on labor productivity. Therefore, our results imply that city development policies should focus more on how to appropriately allocate economic activities and adjust population distribution in urban areas according to different stages of economic development.     

旅游发展对城市工业化的影响及其差异性研究——以58个旅游城市为例

文章构建了旅游业发展影响工业化的理论模型，并利用2000—2016年中国58个旅游城市面板数据和动态面板模型，从总体、专业化、规模和区域等多维度，分析检验了旅游业发展对城市工业化的影响及差异性。结果表明：无论是宏观层面，还是三种分类检验，旅游业发展对城市工业化都具有负向效应。当前，中国旅游城市存在一定的“旅游诅咒”效应，阻滞了其工业化深化；分专业化研究可知，旅游业发展对工业化的负向作用，由大到小依次为旅游高专业化、低专业化和半专业化城市；分规模研究发现，中型旅游城市的最显著，小型旅游城市次之，而大型旅游城市最不显著；分区域研究表明，中西部旅游城市的较突出，而东部旅游城市统计上并不显著。这为各个旅游城市采取有效措施及时防范和规避“旅游诅咒”效应和正确处理“旅游业+工业化”关系提供了参考依据。     

平顶山市休闲农业不同区域的发展潜力评价

[目的]对平顶山市休闲农业的空间分布特征及其发展潜力进行分析和评价,以期为平顶山市休闲农业的可持续发展提供参考和借鉴。[方法]文章对平顶山市休闲农业空间布局分区论述,并采用层次分析法构建平顶山市休闲农业发展潜力指标评价体系,确定指标权重,然后根据各指标的游客和当地农民的打分值与权重值加权计算不同区域的发展潜力指数并比较发展潜力大小。[结果]根据区域位置和地理环境以及休闲农业发展速度,将平顶山市休闲农业划分为北部山区休闲农业区、东部城乡休闲农业区、南部现代休闲农业区和西部傍水休闲农业区4个区域,各区域发展特点突出。对各指标权重值与打分值的加权求和计算得到的不同区域发展潜力指数看出,西部傍水休闲农业区的发展潜力最大,其次为北部山区休闲农业区,再者是南部现代休闲农业区,东部城郊休闲农业区的发展潜力最小。[结论]平顶山市休闲农业发展前景广阔,具有可持续发展的巨大潜力。由于地理区位和交通基础设施建设及环境条件和农业基础的差异,平顶山市的休闲农业可分为东西南北4个发展区域,其中西部傍水休闲农业区和北部山区休闲农业区具有较大的发展潜力,平顶山市可将其作为重点发展对象,重点打造水岸和山村休闲农业游,借助发展优势突出区域特色。     

Making the ‘Invisible’ Visible: Redevelopment‐induced Displacement of Migrants in Shenzhen,China

Gentrification in China is intertwined with urban redevelopment, which causes the large‐scale displacement of rural–urban migrants from ‘villages in the city’ (ViCs). Because of the informality of ViCs, migrant renters have very insecure tenancy and during redevelopment they are treated as a negligible (‘invisible’) social group. As they are very difficult to locate after displacement, they are also literally invisible to researchers. To make the invisible visible, this study traced a sample of displaced migrants from Huangbeiling village in Shenzhen. The focus was on the displacement process and on identifying the consequences for the displaced. We found various forms of displacement during the redevelopment process. Nearby ViCs were prioritized by displaced migrants to minimize as much utility loss as possible. However, they generally suffer from decreased proximity, increased living costs, and the loss of social networks and job opportunities. Remarkably, some choose to return to the gentrifying village, enduring displacement in situ caused by increasing rents, drastic physical neighbourhood changes and declining liveability, in exchange for retaining their original social and economic networks. Large‐scale urban redevelopment is causing the rapid shrinkage of informal housing. Recognizing and addressing the housing needs of this impoverished social group is a matter of urgency.     

衡水市农户土地资源转出意愿的影响因素与行政干预

[目的]通过了解河北省衡水市农户土地转出的意愿状况,分析影响农户土地资源转出意愿的关键因素,并制定正确的战略决策,为构建农地适度规模化经营奠定理论基础,促进衡水市农民的现代化发展。[方法]文章结合调研情况,对样本区农户土地使用权流转行为进行了统计描述和分析研究,并运用Logistic模型对农户土地使用权转出意愿的影响因素进行了分析,找到了影响衡水市土地流转的关键性因素。[结果]研究表明,户主年龄、从事职业和文化程度、农户家庭非农收入以及农户家庭兼业人数等与农户土地转出意愿呈显著正相关关系,显著性数值分别为0. 018、0. 000、0. 010、0. 000、0. 028,而农户家庭农用机械数量则与农户土地转出意愿呈显著负相关关系,显著性数值为0. 033。此外农户社会保障程度和农户对政府土地流转的相关政策了解程度等因素也影响着农户土地流转的意愿。[结论]影响农户土地转出意愿的显著性因素包括家庭非农收入、户主年龄和职业;另外,户主的年龄、职业、文化程度、非农收入、家庭兼业人数和农用机械数量均是影响农户土地转出意愿的重要内容。     

Effects of non-aeronautical activities at airports on the public transport access system: A case study of Zurich Airport

Many planning authorities and airports study measures to increase public transport use for airport ground access and egress. At the same time, an increase in real estate development at and around airports is occurring, both due to airports seeking new revenue possibilities and other developers attempting to profit from high value locations. This paper considers non-aeronautical activities at large airports, largely commercial centres and transit hubs, as land uses that have the potential to improve the situation for operating public transport services. In order to assess potential benefits and disadvantages, four research questions are considered: (1) Can the additional travel volume reach levels at which it has a significant impact? (2) To what extent do non-aeronautical activities influence the public transport access system? (3) Is the resulting demand distribution better or worse regarding peaking behaviour? (4) Is there a potential for the resulting overall demand to bring about capacity shortages?A case study is conducted at the airport of Zurich, Switzerland, which finds that non-aeronautical activities in the direct airport vicinity have led to a situation where the operation of public transport services is much more viable due to overall higher passenger numbers and a more even distribution throughout the day. It is concluded that locating non-aeronautical activities at airports can, in addition to providing commercial benefits to developers, lead to a situation where improved public transport services become feasible.
