Abstract

Purpose

The purpose of this paper is to analyze the impact of structural changes in hog production manure management practices.

Design/methodology/approach

The data used in this study are obtained from a large-scale nationwide hog producers’ survey in rural China conducted by the Center for Chinese Agricultural Policy, Chinese Academy of Sciences, in 2010. A descriptive analysis between hog manure management and its main determinants was conducted. Based on the collected data, an econometric model on the determinants of hog manure management was constructed and used for analysis.

Findings

The results of this study suggest that the scale of hog production has an important impact on the pattern of hog manure management. Moreover, the results from descriptive statistics and multivariate estimation suggest that smaller hog producers are more likely to apply hog manure to their own lands, while larger hog producers are more likely to sell the manure or find other ways to dispose of it.

Originality/value

This study contributes to the existing literature by examining the impact of structural changes in hog production on hog manure management and the environment.

Abstract

Purpose

Milk is one of the most produced, consumed and protected agricultural commodities worldwide. The purpose of this paper is to assess how trade-opening policies can foster food security in the Chinese milk sector.

Design/methodology/approach

The empirical evidence proposed in our paper is based on time series data from the National Bureau of Statistics of China (2019) and FAOSTAT (2020). Differences in income elasticity between urban and rural areas are estimated by OLS regressions. The data also provide empirical evidence to assess to what extent and to which countries China is resorting to meet its growing demand.

Findings

Per-capita milk consumption of Chinese is rising. The authors’ estimates show that milk income elasticity is higher in rural areas. China is also progressively increasing its dependence on imports. Producers who benefit the most are those from countries implementing trade-opening policies.

Research limitations/implications

Other methods could be applied, by way of example, the gravitational model.

Practical implications

Trade agreements and the removal of barriers could be effective responses to protectionist pressures and to food security concerns.

Social implications

The case examined is of particular interest as it intervenes on food security and safety.

Originality/value

The paper adds value and evidence to the effects of trade on food security in a country with limited and exploited natural resources addressing a health emergency and environmental concerns.

Abstract

Purpose

This paper aims to explain why the quality of infrastructure projects in rural China differs from village to village and how project quality is correlated with project design attributes and governance factors.

Design/methodology/approach

Using primary data collected by the authors on three types of infrastructure projects in villages across China, they created measures of project quality for each village. They then used both descriptive and multivariate approaches to examine how quality varies from village to village and factors correlated with quality.

Findings

Between‐project within‐village quality differences are small and project design has little explanatory power. Between‐village variations are large. There are strong correlations between the ways villages govern themselves and project quality. The authors conclude that it is difficult to make good projects work in communities that lack good governance.

Originality/value

Disaggregated data on the quality of infrastructure (and its determinants) were collected by the authors to allow for variation in the type of infrastructure projects (roads, irrigation, and drinking water) and variation in village governance, making it possible to identify and contrast the effects of project design and village governance factors on project quality. As its chief contribution, this work identifies potential ways to improve the quality of infrastructure projects in rural development.

Abstract

Purpose

This study aims to introduce a method for predicting the remaining useful life (RUL) of bearings based on parallel feature extraction. The proposed model provides prior knowledge and removes redundant handcrafted feature information, additionally, which focuses on the important features at different time scales.

Design/methodology/approach

Distinct from traditional parallel feature extraction methods, which can lead to information redundancy, a one-dimensional convolutional autoencoder is introduced to process selected indicators to remove redundancy and retain useful feature information. To fully capture the important degradation information within different stages in the feature sequences, a novel multi-scale attention feature fusion module is proposed to extract degradation features at different time scales. Considering the impact of degradation modes on RUL prediction, a dual-task prediction module based on no degradation mode labels is designed to obtain accurate RUL.

Findings

Comparative experiments and ablation studies on the PHM2012 bearing dataset verified the effectiveness of the proposed method. Furthermore, the rationality of the selected parameters is confirmed through model parameter analysis.

Originality/value

The novelty of the proposed method is that it not only provides prior knowledge but also further removes redundant information from prior knowledge. In addition, the distribution differences between the original features and their multi-scale convolution results are measured through Kullback–Leibler divergence as the attention scores, which allows the proposed method to focus on important information at different time scales.

Abstract

Purpose

The purpose of this paper is to comprehensively and accurately analyze the supply and demand structural balance of grain in the context of China's agricultural supply-side reform. By subdividing and forecasting the supply and demand, it is beneficial for targeted production in the case of clear demand and supply trends of main grain varieties.

Design/methodology/approach

This paper forecasted and analyzed the demand of main grain varieties by the grey interval forecast, and based on the grey incidence analysis of more influence factors, forecasted the grain production with GM (1,N) model.

Findings

The results show that the demand and yield will keep sustainable growth in the next three years, while there is still a big gap between the supply and demand of the main grain varieties in China and the soybean's production is far behind the growing demand.

Practical implications

This paper can make full use of the information to provide the evidence for government to formulate policies and put forward some correlative suggestions for growers.

Originality/value

In this paper, the grey model technology is applied to the structural reform of grain supply side, and different models are used to predict the structural balance of supply and demand of different kinds of grain. The study of grain supply and demand structural balance in China is vital to ensure grain security in the context of agricultural supply-side reform.

Abstract

Purpose

This article intends to explore the sustainability accounting practices that emerge from the business of artificial forestry in the Qingshui River society of southwest China in the 18th-19th centuries.

Design/methodology/approach

Using a historical approach, we set out to discuss the systematic use of “folk contract” as a tool of tracing accountability in timber trading and in the collective management of community forests in this region, based on the archives of Qingshui River Manuscripts.

Findings

The findings indicate that active transactions of small forest plots facilitated by the prevalent use of folk contracts allow both the landlords and the tenants to easily acquire cashflow needed any time before the harvest, and in turn prevent premature logging and deforestation for crop farming. An “open ledger” bookkeeping system emerged from the extensive contracting practices guarantees the functioning of a dualistic accountability system, where both market value of timbers and “face” value of community members' reputation are preserved for long-term sustainability of local economy, society and ecological environment.

Originality/value

From the perspective of economic anthropology, this study forms the link between the folk contract practice in sustainable forestry of the Qingshui River society and the emancipatory accounting literature.

Abstract

Purpose

This paper therefore aims at systematically estimating the agricultural trade induced farm employment effects in China.

Design/methodology/approach

Using detailed agricultural trade and production data during 1994‐2009, the authors estimate the “labor contents” of agricultural trade flows and use these estimates to compute the farm employment effects.

Findings

The authors find that China's agricultural trade has indeed generally developed along its widely believed comparative advantages and disadvantages; however, the farm employment “creation” effect due to labor‐intensive exports has actually been dominated by the employment “substitution” effect due to increased land‐intensive imports, thereby mostly resulting in negative net farm employment in the post‐WTO accession era.

Originality/value

Findings from this first systematic attempt to estimate the trade‐induced farm employment effects do not lend support to the popular notion that increased agricultural trade would help increase farm employment and have important implications for evaluating current and future trade policy in China and elsewhere.
