Policy Analysis of Agricultural Water Fee Collection in China

AbstractThe low collection rate of agricultural irrigation water fee is a common problem facing many developing countries, which has also troubled China since the 2000s. In different areas of China, there are two problem-solving strategies: raising water collection rate or exempting water fee. In this paper, we analyze the dilemma of China's agricultural water fee collection from both practical and theoretical perspective. We argue that China will not follow up one single model in agricultural water fee collection and each local government should explore appropriate policy in line with their own situation

Air Transport Services in Regional Australia – Demand pattern, frequency choice and airport entry

This study investigates the development of the aviation market at Australia’s top 50 regional airports during 2005-2013. Demand estimation results suggest that a higher commodity price increases traffic volume in markets where the local economy heavily relies on mineral resources and that an appreciation of the Australian dollar decreases passenger flows in tourism-dependent areas. The presence of leading airlines and low-cost carriers, and the availability of international services all contribute positively to market growth. Airport entry analysis reveals that major carriers engage in clear strategic interactions. The Qantas airline group has used Jetstar as a fighting brand, thus that Jetstar flies to a destination if and only if the regional airport is also served by Virgin Australia, the group’s major competitor. Unlike routes connected to major airports, demands in regional airports are not sensitive to flight frequency, but seem to be positively influenced by national fare levels. Our empirical results support a consistent aviation policy across Australia, especially for issues related to airline competition and demand stimulation. However, special considerations need be made for regional airports to help them to deal with economic shocks and cover fixed costs

Pancake bouncing on superhydrophobic surfaces

Engineering surfaces that promote rapid drop detachment is of importance to a wide range of applications including anti-icing, dropwise condensation6, and self-cleaning. Here we show how superhydrophobic surfaces patterned with lattices of submillimetre-scale posts decorated with nano-textures can generate a counter-intuitive bouncing regime: drops spread on impact and then leave the surface in a flattened, pancake shape without retracting. This allows for a four-fold reduction in contact time compared to conventional complete rebound. We demonstrate that the pancake bouncing results from the rectification of capillary energy stored in the penetrated liquid into upward motion adequate to lift the drop. Moreover, the timescales for lateral drop spreading over the surface and for vertical motion must be comparable. In particular, by designing surfaces with tapered micro/nanotextures which behave as harmonic springs, the timescales become independent of the impact velocity, allowing the occurrence of pancake bouncing and rapid drop detachment over a wide range of impact velocities.Comment: 11 pages, 4 figures, 31 references, + 5 pages of supplementary informatio

The decline of canal irrigation in China: Causes, impacts and implications

Irrigation is key for agricultural production and public affairs in China. Canal irrigation has been the dominant form of irrigation in China for over two thousand years, but this is changing dramatically in contemporary China. Official government data and observational studies prove that canal irrigation has sharply declined in China in the past several decades. This paper explores the causes and influences associated with this decline. We use the social-ecological systems (SES) framework to diagnose the causes of the decline of canal irrigation and identify the significant influences on it. The broader contextual variables of industrialisation, urbanisation, policy, marketisation and technological progress influence resource systems, farmers and governance systems, which, in turn, have jointly led to the decline of canal irrigation. This study also considers the economic, social and ecological consequences of such a shift in irrigation pattern. The decline of canal irrigation may be inevitable in the transformation from a rural to a modern society. However, we must be aware of its costs and risks. To maintain the effectiveness of rural irrigation during the transformation to a modern society, we propose three implications of the decline of canal irrigation

Understanding airline price dispersion in the presence of high-speed rail

This paper examines the price dispersion among China's “Big Three”, namely, Air China, China Eastern and China Southern in the presence of high-speed rail (HSR). It has been found that HSR is positively and significantly associated with airline price dispersion on the long-haul routes, which may suggest that the presence of HSR can facilitate airline cooperation in setting prices and outputs, thereby leading to greater price dispersion. However, on the short-haul routes where HSR is highly substitutable, the HSR competition effect dominates, and smaller price dispersion is observed. All the market structure and competition variables included in this study support the conclusion that price dispersion is greater in more concentrated and more densely travelled markets. The contribution of airline cost to price dispersion is limited

A comparative study of airline efficiency in China and India: A dynamic network DEA approach

Using a dynamic network DEA approach, this research examines the efficiency performance of major Chinese and Indian air carriers with a consideration of the airline's internal processes and links as well as the carry-over items that connect consecutive time periods. It is found that two low-cost carriers (LCCs), namely, China's Spring and India's SpiceJet were the most efficient carriers during the period between 2008 and 2015. China's three state-owned airlines performed poorly in both the capacity generation and service stages, particularly the latter. The second-stage regression results confirm that the LCC model and private ownership are significantly associated with better airline efficiency performance. This paper thus calls for continual reforms in China's air transport including further privatisation and policy support for LCCs and private carriers to improve the overall efficiency of this industry

Exploring the roles of high-speed train, air and coach services in the spread of COVID-19 in China

To understand the roles of different transport modes in the spread of COVID-19 pandemic across Chinese cities, this paper looks at the factors influencing the number of imported cases from Wuhan and the spread speed and pattern of the pandemic. We find that frequencies of air flights and high-speed train (HST) services out of Wuhan are significantly associated with the number of COVID-19 cases in the destination cities. The presence of an airport or HST station at a city is significantly related to the speed of the pandemic spread, but its link with the total number of confirmed cases is weak. The farther the distance from Wuhan, the lower number of cases in a city and the slower the dissemination of the pandemic. The longitude and latitude coordinates do not have a significant relationship with the number of total cases but can increase the speed of the COVID-19 spread. Specifically, cities in the higher longitudinal region tended to record a COVID-19 case earlier than their counter-parties in the west. Cities in the north were more likely to report the first case later than those in the south. The pandemic may emerge in large cities earlier than in small cities as GDP is a factor positively associated with the spread speed
