PurposeThis paper examines the impact of livestock environment regulations (LERs) on the location dynamics of the livestock farming industry. Specifically, it tests whether a “pollution haven effect” (PHE) exists in the Chinese livestock industry.Design/methodology/approachThe authors manually collected LERs data based on the frequency of livestock-related vocabulary in government work reports from 279 prefecture-level cities from 2010 to 2017. Using China's implementation of LERs since 2014 as a natural experiment, the authors employed difference-in-difference (DID) to avoid the endogeneity problem.FindingsLERs have led to a decline in livestock production in regulated areas. Moreover, compared with areas with more stringent LERs – southern China and developed areas, areas where LERs are less stringent – northern China and undeveloped areas, attract more livestock industry. As a result, people in northern China and undeveloped areas are exposed to higher livestock pollution.Originality/valueFirst, most empirical studies on PHE focus on industrial firms. PHE in the livestock industry has received limited attention. This paper aims to fill this gap. Second, this paper regards LERs as an endogenous process and uses the DID method to generate unbiased results. Third, this paper introduces a novel measurement of LERs based on the frequency of livestock-related vocabulary in government work reports from each prefecture city. Fourth, this paper uses prefecture-level data to analyze the PHE of LERs, and thus obtains more reliable results.

Purpose The purpose of this study is to understand the impact mechanism of grassland transfer on herders' production behaviour in pastoral areas. The impact of grassland transfer on herders' livestock production and grazing intensity is quantified.Design/methodology/approach Using the survey data collected for 356 herder households from Inner Mongolia and Gansu, China, quantile regression is employed to assess the heterogeneous effects of grassland transfer on livestock production and grazing intensity. To correct the potential self-selection bias of grassland transfer, the propensity score matching technique is used.Findings Results show that labour, percentage of livestock income and livestock stock are the main factors affecting herders' choice to transfer grassland. The positive effect of grassland transfer on livestock numbers on behalf of those who rented additional grassland is statistically significant but declines with livestock numbers. The sustainability-enhancing effect of grassland transfer on grazing intensity is significant, and the effect becomes larger amongst herder households with higher grazing intensity. The analysis on the impact mechanism shows that grassland transfer significantly promotes the adoption of sustainable grazing modes, such as rotational and seasonal rest grazing, which in turn increases herders' livestock numbers and decreases grazing intensity.Originality/value Few studies have empirically analysed the influence of grassland transfer on livestock numbers and grazing intensity. This study fills this gap by employing a quantile regression to assess the heterogeneous effects of grassland transfer on livestock numbers and grazing intensity, while accounting for self-selection bias. In addition, the authors have examined the influencing mechanisms under which grassland transfer impacts on livestock numbers and grazing intensity.

PurposeThe primary purpose of this paper is to take an in-depth look at the question of whether liberalizing trade in agriculture can generate dynamic productivity gains comparable to those in the manufacturing sector.Design/methodology/approachIn contrast to the manufacturing sector that has generated firm/plant-level trade data, there is a lack of farm-level trade data that are needed for empirical measurement of dynamic productivity gains. Therefore, the authors use thought experiments to analyze the sequence of events that would occur when trade is liberalized for agriculture; delineate the expected behaviors of the actors involved in the trade and draw inferences about whether there would be dynamic productivity gains from agricultural trade.FindingsThe central finding is that there would be little dynamic gain from agricultural trade at the farm level due to the limited role of producers in shaping their international competitiveness. Yet, agricultural trade may generate dynamic gains if states or input supply corporations respond to the freer trade environment by making more investments for research and development (R&D). Further, when intraindustry prevails, there can be productivity gains at the industry level due to the transfer of resources from less to more efficient farm producers.Originality/valueThe findings of the paper are expected to present insights into value for researchers working in the area of agricultural trade; for agricultural trade policymakers in developing countries and for trade negotiators engaged in reforming or designing World Trade Organization (WTO)’s trade rules for agriculture.

PurposeThe purpose of this paper is to examine the influence of clan social capital on the willingness to pay (WTP) and WTP value for collective biogas investment.Design/methodology/approachUsing the Heckman two-stage model and a dataset of 1,265 representative observations from three provinces in Central China collected in 2019, this paper utilizes the contingent valuation method to estimate households' WTP value for collective biogas investment. The paper also explores the heterogeneity between households with different clan governance mechanisms and village governance structures.FindingsThe results indicate that clan networks and trust were likely to improve farmer households' WTP, while clan trust and norms could improve their WTP values. For clans with councils and for clans that can influence the decision-making of village committees, their members were more likely to be influenced by the social capital of their clans to pay for collective biogas investment.Originality/valueThis paper focuses on the WTP and WTP values of households for collective biogas investment, which is often neglected in the research. This paper suggests that clans can be used as a medium to urge households to increase their collective power to reduce carbon emissions and climate crises. The findings empirically contribute to efforts to reduce rural carbon emissions.

PurposeThe contradiction of construction land in economically developed regions is becoming more prominent, and the scale of construction land in some large cities is close to the ceiling. Therefore, China implemented the policy of construction land reduction in 2014. The main objective is to optimize the stock of homesteads and then help to realize rural revitalization by transferring land indexes across regions. Shanghai took the lead in implementing the reduction policy in 2014, for which reduction acceptance data are available. Thus, this paper evaluates the impact of homestead reduction on rural economic development based on data from towns in Shanghai.Design/methodology/approachThis paper uses the difference-in-difference (DID) model to analyze the policy effects of homestead reduction on rural residents' income and industrial integration development. Using economic agglomeration (EA) as a mediating variable, the authors explore how homestead reduction (HR) promotes EA to drive rural economic development and analyze the impact of geographic location and government investment.FindingsHR significantly promotes rural economic development and shows a significant cumulative effect. In the long run, HR can improve rural residents' income and promote industrial integration by promoting EA. The positive effect of HR and EA in suburban regions on industrial integration development is gradually increasing. However, the incentive effect on rural residents' income is weakening. The positive mediating effect of EA is significantly higher in regions with low government investment than in regions with high government investment.Originality/valueThis paper contributes to testing the impact of HR policy on rural economic development and can provide a reference for other regions aiming to implement reduction policy.

PurposeThis study explores how the land tenure system helps in protecting land quantity during agricultural production by estimating the influence of land certification on cropland abandonment, its mechanisms and its heterogeneous effects among groups at the provincial, community and household levels.Design/methodology/approachTo deal with potential homogeneity concerns, the authors investigate the impact of land certification on the area of abandoned croplands using nationally representative panel data from the 2017 and 2019 China Rural Household Panel Survey on 15,000 households across 29 provinces and time-varying difference-in-differences and propensity score matching-difference-in-differences models.FindingsLand certification significantly contributes to the protection of land quantity during agricultural production, and it reduces the area of abandoned croplands by at least 4%. This effect is mainly achieved by improving soil fertility, promoting land transfer, increasing the availability of agricultural subsidies and raising agricultural income. However, while land certification benefits farmers in nonmajor grain-producing areas and western regions, in plain, remote and nonpolitically central villages, and farmers who have not undergone land transfer or land adjustment, it is not beneficial for others.Research limitations/implicationsIn the postepidemic era, food security based on the protection of the amount of cultivated land becomes increasingly important. It is realistic and inevitable to rationally use every inch of cultivated land and curb the cropland abandonment by strengthening land tenure system reform, especially in the case of the insecurity of land tenure.Practical implicationsThere are various factors affecting farmers' cropland abandonment, such as poor soil fertility, unavailable land transfer, too little agricultural subsidies and too low agricultural income, but the root cause is the insecurity of land tenure. Empirical evidence from rural China has shown that a clear definition and effective protection of property rights can help curb the cropland abandonment. Enhancing the land protection behavior of farmers through the reform of land certification and promoting the sustainable use of land are what the reform of land tenure system should be.Social implicationsCultivated land, as the material carrier and endowment basis of grain production, is of great importance to safeguarding national food security, especially in the postepidemic era. At the present stage, it is still necessary for most developing countries to strengthen the construction of land tenure system, to carry out land certification reform and to issue farmers with clearly defined and legally effective land certificates. Equally important, efforts also should be made to promote the diversified utilization of the achievements of the certification after the completion of land certification reform in China and other developing countries.Originality/valueExpropri

PurposeDigital finance has the transformative power to realise financial inclusion. However, evidence on the relationship between digital finance and poverty reduction remains limited. This study examines the mitigating effects of digital financial inclusion (DFI) on vulnerability to poverty in rural China, explores potential mechanisms at the micro-level, and investigates the external conditions for DFI to validate these effects.Design/methodology/approachRural household data from the China Labour Force Dynamics Survey and the regional DFI index compiled by Peking University are used. The probit and mediation effect models are employed to assess the impacts of the DFI on vulnerability to poverty and explore its mechanisms, with an appropriate instrumental variable to mitigate potential endogeneity.FindingsDFI can mitigate vulnerability to poverty in Chinese rural households. Specifically, both sub-indices – coverage breadth and depth of use – have a significant effect. Further analyses based on the mediation model show that improving agricultural productivity, stimulating entrepreneurial activities and promoting non-agricultural employment are the core mechanisms for alleviating poverty vulnerability. Heterogeneity analysis shows that DFI is pro-poor and benefits those who lack economic opportunities. Moreover, adequate endowment in rural households, such as production and human capital, is an external condition for digital finance to mitigate vulnerability to poverty.Originality/valueThis study is among the first to examine the vulnerability-mitigation effects from the perspective of digital finance development, relying on data from a large-scale, nationwide household survey and the regional DFI index. It also checks for the mechanisms and heterogeneity of the effects, which prove the effects can help balance efficiency and equity.

PurposeThis study examines the relative efficiencies of anti-poverty policies implemented in 28 Chinese provinces.Design/methodology/approachThis study uses meta-frontier undesirable dynamic two-stage data envelopment analysis. The authors divide the poverty reduction process into two stages: agricultural production and poverty reduction. Public expenditure is the input for the second stage, and the population below the poverty line is the undesirable output. The authors compute the efficiencies (overall efficiency, efficiency of each stage and the efficiencies of individual inputs and outputs) using meta-frontier analysis for the 28 provinces.FindingsThe results show that: (1) a significant imbalance exists between the eastern and western regions in terms of input-output efficiencies; (2) the poverty reduction stage generally fared better than the agricultural production stage did. In particular, most provinces saw increases in poverty reduction efficiencies between 2013 and 2017; (3) the place-based poverty relief policies introduced in recent years are effective at reducing the poverty rate and reaching the government-set goals and (4) while disposable income has increased steadily over the past few years, income inequality has been exacerbated.Research limitations/implicationsThe results show that: (1) a significant imbalance exists between the eastern and western regions in terms of input-output efficiencies; (2) the poverty reduction stage generally fared better than the agricultural production stage did. In particular, most provinces saw increases in poverty reduction efficiencies between 2013 and 2017; (3) the place-based poverty relief policies introduced in recent years are effective at reducing the poverty rate and reaching the government-set goals and (4) while disposable income has increased steadily over the past few years, income inequality has exacerbated.Originality/valueA large amount of attention and public resources are devoted to fighting poverty and associated market failures in China. The extant literature focuses either on the agricultural production itself or the relationship between human capital and productivity levels. Making use of recent developments of the DEA method, the authors propose a new framework for evaluating the efficiencies of the poverty reduction process. Such a framework has the advantage of giving researchers and policymakers a more detailed diagnosis with regard to the components in the endeavor to eliminate poverty and providing useful information for policymakers to optimize public funds use. Methodologically, the framework is flexible enough to be employed for future research in similar appraisals, at different geographic and scale aggregation levels, for public projects including but not limited to poverty reduction.
