With the rapid transition from an agricultural society to an industrialized society, both economic and social factors could influence the choice of land lease agreement. This paper investigates the choice behavior of land lease agreem...

In agriculture based economies like Pakistan, farmers often shift from farming to off-farm activities as part of an apparent livelihood transition strategy, despite the fact that most of the workforce depends upon farming. In this paper, we try to uncover insights into how livelihood assets, such as human capital, natural capital, economic capital,...

The fundamental purpose of agri-food supply chain management is to restrict opportunism caused by information asymmetry. Traditional Chinese agri-food supply chain management introduces a contract mechanism and a trust mechanism to manage the uncertainty of the agri-food quasi-organization. However, it is almost impossible to improve the efficiency...

The unique “green food” certification scheme in China, which is aimed to ensure environmental and product safety, has attracted increasing attention. In this study, using 398 household‐level survey data from kiwifruit growers in Xixia county of Henan Province, China, alongside a propensity score matching method, we examined the impact of “green foo...

The mixed crop–livestock system is a primary source of livelihood in developing countries.

However, post-disaster recovery and rehabilitation is still a major challenge due to difficulty in targeting the right beneficiaries and the effectiveness of post-disaster aid. This...

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food s...

Using a logistic model, this paper empirically investigated farmers' perception of climate change and its determinants based on a field survey of 1 350 rural households across five major grain producing provinces in China. The results show: i) There is an apparent difference in perception levels for long-term temperature and precipitation changes....

Governments and nongovernmental organizations (NGOs) have promoted environmental and social certification programs for growers because the market for green certification is seen as offering higher prices and higher incomes. Previous studies have examined how “green food” certification affects economic and environmental benefits, but none have studi...

The results show that: (i) access to public climate informat...

Over the past three decades, China has implemented reforms in the agricultural sector in an attempt to increase efficiency and food security. However, China now faces a number of environmental degradation problems, in part, caused by her past agricultural reforms. In this paper we estimate, using a provincial-based panel dataset, a third-order tran...

This paper reports new evidence on the existence of both large and small price divergent clusters for China's energy markets, 2000–2009. The largest convergent price clusters suggest that the coal and gasoline markets are well integrated, however, small convergent price clusters suggest that electricity and diesel markets are proving harder to inte...

There remains ongoing controversy regarding the degree to which Chinese food markets are integrated. Some economists conclude that China's grain economy is well integrated, while others argue that China's gradual reforms have led to fragmented domestic markets while others conclude that previous studies have produced mixed results. To reconcile the...

From 1985, an increasing gap has emerged between the official statistical measures of meat production and meat consumption in China, which has raised concerns from many researchers using such data. In this paper we report the results of 428 observations (survey of 107 urban and rural households×4 quarters) from 7 provinces conducted in 2010, and co...

China's energy needs and its environment are facing great challenges because of the country's rapid urbanization and industrialization.

This chapter is organized as follows: Sect. 8.1 presents the estimated decompositions of energy intensity for firstly, the aggregate economy, followed by the industrial economy (Sect. 8.2). Section 8.3 compares the aggregate economy and industry economy results in order to uncover the differences driving energy intensity in practice. Section 8.4 pr...

In the new millennium, understanding China's energy economy is crucial for politicians, businesspeople and energy economists, as China's energy policy choices will mean both challenges and opportunities for the world in terms of an increasing share of primary energy consumption and investment. This book initially reviews the literature on China's e...

Literature from the past 20 years is reviewed to establish the range of TFP growth estimates that have been made for China's agriculture. This includes some studies that have focussed on either the crops or livestock subsectors. The dispersion of these estimates is used as an input to a slightly-modified GTAP model in order to determine the sensiti...

The paper investigates energy price co-movement over the period 01/1999-12/2005 for China as a whole, and over sub-periods and for seven regions, using panel unit root and panel cointegration tests developed by Pedroni (1999, 2004). The results suggest that not all energy sources are spatially homogenous in prices and the processes of energy price...

Technological change and factor biases are estimated by employing a translog cost function based on a new adjusted dataset for China's hog production sector. Technological change is found not to have been neutral and the factor bias to be statistically significant towards feed grain-saving technology. It is also found that the demand for feed grain...

China has significantly expanded its dairy cow numbers and increased its dairy processing capacity over the last five year in an attempt to meet increased demand for dairy products. China’s net imports of dairy products, however, has expanded at a growth rate in excess of 30% during the same period. To consider why China is still struggling to meet...

The paper tests for energy price co-movement in China over the 'new regime' as part of a strategy to test for the existence of a national energy market. Panel cointegration test statistics suggest that not all energy commodities are spatially homogenous in prices and the processes of energy price cointegration are different over time and over group...

As China enters the twenty-first century the health of the agricultural economy will increasingly rely, not on the growth of inputs, but on the growth of total factor productivity (TFP). However, the tremendous changes in the sector—sometimes back and sometimes forwards—as well as evolving institutions make it difficult to gauge from casual observa...

This study investigates the emergence of energy markets by testing for convergence of energy prices with a new dataset on energy spot prices in 35 major cities in China. Both descriptive statistics and unit root are employed to test the convergence of energy prices for each of four fuel price series. The whole study period is divided into two sub-p...

China's demand for energy has grown to fuel its rapidly expanding industrial, commercial and consumer sectors. At the same time, China has become the second largest consumer of petroleum products having surpassed Japan for the first time in 2003. The environmental consequences of a continuation of these trends will have global implications. Governm...

Many are interested in China's energy situation, however, many energy related issues in China still remain unanswered, for example, what are the potential forces driving energy demand and supply? Previous reviews focused only on fossil fuel based energy and ignored other important elements including renewable and ‘clean’ energy sources. The work pr...
