This study proposes and tests two hypotheses concerning the effects of hotel industry operations on air quality based on data of 26 major tourist cities in China from 2002 to 2017. The empirical analyses take two steps. In the first step, panel regression test results reveal that hotel industry operations (measured by hotel sales revenue) significantly raise the value of particulate matter (PM)2.5 (the key indicator of air quality), supporting the first hypothesis that hotel industry operations deteriorate air quality and providing empirical evidence of the adverse impact of the hotel industry on air quality. In the second step, subsample analyses support the second hypothesis that the impact of hotel sales revenue on air quality diminishes over time. The results from the rolling regression tests validate the existence of a diminishing effect of hotel industry operations on air quality.

Abstrak Bawang merah merupakan salah satu komoditas hortikultural penting yang dikonsumsi oleh penduduk Indonesia. Insektisida golongan organofosfat yang digunakan petani bawang merah mengandung senyawa klorpirifos. Penggunaan pestisida dengan intensitas yang terlalu tinggi dan berkelanjutan menimbulkan berbagai masalah kesehatan dan pencemaran lingkungan, penurunan produktivitas tanah, keracunan pada hewan dan manusia. Penelitian ini menganalisis dampak cemaran residu klorpirifos terhadap penurunan kualitas lingkungan pada lahan pertanian. Metode pengambilan sampel menggunakan purposive sampling. Penentuan kadar residu klorpirifos dalam tanah menggunakan gas kromatografi dengan detektor ECD dan uji regresi linear. Kadar residu klorpirifos terbesar pada penggunaan insektisida dengan konsentrasi 1,0% atau 10.000 mg/kg yaitu sebesar 1,83 mg/kg. Hasil pengujian sampel A, B, C, D dan E menunjukkan tingginya kadar residu klorpirifos karena melebihi batas maksimum residu klorpirifos sebesar 2 mg/kg. Dampak cemaran residu klorpirifos dalam tanah dapat menyebabkan perubahan pH, turunnya jumlah organisme dalam tanah serta turunnya kandungan C-organik dan N-total tanah. Abstract  Shallots are one of the important horticultural commodities that are consumed by Indonesians. The organophosphate class insecticide used by shallot farmers contains chlorpyrifos compounds. The use of pesticides with too high intensity and sustainable causes various health problems and environmental pollution, decreased soil productivity, is potentially poisoning to animals and humans. The study analysed the impact of chlorpyrifos residue contamination on environmental quality degradation in agricultural land. The sampling method used was purposive sampling.The determination of chlorpyrifos residue in the soil was undertakeun using gas chromatography with an ECD detector and a linear regression test. The highest residual chlorpyrifos concentration was found in the use of insecticides with a concentration of 1.0% or 10,000 mg / kg, which was 1.83 mg / kg. The test results of samples A, B, C, D and E showed high levels of chlorpyrifos residue because they exceeded the maximum residue limit of 2 mg / kg chlorpyrifos. The impact of chlorpyrifos residue contamination in the soil can cause pH changes, a decrease in the number of organisms in the soil and a decrease in the total soil C-organic and N-content.

The Empirical Analysis

Although city air pollution levels significantly affect the hotel industry, few studies have addressed the impact of air quality management on guests’ cognitive and affective image formation and revisit intentions. Therefore, this research examined the effects of hotel air quality management on the formation of guests’ cognitive and affective images and their revisit intentions. A total of 322 valid samples were obtained by surveying hotel guests who had perceived hotel air quality management activities in the past year, with SPSS 22.0 (IBM, New York, NY, USA) and AMOS 22.0 (IBM, New York, NY, USA) employed for the empirical analysis. The cognitive and affective image constructs revealed that cognitive (perceived value and perceived quality) image influenced revisit intentions but affective image did not. These results provide insights into the need for hotel managers to develop positive cognitive and emotional images through good air quality management and the need to induce customers to revisit based on these images.

One of the major risks facing multinational companies in international trade is the risk of fluctuations in foreign exchange rates. The company makes an effort to reduce the impact of these risks through risk management using a hedging decision. This study aims to test empirically the effect of the company's fundamental variables in predicting hedgings decision. Fundamental variables in this study use financial ratios, namely profitability, leverage, liquidity and growth opportunities. The data in the study used panel data from 2014 to 2017. This study used data analysis techniques using logistic regression tests. Logistic regression test is used because the dependent variable uses dummy data, namely companies that do hedging are given a score of 1 and those who do not do hedging are given a score of 0. The results of the study show that the variable profitability, leverage, and growth opportunities have a positive effect on the hedging decision. The variable liquidity has a negative effect on the hedging decision.

The Impact

The COVID-19 pandemic that occurred in early 2020 caused a decrease in the turnover or income of individual taxpayers. Tax avoidance and tax incentives are considered a strategy by taxpayers to reduce tax payments and manage their funds, especially during this pandemic. The condition of the Taxpayer certainly affects the fulfillment of his tax obligations. On the other hand, taxpayer compliance will have an impact on state revenues. Individual taxpayer perspectives on aspects of accounting and taxation knowledge are important to realize the level of taxpayer compliance. This study also relates the efforts of tax avoidance and government tax incentives as mediating variables. The sample data obtained were 131 individual entrepreneur taxpayers who took advantage of tax incentives in Surabaya and its surroundings. The regression test results showed that accounting and taxation knowledge affect tax avoidance efforts, tax incentives, and taxpayer compliance. The results of the Sobel test show that tax avoidance and tax incentives can mediate the impact of accounting and taxation knowledge on taxpayer compliance. The test results of control variables (gender, education, training, length of business, number of employees, business turnover) showed no effect on taxpayer compliance.

This study makes a novel contribution to the tourism literature by proposing an inverted U–shaped impact of air quality on tourist arrivals and examining this relationship using 58 major tourist cities in China from 2004 to 2015. The estimation of linear and nonlinear dynamic panel regression tests is based on the system generalized method of moments. The linear test results show that air quality measured by the concentration of fine particulate matter (PM2.5) has a significantly negative impact on both inbound and domestic tourist arrivals. The nonlinear test results validate an inverted U–shaped link between air quality and both inbound and domestic tourist arrivals.

Using Data

This article makes an original contribution to the hospitality research literature. It proposes a curvilinear impact of air quality (AQ) on hotel sales (HS) and then empirically tests this nonlinear effect using data from 26 major tourist cities in China from 2002 to 2016. The results of dynamic panel regression test based on estimations of the system generalized method of moments reveal an inverse U-shaped impact of AQ (measured by concentrations of the fine particulate matter, i.e. PM2.5) on HS and thus validate the proposal. Empirical findings offer valuable policy implications for hotel business owners and tourism authorities and policymakers.
