Abstract

Purpose

This paper investigates the relationship between plot size and fertilizer use efficiency (FE) in Chinese large-scale farming and searches for the underlying mechanisms that explain this relationship.

Design/methodology/approach

Based on a household- and plot-level data set of large-scale production units (LSPUs) from Jiangsu and Jiangxi Provinces, the technical and fertilizer use efficiency of large-scale rice production is estimated by applying a translog stochastic frontier production function. The authors impose a monotonicity condition on the translog frontier using a three-step procedure to get theoretically consistent efficiency estimates. A beta regression model is then used to explore the association between plot size and LSPUs' efficiency in fertilizer application.

Findings

The average FE for the sampled plots is around 30%, which shows a large potential for LSPUs to reduce fertilizer use. A U-shaped relationship is observed between plot size and FE. The authors relate this non-linear pattern to the substitution of labour with capital-intensive technology and the efficiency differences in terms of farming performance between family and hired workers.

Originality/value

First, according to the authors’ knowledge, this paper is a first attempt to study the size–efficiency relationship focussing on fertilization practices of large-scale farming. The second contribution lies in the large-scale ranges of the plot-level data set. Third, efforts are made to reveal the mechanisms determining the plot size–FE relationship. Fourth, the authors provide guiding evidence for policymaking, as they show that the size of individual plots deserves equal attention in land consolidation decisions. Methodologically, this paper improves existing estimates of single-factor technical efficiency issued from a restricted production frontier model.

Abstract

Purpose

Soil nutrient management and fertilizer use by farmers are important for sustainable grain production. The authors examined the effect of an experimental agricultural extension program, the science and technology backyard, in promoting sustainable soil nutrient management in the North China Plain (NCP). The science and technology backyard integrates farmer field schools, field demonstrations, and case-to-case counselling to promote sustainable farming practices among rural smallholders.

Design/methodology/approach

The authors conducted a large-scale household survey of more than 2,000 rural smallholders. The authors used a multivariate regression analysis as the benchmark to assess the effect of the science-and-technology backyard on smallholder soil nutrient management. Furthermore, the authors used coarse exact matching (CEM) methods to control for potential bias due to self-selection and the (endogenous) switching regression approach as the main empirical analysis.

Findings

The results show that the science-and-technology backyard program increased smallholders' wheat yield by approximately 0.23 standard deviation; however, no significant increase in maize yield was observed. Regarding soil nutrient use efficiency, the authors found a significant improvement in smallholders' phosphorus and potassium use efficiencies for both wheat and maize production, and a significant improvement in nitrogen use efficiency for wheat production, but no significant improvement of nitrogen use efficiency for maize production.

Originality/value

This study evaluated a novel participatory agricultural extension model to improve soil nutrient management practices among smallholders. The integration of agronomists' scientific knowledge and smallholders' local contextual experiences could be an effective way to improve farmers' soil nutrient management. This study provides the first quantitative estimates based on rigorous impact assessment methods of this novel extension approach in rural China.

Abstract

Purpose

The purpose of this paper is to explore the expansion of agricultural production into marginal lands, also known as “wasteland,” and examine the association between political capital, household income, and using additional marginal lands for agriculture in the Xinjiang Uyghur Autonomous Region of western China.

Design/methodology/approach

The paper uses exploratory data analyses methods, including descriptive statistics, graphical analysis, econometrics and propensity score matching, and data from a 2008 survey of 342 households in Awat County of Aksu Prefecture to explore the role of political capital in an agricultural household setting.

Findings

Preliminary results suggest that wasteland usage has a positive association with income, and that household political capital, in the form of Communist Party membership or being a village cadre, correlates with wasteland usage because it improves access to irrigation water.

Originality/value

A constant topic of debate in China is the role of political capital in influencing livelihoods. The authors aim to add modest insights into this debate and provide a starting point to foster additional debates regarding the role of political capital, rural livelihoods, and natural resource usage.

Abstract

Purpose

Following a guanxi value – buyer‐seller relationship quality – marketing behaviour scheme, this paper aims to explore how traditional guanxi supports small vegetable farmers in modern markets in China.

Design/methodology/approach

Fieldwork was performed in Jiangsu Province, PR China. A stratified random sample of 167 vegetable farmers provided data for empirical testing with partial least squares analysis.

Findings

The findings suggested that the value of guanxi networks is an antecedent to buyer‐seller relationship quality and marketing behaviour in China. Guanxi networks improve the quality of buyer‐seller relationships in terms of interpersonal trust and satisfaction. Buyer‐seller relationships influence smallholders' transaction relationships, their participation in modern markets and choice for formal contracts. Guanxi networks not only support Chinese small‐scale vegetable farmers to get access to modern high‐value markets (e.g. supermarkets and international markets), but also encourage informal transactions in the vegetable business.

Practical implications

Guanxi networks play a critical role in the modern marketing environment in China. Marketing strategies based on personal relationships should be further enhanced in order to increase participation of smallholders in modern markets.

Originality/value

Quantitative evaluation of the effects of the Chinese cultural embedded concept of guanxi in the Chinese agrifood sector fills in an important research gap.

Abstract

Purpose

The purpose of this paper is to investigate the effects of network strength, transaction‐specific investments and inter‐personal trust on business relationship satisfaction for small‐and‐medium‐sized enterprises (SMEs) involved in agri‐food processing and exporting in China.

Design/methodology/approach

Survey data collected from 80 agri‐food SMEs in Jiangsu Province were used for empirical testing. The authors applied an ordered logit regression approach for model estimation.

Findings

The results demonstrate that strong guanxi networks, high level of transaction‐specific investments and inter‐personal trust significantly contribute to a high level of relationship satisfaction for agri‐food SMEs in China. In addition, inter‐personal trust shows a moderating effect on the relationship between transaction‐specific investments and relationship satisfaction.

Practical implications

Business relationships play a critical role in the modern market environment. Relational arrangements (based on guanxi and inter‐personal trust) should be further enhanced in order to yield satisfied business relationships for SMEs in China.

Originality/value

The paper extends our understanding of relationship (guanxi) marketing, as well as marketing practices for agri‐food SMEs in China.

Abstract

Purpose

Experimental auctions are widely used as a non-hypothetical value elicitation method to examine consumer preferences for novel, controversial foods. However, despite its advantages over hypothetical methods, its practice might lead to a wide variety of biases. The purpose of this paper is to provide a list of key cognitive biases and design effects in food auction research and to deliver scientifically underpinned procedures in order to assess, control and reduce them. Its applicability and relevance is examined in auctions on willingness-to-pay for folate (GM) biofortified rice.

Design/methodology/approach

Based on auction literature, a list of 18 biases has been developed. Experimental auctions were conducted with 252 women from Shanxi Province, China to test the occurrence of eight biases, while demonstrating measures to reduce the risk of ten biases.

Findings

The results lend support for three information-related effects, i.e. confirmation bias, conflicting product information effects and a primacy bias, but not for a multiple-good valuation effect, a panel size effect, a trial winner effect and time-related sampling biases. Furthermore, there are no clear indications of social desirability bias, auction fever and a false consensus effect.

Research limitations/implications

This study emphasizes the need to take into account, and measure the risk of various biases when developing, organizing and interpreting experimental auctions. Future research should further extend the list of biases and validate the study findings.

Originality/value

By using a highly topical subject, this study is one of the first to address the potential risk of cognitive biases and design effects in experimental (food) auctions.

Abstract

Purpose

The purpose of this paper is to examine the factors that lead to the controversy within the existing empirical literature on the relationship between land tenure and agricultural investments in China.

Design/methodology/approach

This study conducts a meta-regression analysis (MRA) based on 265 samples from 29 selected studies. These studies are collected from different regions and populations; therefore, this study utilizes a random-effects meta-regression model to control between-study heterogeneity.

Findings

The empirical results show that the variable “land-related long-term investments” significantly affects the relationship between land tenure and agricultural investments. The variables: “ration land,” “land titling” and “land transfer rights” all have significant effects on this relationship, but at different levels. The study area (e.g. “western China,” “central/inland China,” “two regions contained”), “plot level,” “panel data,” “sample size,” “considered endogeneity” and “off-farm employment” variables all significantly influence the relationship. Additionally, the results show that the relationship is significantly affected by the survey time.

Practical implications

Policymakers should treat the existing research conclusions with caution and pay more attention to defining land tenure. The relationship between land tenure and agricultural investments also depends on regional resource availability. Therefore, land property rights policies should be region-specific in order to successfully encourage agricultural investments.

Originality/value

In this study, the author collectively examines existing empirical studies to investigate whether their inconsistent results are affected by research characteristics. To the author’s knowledge, this is the first study that analyzes land tenure and agricultural investments in China using MRA. Future research should refine the definition of land tenure, the selection of agricultural investment types, the research method and the method of data collection.

Abstract

Purpose

The objective of the study is to systematically review the existing research in the topical domain of farmers’ direct link with supermarkets. The authors present a state-of-the-art structure of the field and provide directions for future research in the domain. The major aim of this study is to synthesize the research field and answer some specific questions, like what do we know about this field and where should we be heading.

Design/methodology/approach

A pool of 275 articles published from 2002 to 2022 were retrieved from the Scopus database and analyzed using the R-based Biblioshiny and visualized using VOSviewer. The research design is a mix of quantitative bibliometric technique and qualitative content analysis. Bibliometric method ensures the objectivity while content analysis ensures the scholarly evaluation.

Findings

Major findings include production trend, dominant keywords, leading publication outlets and country-wise analysis of the selected articles. The authors found that sub-domains like economic aspects, participation hurdles and the rise of supermarkets are the most researched topics while operational issues, their pragmatic solutions, sustainability and innovation are the emerging sub-fields that need more academic attention.

Research limitations/implications

The major limitation is the use of single data source, i.e. Scopus, and it is quite possible that useful studies that are not covered by Scopus remain excluded.

Originality/value

This study is one of the first attempts to systematically review the previous research on the selected topic. It will help researchers to understand the present status, identify future research directions, and pursue more reasonable and relevant topics of research.

Abstract

Purpose

The geomagnetic field vector is a function of the satellite’s position. The position and speed of the satellite can be determined by comparing the geomagnetic field vector measured by on board three-axis magnetometer with the standard value of the international geomagnetic field. The geomagnetic model has the disadvantages of uncertainty, low precision and long-term variability. Therefore, accuracy of autonomous navigation using the magnetometer is low. The purpose of this paper is to use the geomagnetic and sunlight information fusion algorithm to improve the orbit accuracy.

Design/methodology/approach

In this paper, an autonomous navigation method for low earth orbit satellite is studied by fusing geomagnetic and solar energy information. The algorithm selects the cosine value of the angle between the solar light vector and the geomagnetic vector, and the geomagnetic field intensity as observation. The Adaptive Unscented Kalman Filter (AUKF) filter is used to estimate the speed and position of the satellite, and the simulation research is carried out. This paper also made the same study using the UKF filter for comparison with the AUKF filter.

Findings

The algorithm of adding the sun direction vector information improves the positioning accuracy compared with the simple geomagnetic navigation, and the convergence and stability of the filter are better. The navigation error does not accumulate with time and has engineering application value. It also can be seen that AUKF filtering accuracy is better than UKF filtering accuracy.

Research limitations/implications

Geomagnetic navigation is greatly affected by the accuracy of magnetometer. This paper does not consider the spacecraft’s environmental interference with magnetic sensors.

Practical implications

Magnetometers and solar sensors are common sensors for micro-satellites. Near-Earth satellite orbit has abundant geomagnetic field resources. Therefore, the algorithm will have higher engineering significance in the practical application of low orbit micro-satellites orbit determination.

Originality/value

This paper introduces a satellite autonomous navigation algorithm. The AUKF geomagnetic filter algorithm using sunlight information can obviously improve the navigation accuracy and meet the basic requirements of low orbit small satellite orbit determination.
