This paper innovatively brings the undesirable output of agricultural carbon emission into the agricultural Total Factor Productivity (TFP) accounting framework as a measure of Green Total Factor Productivity (GTFP) and uses the Slack-based Measure and Malmquist-Luenberger (SBM-ML) index method to measure the agricultural GTFP of 24 provinces in China from 2004 to 2016. Further, the two-step system generalized moment method (GMM) is adopted to reveal the effect of agricultural (Foreign Direct Investment) FDI on the growth of agricultural GTFP and various subitems. We find that the average annual growth rate of agricultural GTFP is 3.1%, and its contribution rate to agricultural growth is 52%; the growth of agricultural GTFP shows that the progress of agricultural technology is accompanied by the deterioration of agricultural technical efficiency; the agricultural GTFP in the Eastern region, the Central region and the Western region increases in a stepped-up form, with an annual growth rate of 3.1%, 3.3% and 3.4%, respectively. Agricultural FDI has a significant promoting effect on agricultural GTFP and subitems, however, it has an inverted U-shaped feature in the long term.

Purpose The purpose of this paper is to present a viewpoint on aligning strategy and execution to produce superior business results. Design/methodology/approach The paper examines the long-term financials of the top ten growers to reveal companies that have continued to grow in good economic times and bad, including the Great Recession. While some companies dug deeper into their core businesses during the financial crisis, others continued to innovate. Findings Where companies continued to focus on strategy execution, they were rewarded, for example, Amazon’s compound annual growth rate for the ten-year period that included the financial crisis was 36.45 per cent; in the past three years, Amazon’s compound annual growth rate (CAGR) has been 56.76 per cent. Most of the top ten long-term growers are headed by the same founder/entrepreneur. Research limitations/implications Look beyond the past three years for models of successful strategy execution. Practical implications For long-term company leaders, entrepreneurs, or turnaround experts, strategic execution is no oxymoron, but a requirement for growth and, ultimately, their unique responsibility. Social implications The paper identifies three major focus areas for strategy teams and company leadership: 1. customer centricity and strategy execution; 2. learning from survivors; and 3. rethinking capabilities and talent. Originality/value As a professor of strategic management and as a consultant to organizations on strategy and marketing transformation, we have focused on the activities that are necessary for leaders to create effective strategy and to execute successfully. We have also been responsible for equipping the larger teams of strategy professionals (and future strategy professionals) who support these leaders with the approaches, the methods, and the tools necessary to plan effectively, to assess effectiveness, and to correct problems in strategy and execution. We bring that perspective to this viewpoint paper.

Abstract. The aim of the work is to prove the appropriateness for minority investors of investing in shares of US banks only with speculative, and not investment intentions; identifying the reasons why long-term investment in the sector is not appropriateness in the presence of a fundamental enabling environment for its development. In the article, the US banking sector is considered as an object of long-term investment for investors who plan to be only minority shareholders, including for citizens of Ukraine. The main research methods in the paper are a graphical analysis of the dynamics of share prices of key US banks and determine the average annual growth rate of the market value of their shares. This average annual growth rate of the value of shares of the respective banks was compared with the dynamics of the stock index S & P-500. The sector is characterized by favorable conditions for development, but the paper proves the hypothesis of the feasibility of investing in shares of US banks only with speculative rather than investment intentions. The factors of inexpediency of long-term investment in this sector in the presence of fundamental favorable conditions for the development of the sector in the country are specified. It is determined that the speculative nature of investments in the US banking sector is due to the lack of sustainable long-term growth of shares of the respective banks at a rate exceeding the growth rate of the stock index S&P-500. The main reasons that hinder the sustainable development of the US banking sector and prevent investment in this sector to outpace the efficiency of investment in the broad market was specified. The main such factors are the significant impact on banking activities of both macroeconomic crises and crises in certain sectors of the economy that are customers of banks. Since the clients of banks are almost all sectors of the economy, the list of possible sectoral crises, which are pass on the banking system in proportion to the volume of lending, is quite significant. This makes investing in the banking sector more risky than investing in other sectors of the economy. The property of the US banking sector and its of state regulation to evolve in the direction of improving the ability to counter economic crises is specified. This property reduces the reliability of forecasts for the development of the studied sector similarly to the dynamics of past periods and forces to plan events in a more optimistic scenario. The heterogeneity of the US banking sector in terms of asset structure and the level of diversification of activities has been identified, which allows individual banks of the country to go through periods of economic crisis in different ways. Keywords: US banking sector, stocks, S&P stock index-500, investments, economic crises. JEL Classification G21, G24, G12 Formulas: 2; fig.: 0; tabl.: 2; bibl.: 21.

Timely understanding of the coastal accretion–erosion dynamics of the Yellow River Delta (YRD) can not only deepen the understanding of the evolution of the delta but also provide scientific support for water-sediment regulation (WSR) in the lower reaches of Yellow River and the implementation of a protection strategy for the Yellow River Estuary. In this long-term study, Landsat images from 1976 to 2018 were acquired, and the cloud processing platform of the Google Earth Engine was used for extraction of coastlines. On the basis of these coastlines, the area and accretion–erosion dynamics were analyzed. Then, after statistical analysis of the interannual and intra-annual variations in runoff and sediment, we discuss the relationship between the accretion–erosion dynamics and the annual runoff and sediment. The results show that (1) the coastline of the YRD lengthened first and then shortened, and the average annual growth rate was 1.48 km/a. (2) The land area of the YRD showed a significant accretionary trend before 1996, with an average annual growth rate of 28.60 km2/a. Then, the area gradually decreased from 1997 to 2001. After WSR was implemented in 2002, the accretion–erosion dynamics gradually became smooth, with an annual growth rate of 0.31 km2/a. (3) After WSR, the maximum annual sedimentation decreased by 79.70%. The average annual sediment discharge accounted for only 6.69% from November to March of the following year during the non-flood season. (4) With the continuous decrease in sediment discharge, the determination coefficient (R2) between the cumulative accretion–erosion area of the estuary and the annual sedimentation decreased from 0.98 in 1976–1996 to 0.77 after 2002. Overall, although WSR has maintained a steady increase in delta land area, it cannot change the long-term decrease in the land area of the delta. The insights gained from our study can provide some references for related coastline research, and will be useful to science community and decision makers for coastal environmental monitoring, management, protection, and sustainable development of the YRD.
